Fiber Optic Termination Box Introduction

Fiber optic terminal box generally refer to the box shape fiber optic management products used to protect and distribute the optical fiber links in FTTH Networks. Usually the fiber optic boxes include the optical distribution frame and fiber optic terminal box. In general, fiber terminal box is for a few closed cores, and the open type is called ODF (optical distribution frame). Fiber termination boxes can be with 12 cores or 24 cores.

Fiber optic termination box is used to connect the two sections of fiber optic cable. The termination box is the access to the place of the ends of the cable, and then connect to the optical switches via the fiber patch cables. Therefore, the terminal box is usually installed on a 19-inch rack, and can accommodate a number of cable ends. Fiber terminal box is similar with cross connect cabinet, but the role is different. Cross connect cabinet is to connect tow fiber cables, while the terminal box is used to connect the fiber cable terminal with the pigtails with a protective effect. In practical work, roles of cross connect cabinet and fiber termination boxes are different, cross connect cabinets are divided into fiber cable cross connect cabinet and copper cross connect cabinet, which are used when front cable premising, while fiber termination boxes are used for protecting the cable terminal from external damages. Optical distribution frame can also be divided into fiber optic patch panels and copper patch panels, they are the same role with cross connect cabinet, but they are used indoor of carriers’data center.

Applications of fiber termination boxes is universal, they are widely used in telephone, agricultural telephone network system, data and image transmission system, CATV cable television series, indoor cable through force access and branch connection, played the role of the pigtail disk storage and protection of joint.

Actually there are too many fiber optic boxes and fiber management devices, they are hard to count the types, many fiber termination box manufacturers like Ingelen Technology will make the fiber optic boxes according to their own design and they may give the fiber optic boxes different names and model numbers.

Fiber Media Converter To Your Network

Fiber Media Converter, often known as fiber transceivers or Ethernet media converter, are pretty straight forward networking devices that make it possible to connect two different media types like twisted pair like Cat 5 or Cat 6 cable having a fiber-optic cabling network. It can be primarily found in connecting existing copper-based, structured cabling systems, such as twisted pair and also the faster fiber-optic networks. The converters can be employed in the massive metropolitan area networks (MANs), along with large business networks, called enterprise networks.

Fiber optic media converters for a number of POF/HCS fiber technologies, glass MM and glass SM are for sale to interference-free connection and coverage of long distances. Based on the application as well as the required range, distances of 50 m, 300 m, 10 km or 40 km could be covered.

Media converters can also hook up to various optical fiber cables like multimode, single mode or single strand fiber cable. The fiber-optic media converter can extend around 80 miles by using a single-mode fiber, a lot greater distance than the older copper-based systems. Options exists for many distances to match the demands of a certain ethernet to fiber application. And, fiber interface connectors may be dual ST, dual SC, dual LC or single SC type.

Fiber media converters can connect different Local area network (LAN) media, modifying duplex and speed settings. When expanding the reach in the LAN to span multiple locations, fiber transceivers are useful in connecting multiple LANs in order to create one large campus area network that spans over the wide geographic area. In the case of larger LANs, fiber-optic media converters are of help in connecting separate networks that cover a big area. It can make separate LANs operate together large LAN. This may also modify speed and duplex settings. By way of example, a fiber-optic converter that has switching capability can connect a network segment that utilizes half duplex, something that enables two-way communication only one of many ways during a period, to a faster, full-duplex system. A full-duplex system allows for simultaneous two-way traffic. The half-duplex could be a legacy 10baseT system, and also the newer system may be 100baseT, as well as the converter enables these to communicate on the fiber connection.

Media converter types vary from small standalone devices and PC card converters to high port-density chassis systems offering many advanced features for network management. As well as the 10/100/100M Gigabit Ethernet Media Converter is the hottest relating to the main fiber optic media converters.

The 10/100/100M Gigabit Media Converter series was designed to satisfy the massive needs for network deployment and able to extend a copper based Fast network via fiber cable to a maximum distance as much as 100KM.

10/100/1000M SFP Media Converter can convert Optical-Electric Ethernet signals between 10/100/1000M UTP interface (TX) and 1000M optical fiber interface (FX). The traditional 10/100/1000M gigabit Ethernet can be extended for the distance of 100km through optical fiber link. The performance and quality of these products are excellent because of adopting latest Gigabit IC from USA and Taiwan. 6 Group LED indicated lights could fully monitor the running conditions of converters. It isn’t difficult for users to watch and diagnose the failure of converters.

