In the continuous development and improvement of optical transceiver products, users have put forward many new requirements for equipment.
First, today's fiber optic transceiver products are not smart enough. For example, when the optical path of the optical transceiver is broken, the electrical port on the other end of the product will remain open. Therefore, the upper-layer devices, such as routers and switches, will continue to send packets to the electrical interface, resulting in data unreachable. . It is hoped that the majority of equipment providers can achieve automatic switching on the optical transceiver. When the optical path is DOWN, the electrical interface automatically alarms upwards, and prevents the upper device from continuing to send data to the port, enabling redundant links to ensure uninterrupted service.
Second, the fiber optic transceiver itself should be better adapted to the actual network environment. In actual engineering, the use of fiber optic transceivers is mostly inside or outside the corridor, and the power supply situation is very complicated. This requires that the equipment of each manufacturer should support an ultra-wide power supply voltage to adapt to unstable power supply conditions. At the same time, due to the high temperature and ultra-low temperature weather conditions in many areas of China, the impact of lightning strikes and electromagnetic interference is also real. All of these have great influence on the outdoor equipment of the transceiver, which requires the equipment provider to be in the key element. The use of the device, circuit layout and soldering, and structural design must be carefully controlled.
In addition, in terms of network management control, users mostly hope that all network devices can be remotely managed through a unified network management platform, that is, the MIB library of the optical transceiver can be imported into the entire network management information database. Therefore, in the product development, it is necessary to ensure the standardization and compatibility of network management information.
Optical transceivers break the 100-meter limitation of Ethernet cables in data transmission. By relying on high-performance switching chips and large-capacity caches, the optical transceivers provide balanced traffic and isolation conflicts while realizing non-blocking transmission switching performance. Detection of errors and other functions to ensure high security and stability during data transmission. Therefore, fiber optic transceiver products will remain an indispensable part of the actual network formation for a long time. It is believed that the future fiber optic transceivers will continue to develop in the direction of high intelligence, high stability, network management and low cost.
