Both ends of the optical fiber jumper wavelength transceiver module must be consistent, meaning that both ends of the fiber must be the same wavelengths of light module, a simple distinction is the color of the light module to be consistent. Under normal circumstances, short-wave optical module using multimode fiber (orange fiber), long wavelength module uses single-mode fiber (yellow fibers), in order to ensure the accuracy of data transmission.

Fiber jumpers by different transmission media can be divided into common silicon-based optical fiber single-mode, multimode jumpers, as well as other issues such as the fiber jumper with plastic transmission medium; by connector structure can be divided into: FC jumper, SC jumper, ST jumper, LC jumpers, MTRJ jumper, MPO jumper, MU jumper, SMA jumper, FDDI jumper, E2000 jumper, DIN4 jumper, D4 jumpers so a variety of form. The more common fiber jumper can be divided into FC-FC, FC-SC, FC-LC, FC-ST, SC-SC, SC-ST and the like.

Fiber optic patch cords are used as devices to the jumper fiber optic cabling links. It has a thick layer of protection, generally used in the connection between the Optical and the terminal box.

GPON (Gigabit-Capable PON) technology is based on standard ITU-TG.984.x the latest generation of broadband passive optical access standards, with high bandwidth, high efficiency, large coverage, rich user interface and many other advantages, is large Most operators deemed to achieve broadband access network business, comprehensive transformation of the ideal technology.

EPON is the best combination of several technology and network structure. EPON uses multipoint structure, passive optical transmission, offers a variety of services over Ethernet. At present, IP/Ethernet applications accounted for more than 95% of the entire LAN communication, EPON since the economic and efficient use of the above-described structure, will become an end-user access network connecting the most efficient communication method.

PTN packet transport product is designed, its main features is reflected in the following areas: flexible scheduling networking capability, multi-service transport capabilities, comprehensive carrier-class security, carrier-class OAM capabilities, with business sense and end service provisioning management capacity, low cost per bit transmitted.

PTN technology is essentially a packet-based routing architecture to provide multi-service technical support. It is a more suitable for IP service transmission technology, while inheriting the traditional advantages of optical transmission, including a good network scalability, a rich operation and maintenance (OAM), fast protection switching and clock transmission capability, high reliability and safety sex, the whole concept of network management, end to end service configuration and precise alarm management. These advantages PTN is the traditional router and Enhanced Ethernet technology can not match, which is distinct from the important attributes of both. We can understand the concept of PTN technology from the following four aspects.

Including optical receiver module, optical transmitter module, optical transceiver module and optical transponder modules.

Currently, reconfigurable OADM has become the development direction. In addition to using the optical switch dynamically select the upper and lower wavelengths, the use of a tunable filter is a hot spot.