How to Choose Fiber Optic Cable

Most customers are not familiar with fiber optic cabling technology, which makes them to buy the right fiber optic cables for target applications very difficult. The following text describes the methods of identifying several common identifying methods for fiber optic cables, that will help you make right decision when buy optical fiber cable.

1.Cable jacket: Indoor fiber optic cables generally use poly ethylene recorded or flame retardant poly recorded ethylene appearance should be smooth and shiny, with a flexible, easy to peel. Poor low-quality fiber optic cable’s sheathes are poor finished, and easily adhere with sleeve and Kevlar

PE sheath of outdoor fiber optic cable should be high quality black polyethylene, after cabling the skin is smooth, shiny, uniform thickness, no bubbles. Poor-quality fiber optic cable’ sheath is generally produced using recycled materials, this cable’ skin is coarse, due to many impurities within the raw material, you will find a lot of very fine small pits, it will crack or become water seepage after a period’s laying.

2.Optical fibers: Some standard fiber optic cable manufacturer often use the A-level core from top vendors, while the low-cost low-quality fiber optic cables are commonly produced by C-Class, D- grade optical fiber and unsolicited smuggling optical fiber, these fibers are complex sources, with the long factory time, which is already damp and discoloration, often mixed with single-mode fiber and multimode fiber. Some small factories lack the necessary testing equipment, and can not make a judgment of the quality of the optical fiber.

3.Strengthen steel wire: Steel wires of the formal outdoor fiber optic cable manufacturer are phosphated, surface is gray, this makes it will not increase the hydrogen loss, no rust, high strength. Low-quality fiber optic cable is generally replaced with thin wire or aluminum wire Identification method is simple: white appearance, easily be bent, cables with this kinds of steel are high loss of hydrogen, a long time, the two ends for hanging fiber optic closures are more likely to be rust and cracked.

4.Steel armor: The formal manufacturing enterprises using double-sided brush vertical bandage pattern of anti-rust coating steel strip, low-quality fiber optic cable is ordinary iron, usually only one, anti-rust treatment.

5.Loose Tube: Loose tube fiber optic cables are installed with PBT materials, so the casing is strength, no deformation, anti-aging. Low-quality fiber optic cable is usually made with the PVC for
the casing, this casing diameter is thin and easily to be pinched to flat.

6.Fiber paste: Outdoor fiber optic cables fiber cream can prevent fiber oxidation, damp due to water vapor, the inferior fiber optical fiber use only a few fiber cream, seriously affect the life of the optical fiber.

7.Aramid: Also named Mingkaifula, is a high-strength chemical fiber, widely used by the military-industrial. Currently only produced in DuPont and the Netherlands, Akzotion, the price is extremely high. Indoor fiber optic cable and overhead power cables (ADSS) use Aramids as strength member, due to the high cost of Kevlar, the poor quality indoor cable outer diameter is very small.

CWDM/DWDM Mux/Demux and OADM are all fit in with Passive. CWDM and DWDM technology produce an efficient strategy to share one set of fiber strands and hang together various communications interfaces like: 10G, SONET OC-192, STM-64, Fiber Channel 1G/2G/4G, Gigabit Ethernet, OC3/OC12 or OC48 and E1/T1, simply by using different wavelengths of light for each channel. Thus they could expand the proportions from the network without laying more fiber. And that i want to introduce the actual basical description of CWDM Mux/Demux, DWDM Mux/Demux and OADM.

As you know, Mux (Multiplexer) products combine several data signals into one for transporting over the single fiber. Demux (Demulitplexer) separates the signals at the opposite end. Each signal are at an alternative wavelength.

CWDM Mux/Demux
The Coarse Wavelength Division Multiplexing-CWDM Mux/Demux is often a flexible plug-and-play network solution, which helps insurers and enterprise companies to affordably implement denote point or ring based WDM optical networks. CWDM Mux/demux is perfectly suitable for transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks. CWDM tools are widely used in less precision optics and lower cost, un-cooled lasers with lower maintenance requirements. Weighed against DWDM and Conventional WDM, CWDM is a bit more affordable and much less power usage of laser devices. CWDM Multiplexer Modules can be found in 4, 8 and 16 channel configurations. These modules passively multiplex the optical signal outputs from 4 excessively electronic products, send on them somebody optical fiber and de-multiplex the signals into separate, distinct signals for input into gadgets along the opposite end for your fiber optic link.

