Photonic Integrated And High-speed Optical Interconnection Technology
Currently, in the field of active optical devices, high-speed optical communication (40G/100G), broadband access FTTH, 3G and LTE wireless communication, high-speed optical interconnection, chips applied in intelligent Fiber Optic Network, device and module technologies are competing to become the hot spots of development. And the photonic integrated, high-speed optical signal modulation technique, high-speed optical device packaging technology, as the representative of the optical device platform technology are also increasingly being valued by the majority of OC manufacturers.
The Technology Development And Breakthrough Of Active Optical Devices
To meet the growing demand for bandwidth, while continuing to reduce the capital, operation and maintenance expenses, will continue to be the two main driving force to promote the development of optical communication technology. In order to meet the evolving needs of the system, the development of active optical communication device involves many technologies, however, in recent years there are several technologies deserve special attention, including 40G/100G high speed transmission device and module technology, the next generation fiber access technology, ROF (Radio Over Fiber) components and module technology, optical integration technology, high-speed interconnect optoelectronic components and modules, etc.
Optical Integration Technology Is Worth Looking Forward
Optical integrated devices due to its low cost, small, easy to large-scale assembly, high work rate, stable performance and other advantages, as early as the 1970s, it caused the world’s attention and research. In the ensuing three decades, with the rapid development of optical waveguide production technology and a variety of fine processing technology, optical integrated devices are heavily into the business, particularly some optical passive components based on Planar Lightwave Circuit (PLC), such as Planar Lightwave Circuit Splitter, arrayed waveguide grating (AWG) and so on, have become hot products in optical communication on the market. In the field of optical active devices, the active integration products are still far from large-scale commercial, but with the successful development of some advanced technologies such as Dispersion Bridge Grating, active devices based on PLC recently made great progress.
The develop direction of optical integration technology can be divided into two categories: monolithic and hybrid integration. Monolithic integration refers to the semiconductor or optical crystal substrate, over the same production process, integrating all the components together, such as: PIC and OEIC technology; the hybrid integration refers to through different production processes, making part of the components, then assembled in the semiconductor or optical crystal substrate.
Previously, the actual production process of Si-based hybrid integration has been quite complex, but recently, a number of research institutions had improved the traditional hybrid integration technology based on flip, and made great progress. Among them, the most remarkable achievements include two items: The first is the University of California at Santa Barbara, in cooperation with Intel company researched hybrid integrated device based on Wafer level; second is the Ghent University based chip and the wafer hybrid integrated devices.
In recent years, the development of optical integration technology, making it quickly became a very worth looking forward platform technology in optic communication, is expected to be widely applied.
High-speed Optical Interconnection Technology Beyond Imagination
High speed optical interconnection technology is realized by parallel Fiber Transceiver and Ribbon Cable or fiber optic cable. Parallel optical module is based on VCSEL array and PIN array,wavelength of 850nm, suitable for 50/125 μm and 62.5/125 μm multimode fiber. Its electrical interface uses standard MegArray connectors in package, optical interface uses standard MTP/MPO ribbon cable. At present more common parallel optical transceiver module has 4 channels and 12 channels. In the current market, the more common high-speed parallel optical modules include: 4 × 3.125Gb/s (12.5Gb/s) parallel optical module, applications such as high-end computer systems, blade servers short distance interconnection; 12 × 2.725Gb/s (32.7Gb/s) parallel optical module, used in high-end switching equipment as well as backplane connection. Parallel optical module applications are gradually becoming more mature.
At present, the rise of applications such as super computer, cloud computing, short-distance high-speed data communication, directly promoting the rapid development of high-pspeed optical interconnection technology, its size of the market and technology development will beyond people’s imagination.
Fiber Connector And Adapter Panel For Optical Links Together
Fiber optic connector is used for the connection of optical fibers or fiber optic cables. The Fiber Optic Connector provide a mechanical connection for the two fiber cables and align both cores precisely.
There have been over 100 connectors developed over the years, but a select few have stood the test of time and beat out their competition. Fiber Optic Connectors according to the different transmission media can be divided into common silicon-based optical fiber single-mode and multimode connectors, as well as other issues such as plastic and as the transmission medium of optical fiber connector; connector structure can be divided into: FC SC, ST, LC, D4, DIN, MU, the MT and so on in various forms, but SC and LC connectors are the most common types of connectors on the market. ST connector is the most popular connector for multimode networks. Different connectors are required for multimode and single-mode fibers.
