Transceiver modules and jumpers are the two basic components for laying out optical networks. One of the questions that some customers often face is which cable should be used for the transceiver module.
Fiber optic patch cable is used to make patch cables from equipment to fiber optic cabling links. There is a thicker protective layer, which is generally used for the connection between the optical transceiver and the fiber termination box. Fiber patch cord is mainly used in some fields such as optical fiber communication system, optical fiber access network, optical fiber data transmission and local area network.
Fiber patch cord, also called patch cord, refers to the copper or optical cable. By convention, patch cords will be terminated with connectors at both ends. Fiber patch cord is mainly divided into FC patch cord, SC patch cord, ST patch cord, and LC patch cord.
10G Base-T to 10G Base-R Media Converter supports two types media for network connection such as 10GBase-T and 10GBase-FX. The bridge media converter is designed with a 10Gbase Ethernet PHY chip that connects two types segments operation smoothly. This converter can be used as standalone unit or as slide-in module to the 19 converter rack Chassis for use at a central wiring closet.
With the continuous popularization of broadband access, it is necessary to develop more high-speed and low-cost optical communication networks for local area networks, wide area networks, storage networks and other networks. In this context, 10G data link interfaces such as 10 Gigabit Ethernet, SONET OC-192/SDH STM-64 and Fibre Channel have all been standardized.
At the same time, the multi-source agreement (MSA) gave birth to the development of 10Gbps optical transceivers, including 300-pin MSA transponder, XENPAK, XPAK, X2 and XFP. XFP is currently considered to be the most promising 10G module technology. Because its application has nothing to do with the protocol, it has a wide range of applications.
XFP is low in price, its miniaturization, hot-swappable and other advantages make it possible to achieve high port density applications, so it is very popular.
In the key circuit part of the 10G XFP module, the interconnection interface between high-speed ICs is first analyzed, including PECL, LVDS and CML. Then in the laser interface circuit part, different driving methods and coupling methods are compared. Finally, according to the selected chip characteristics, a single-ended AC coupling drive was selected in the design.
Recently, it is much easier to choose an optical module for the network than to choose a matching ofc patch cord. Based on most applications, there are three main factors to consider when choosing a 10G jumper including the transmission medium, transmission distance and transceiver module interface.
10G optical modules can support higher data rates through fiber optic cables. Generally, there are multiple multimode patch cords and single mode patch cords. It is best to choose different optical fibers according to the specified transmission distance requirements.
For optical modules, there is no distinction between single-mode and multi-mode. The so-called single-mode and multi-mode modules refer to the optical device used in the optical end module with which optical fiber to achieve the best transmission performance.
When choosing a cable, the transmission distance is also an important factor to pay attention to. Generally speaking, single-mode fiber is used for long-distance transmission, and multi-mode fiber is used for short-distance. Transceivers tend to use duplex SC or LC interfaces, using one port for transmission and another port for reception.
