10G SFP+ Transceivers Introduction

10G SFP+ transceiver is one of Gigabit Ethernet fiber optic transceiver modules which are closely related with XFP, X2, Xenpak optical modules. SFP+ transceivers are mainly applied for Gigabit optical networking formation, with transmission rate of 300m, 10km, 40km, 80km. The connection type of SFP+ modules are dual-port LC.

SFP+ optical transceiver module is a new generation of Gigabit optical transceiver, it comply with the ANSI T11 protocol to meet the 8.5G fiber channel and Ethernet 10G applications. Compared with the earlier XFP optical transceiver, its appearance size has reduced about 30%, just is the same sized of the ordinary 1-4G SFP optical modules. SFP+ transceivers only retain the basic elecro-optic photoelectric conversion function, which has reduced the design of the original XFP SerDes, CDR, EDC, MAC, conversion function, thus simplifying the design of 1 0G optical transceiver module, as well as the power consumption. SFP plus optical transceiver has the obvious advantages such as higher-density, lower power consumption and lower system construction cost and other significant
features. The 10G SFP+ transceivers are widely used in Gigabit Ethernet fiber-optic data communications, and it has becomes the mainstream among the Gigabit modules.

SFP+ VS X2, XFP, Xenpak
They are all belong to 10Gigabit optical transceivers. SFP+ are more compact than X2 and XFP. Besides, SFP+ has a strong compatibility which can be interconnect and work together with other 10G XFP, X2, Xenpak optic transceivers. As to the price, the SFP+ has more advantages than other 10G transceivers.

SFP+ is similar with the SFP from the appearance, and they are all with LC connectors, but they are also different from each other: The transmission rata of them are different, SFP+ is 10Gbp/s optical modules, while SFP is generally 1.25G, 155M, 2.5G and other rate.

Typical Protocol Converter

protocol converter is  device used in telecommunications and networking to switch the protocol of one machine to match another protocol, as each protocol based on many factors. Protocol converter allows the different machines to work together — as long as the converter supports the protocols of each machine. The major protocol translation messages involve transformation of data, commands, representation, encoding and framing to achieve the conversion. Most converters have a database with several protocols, and this database is used to convert the initial protocol to another format.

The Protocol Converter connects directly to equipment and converts SNMP, BACnet, and Modbus protocols to one or more of these same protocols for integration into a building management system (BMS) or network management system (NMS). The protocol converter is ideal for situations where data from monitored equipment is incompatible with the protocols used by the BMS or NMS, such as in cases where legacy monitoring systems are present.

Applications of Protocol Converters
Protocol Converter applications vary from industry to industry. The protocol converter can be a software converter, hardware converter, or an integrated converter depending on the protocols.

Some of the key applications are:
Substation Automation;
Building Automation;
Process Automation.

Typical Types
Protocol converter provide local, remote loop-back functions, commanded remote device loop-back in addition to pseudo-random code testing functionality; loop-back functionality can be employed without influence on normal network data verbal exchanges and may definitely not end in this meltdown of network. Typical Protocol converters types include E1/V.35/V.24/RS485/RS232/RS422 protocol converter.

E1 to Ethernet Protocol Converter
E1 to Ethernet 10/100Base-T Protocol Converter adopts the ASIC chip which features simple circuits and compact structure and enhances the reliability of the integrated equipment. It provides data transmission channels at a maximum bandwidth of 2.048M for the Ethernet over coaxial cables and connects two LANs through coaxial cables. E1 port can certainly support 120 ohm/75 ohm amount of resistance in unison.

V.35 to Ethernet Converter
E1 to V.35 protocol converter provides physical conversion between ITU G.703 standard E1 interface and V.35 Interface. Equipments with V.35 interface but without G.703 interface such router and multiplexer is able to transmit data via E1 multiplexer or E1 channel with E1-V.35 protocol converter.

V.35 user port can certainly support N*64K (N=1~32) adaptive rate, which enables it to service central, additional and slave clock modes, so that you can possibly be taken to help a variety of apps; and it also can figure under DTE and DCE modes. E1 to V.35 protocol converter realizes the bi-directional data transfer from E1 port to V. 35 network. This equipment is used in communication network including WAN and LAN, realizing the transfer from E1 channel of SDH or PDH equipment to V. 35, which maybe provided by routers.