In addition to connectors that tie two fiber-optic lines together, there are also Adaptor Panels (or fiber adapter plates) that can be used to connect multiple fiber-optic lineself. It enables you to make quick and easy fiber patch panel connections as they can snap into the enclosures easily. In a device such as this, connections can be made between any of the lines plugged into the panel. Though a single adapter panel can usually only hold a dozen or so cables, the panels can also be spliced together, allowing hundreds or thousands of connections to be made.
Specify optical fiber adapter plates for ST-, FC-, SC-, MT-RJ- or LC-type connections. Adapter plates are compatible with all wall and rack mount optical fiber enclosures and available in 6 simplex and duplex, 8 simplex and duplex and 6 quad configurations with fiber counts of up to 24 per adapter plate. They mount easily by means of plunger locks (“pushpins”). ST, FC, SC and LC connec-tor plates can be equipped with 62.5-μm and 50-μm adapters suitable for multimode applications or a sisingle modenly version is available with adapters outfitted with zirconia ceramic sleeves. Our SC and LC 10G multimode laser optimized adapter uses zirconia ceramic sleeves.

How To Install Twisted Pair Cable Connectors
Figure1
Both types of connectors are made of plastic with metal “fingers” inside them (as you can see in Figure 1). These fingers are pushed down into the individual conductors in a twisted-pair cable during the crimping process. Once these fingers are crimped and make contact with the conductors in the twisted-pair cable, they are the contact points between the conductors and the pins inside the RJ-11 or RJ-45 jack.
Tools for Connector Crimping
Figure2
Figure3
The last tool you’re going to use is a cable tester. This device tests for a continuous signal from the source connector to the destination and also tests the quality of that connection
Check to ensure all conductors are making contact and that all pins have been crimped into their respective conductors. If the connector didn’t crimp properly, cut off the connector and redo it.
Telephone Modular Jack Wiki
Modular connector, electrical connectors originally used in telephone wiring, now is used for many other purposes. Probably the most well known applications of modular connectors are for Phone Jacks and for Ethernet jacks in Ethernet Cabling, both of which are nearly always modular connectors.
Modular connectors also called Telephone Modular Jack, RJ connector (RJ stands for Registered Jack- a physical connector interface most often used for telephone wire terminals), and Western jack/plug. The term “modular connector” arose from its original use in a novel system of cabling designed to make telephone equipment more modular. This includes the 4P4C handset connector which is sometimes called an “RJ9″ or an “RJ22″ — but such RJ specifications are absent in the current FCC documents. 8P8C modular connector type is often called RJ45 plug, and RJ45 plugs are also used with different signals, such as for Ethernet over twisted pair. RJ11 is the most familiar of the registered jacks, due to the fact that virtually all single line telephone jacks in most homes and offices use this connector type.
Modular jacks are defined as “male” or “female”, depending on if they will be inserted or if a component will be inserted into them. Male connectors are called plugs, while female connectors are called jacks or sometimes sockets. Plugs are used to terminate loose cables and cords, while jacks are used for fixed locations on surfaces such as walls, panels and on equipment. Phone jacks and plugs have very similar packaging even though the functions that they perform are not similar at all. Modular jacks come in a wide range of different types from modular connectors and plugs, phone jacks, computer and Ethernet jacks, to Internet connections and electronic components.
Another very common type of modular jack is that of the telephone or Ethernet jack. This small unit is connected to a telephone cord which then transmits a telephone analog signal from a special phone outlet placed on a wall, desk or cubicle to the actual phone unit. If the telephone jack becomes loose or is removed from the telephone outlet for any reason, the signal is lost and phone calls cannot be made. Telephone jacks are generally small square plastic attachments which contain tiny wires inside as well as a release tab.
A third type of modular jack belongs to the personal computer that can be connected to a local or worldwide network, such as the Internet. While older desktop computers or those connecting to an internal network can connect via a telephone jack sending a signal down telephone lines facilitated by the use of a dialing modem, many computers use cable or digital signals to connect to the Internet. In some cases, the signal can also be sent wirelessly through a router, which is connected to this modular jack with a special cable.
Modular jacks are in wide use in many buildings around the globe due to their ease of use. They are an inexpensive alternative to direct wiring of electronic devices. In many buildings, the most common form of modular jack is the electrical connection, cord, or plug. Outlets which provide electricity to electrical-powered devices connect them via a wire or cord that hooks together in a special modular ending, such as a set of metal prongs found on the average electrical cord. Once the prongs are inserted correctly into the associated outlet, electrical power is transferred from the outlet to the device and it is ready for use. The modular jack must correspond with the outlet in order for this power exchange to take place.