DWDM Mux/Demux
The Dense Wavelength Division Multiplexing-DWDM Mux/Demux Modules are built to multiplex multiple DWDM channels into 1 or 2 fibers. Depending on type CWDM Mux/Demux unit, with optional expansion, can transmit and receive around 4, 8, 16 or 32 connections of standards, data rates or protocols more than one single fiber optic link without disturbing the other person. DWDM MUX/DEMUX modules provides best and low-cost bandwidth upgrade on your current fiber optic communication networks.

OADM(Optical Add-Drop Multiplexer) is often a device utilized in WDM systems for multiplexing and routing different channels of fiber into or out of a single mode fiber (SMF). OADM is made to optically add/drop one or multiple CWDM/DWDM channels into one or two fibers, provides capacity to add or drop an individual wavelength or multi-wavelengths from the fully multiplexed optical signal. This enables intermediate locations between remote sites gain access to the regular, point-to-point fiber segment linking them. Wavelengths not dropped pass-through the OADM and continue on in direction of the remote site. Additional selected wavelengths can be added or came by successive OADMS if required.

Ingellen provides a range of passive optics. The modules are customizable with a range of WDM/CWDM/DWDM modules and CWDM OADM or DWDM OADM . Ingellen is the best ones to ask about for guidance for use of CWDM, DWDM or WDM technology. CWDM and DWDM Mux/Demux produce an ideal balance of price and satisfaction for multiplexing and demultiplexing in Metro/Access networks.

Details about CWDM Technology

CWDM (Coarse Wavelength Division Multiplexing) is a technology which multiplexes multiple optical signals on one fiber optic strand by making use of different wavelengths, or colors, of laser light to hold different signals. CWDM technology uses ITU standard 20nm spacing within the wavelengths, from 1270nm to 1610nm.

CWDM In comparison with DWDM
Accordingly, they’ve got two important characteristics built into systems employing CWDM optical components which permit easier and for that reason also less expensive than in DWDM systems. CWDM is very easy in terms of network design, implementation, and operation. CWDM works together few parameters that want optimization from the user, while DWDM systems require complex calculations of balance of power per channel, which is further complicated when channels are added and removed or when it’s utilized in DWDM networks ring, particularly if systems incorporate optical amplifiers.

CWDM Function
CWDM modules perform two functions. First, they filter the lighting, ensuring only the desired wavelengths are used. Second, they multiplex or demultiplex multiple wavelengths, which are put on just one fiber link. The real difference is in the wavelengths, which might be used. In CWDM space, the 1310-band as well as the 1550-band are broken into smaller bands, each only 20-nm wide. Inside multiplex operation, the multiple wavelength bands are combined onto just one fiber. Within the demultiplex operation, the multiple wavelength bands are separated from one fiber.

Generally, a CWDM network takes two forms. A point-to-point system connects two locations, muxing and demuxing multiple signals for a passing fancy fiber. A loop or multi-point system connects multiple locations, typically using Add/Drop modules.

CWDM Modules Types
CWDM Modules utilize thin-film coating and micro optics package technology. CWDM modules consider two main configurations: CWDM Multiplexer/Demultiplexer (CWDM Demux) modules and CWDM Add/Drop Multiplexer (CWDM OADM) modules.

Mux products will include a few statistics symptoms in a only for having using a one-time fabric. Demux isolate all of the symptoms inside various terminate. Any value reaches an extra wavelength.

CWDM Mux/demux are created to multiplex multiple CWDM channels into One or two fibers. Within a hybrid configuration (mux/demux), multiple transmit and receive signals can be combined onto a single fiber. Each signal is assigned a different wavelength. At each and every end, transmit signals are muxed, while receive signals are demuxed. CWDM Mux/demux can be a flexible plug-and-play network solution, allowing carriers and enterprise companies to cheaply implement examine point or ring based WDM optical networks. CWDM Mux/demux is modular, scalable and it’s perfectly suited to transport PDH, SDH / SONET, ETHERNET services over WWDM, CWDM and DWDM in optical metro edge and access networks.

The most popular configuration of CWDM mux/demux is 2CH, 4CH, 5CH, 8CH, 9CH, 16CH and 18CH CWDM MUX/DEMUX. 3 Single fiber or dual fiber connection for CWDM Mux/demux can also be found. These modules passively multiplex the optical signal outputs from 4 or higher electronics, send to them merely one optical fiber and then de-multiplex the signals into separate, distinct signals for input into technology along at the opposite end in the fiber optic link.