E1 to RS232 RS422 RS485 Converter
RS232 port can certainly service this a adaptive rate lower than 115.2K. Ethernet protocol convertor can certainly diagnose this giving in addition to having facts notice connected with E1 port on auto-pilot, in addition to switch off Ethernet function on auto-pilot.

The DDM Function of Fiber Optic Modules

When using SFP transceiver modules, you will often need to know it is with DDM (digital diagnostics monitoring) functions or not, many peoples don’t know well about this term, this article will introduce three roles that DDM plays. DDM gives the end user the ability to monitor real-time parameters of the SFP, such as optical output power, optical input power, temperature, laser bias current, and transceiver supply voltage.

Optical module life prediction
DDM allows network managers to find potential link failures before system performance is affected. Failure notice, the system administrator can switch the business to a backup link or replace the suspicious device, so as to repair the system in the case of uninterrupted business.

Through real-time monitoring of the internal operating voltage and temperature of the transceiver module allows the system administrator to find some potential problems:

Vcc voltage is too high, will bring about the breakdown of CMOS devices; Vcc voltage is too low, the laser does not work properly.
Received power is too high, damage to the receiving module.
Operating temperature is too high, will accelerate the aging of the device.
In addition, the monitoring of the received optical power, can monitor the performance of the lines and the remote transmitter.

Fault Locator
In optical link, locating the fault occurred fast loading of business is essential. ault isolation characteristics allows system administrators to quickly locate the position of a link failure.
This feature can locate the fault in module on the line; locally module or modules in the remote. Quickly locate the fault, reducing the time to repair the system.

Compatibility verification
Another function of DDM is to verify the modules compatibility. Compatibility verification is the analysis of the modules work environment to meet the data sheet or compatibility and related
standards. The performance of the module only in this compatibility work environment can be guaranteed. In some cases, due to environmental parameters beyond the data sheet or standard, will cause
the module performance degradation, thereby result in the transmission error.
Environment like below is not compatible with the modules:
Voltage exceed the specified range
The received optical power is overload or lower than the receiver sensitivity.
Temperature is beyond the standard operating temperature range.

Ingellen Technology, as one of major fiber optic transceiver OEM manufacturers in China, provides a full range of SFP transceivers with or without DDM functions. Besides, you can also wholesale Cisco transceivers which are with 100% compatibilities to all you Cisco equipments.

Why We Need Fiber Media Converter

Fiber Media Converter is an economic devices used in networking more often nowadays, it is definitely an optical converter designed for the fiber optic area. But why it is necessary in network field?

The reason why we need to use fiber media converter is, the Ethernet signals is transmitted by UTP cables, but UTP cables have some shortages, whose transmission distance is 100 meters only). As you know, 100 meters obviously can not meet the requirement in many actual network currently. On the contrary, fiber cables are able to transmit signal for a very long distance and fiber optic signals are more secured and light in weight. So we can use fiber media converter to transform betweem the two types signals and extend the network range. With the manufacturing technology being more and more mature, the cost to use fiber is decreasing. Above reasons are enough to show fiber media converter is necessary and economic. Sometimes the enterprises need to connect their copper based networks directly to the fiber backbone, the fiber media converter also plays a good role there.

Benefits Of Fiber Media Converters

Fiber media converters support many different data communication protocols including Ethernet, Fast Ethernet, Gigabit Ethernet, T1/E1/J1, DS3/E3, as well as multiple cabling types such as coax, twisted pair, multi-mode and single-mode fiber optics. Fiber media converters also ocan connect different lan (LAN) media, modifying duplex and speed settings. When expanding the reach from the LAN to span multiple locations, media converters are useful in connecting multiple LANs to create one large campus area network that spans on the limited geographic area. As premises networks are primarily copper-based, fiber converter can extend the reach of the LAN over single-mode fiber up to 130 kilometers with 1550 nm optics.

The benefits of media conversion include providing a gradual migration path from copper to fiber. Fiber connections can reduce electromagnetic interference. Also, fiber media converters pose like a cheap solution for those who want to buy switches for use with fiber but don’t have the funds to pay for them, they are able to buy ordinary switches and use fiber media converters to make use of with their fiber optic network.

Ingellen offers an extensive choice of full-featured Ethernet to fiber optic media converter solutions, enable the extension of multimode to single mode or multimode to multimode fiber connections to distances up to 160km.

Choose Ingellen Technology for the right product to meet your fiber conversion project needs.

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.
