 What are the indicators of optical fiber transceiver chip performance? 1. Network management function Network management can not only improve network efficiency, but also guarantee network reliability. However, the manpower and material resources required to develop a fiber optic transceiver with network management function far exceed those of similar products without network management, which are mainly reflected in four aspects: hardware investment, software investment, debugging work, and personnel investment. 1. Hardware investment To realize the network management function of the optical fiber transceiver, it is necessary to configure a network management information processing unit on the circuit board of the transceiver to process the network management information. Through this unit, the management interface of the medium conversion chip is used to obtain management information, and the management information is shared with ordinary data on the network. data channel. Optical fiber transceivers with network management function have more types and quantities of components than similar products without network management. Correspondingly, the wiring is complicated and the development cycle is long. 2. Software investment In addition to hardware wiring, software programming is more important in the research and development of Ethernet fiber optic transceivers with network management functions. The development workload of the network management software is large, including the part of the graphical user interface, the part of the embedded system of the network management module, and the part of the network management information processing unit on the transceiver circuit board. Among them, the embedded system of the network management module is particularly complex, and the R&D threshold is high, and an embedded operating system needs to be used. 3. Debugging work The debugging of the Ethernet optical transceiver with network management function includes two parts: software debugging and hardware debugging. During debugging, any factor in board routing, component performance, component soldering, PCB board quality, environmental conditions, and software programming can affect the performance of an Ethernet fiber optic transceiver. Debugging personnel must have comprehensive quality, and comprehensively consider various factors of transceiver failure. 4. The input of personnel The design of ordinary Ethernet fiber optic transceivers can be completed by only one hardware engineer. The design of the Ethernet fiber optic transceiver with network management function not only requires hardware engineers to complete circuit board wiring, but also requires many software engineers to complete the programming of network management, and requires close cooperation between software and hardware designers. 2. Compatibility OEMC should support common network communication standards such as IEEE802, CISCO ISL, etc., to ensure good compatibility of fiber optic transceivers. 3. Environmental requirements a. The input and output voltage and the working voltage of OEMC are mostly 5 volts or 3.3 volts, but another important device on the Ethernet fiber optic transceiver - the working voltage of the optical transceiver module is mostly 5 volts. If the two operating voltages are inconsistent, it will increase the complexity of the PCB board wiring. b. Working temperature. When choosing the working temperature of OEMC, developers need to start from the most unfavorable conditions and leave room for it. For example, the maximum temperature in summer is 40°C, and the inside of the optical fiber transceiver chassis is heated by various components, especially the OEMC. . Therefore, the upper limit index of the operating temperature of the Ethernet fiber optic transceiver should generally not be lower than 50 °C.
