The Development Trend of Optical Fiber Transceiver

First, today‘s fiber-optic transceivers are not smart enough. For example, when the optical circuit of a fiber-optic transceiver is broken, the port on the other end of most products will remain open, so upper-level devices such as routers and switches will continue to send packets to the port, making data unavailable. It is hoped that the majority of equipment providers can realize automatic switching on the optical fiber transceiver. When the optical path is DOWN, the electrical port will automatically alarm upward, and prevent the upper equipment from sending data to the port, and enable the redundant link to ensure that the business will not be interrupted.
Secondly, the optical fiber transceiver itself should be able to better adapt to the actual network environment. In practical engineering, optical fiber transceivers are mostly used in corridors or outdoors, and the power supply situation is very complex, which requires the equipment of each manufacturer to support ultra-wide power supply voltage to adapt to the unstable power supply situation. At the same time as domestic many areas appear ultra-high ultra-low temperature mild weather, lightning, and the influence of electromagnetic interference is real, all of these outdoor equipment such as transceivers influence is very big, which requires the equipment provider in the adoption of key components, circuit board and welding as well as the structure design must be carefully strictly.
In addition, in terms of network management control, most users hope that all network devices can be managed remotely through a unified network management platform, that is, the MIB library of optical fiber transceivers can be imported into the entire network management information database. Therefore, the standardization and compatibility of network management information should be guaranteed in product development.
Optical transceiver in the hundred meters limitations of data transmission through Ethernet cable, rely on the exchange of high-performance chip and large capacity of the cache, the non-blocking switching performance of transmission and truly, and also provides a balanced flow conflict, isolation and detection error function, high safety and stability of data transmission. Therefore, in a very long time, fiber optic transceiver products will still be an indispensable part of the actual network construction. It is believed that the fiber optic transceiver will continue to develop in the direction of high intelligence, high stability, network management and low cost in the future.
