With the rapid development of network, the SFP optical module has become an indispensable part of the network system. So how much do you know about the SFP protocol? Today let me give you a brief introduction to the SFP-8472 protocol. Sff-8472 is a multi-source protocol for digital monitoring of...

The new WiFi6 supports 802.11ax mode, so what is the difference between 802.11ax and 802.11ac mode? Compared with 802.11ac, 802.11ax proposes a new spatial multiplexing technology, which can quickly identify and retreat air interface conflicts. Meanwhile, it can identify interference signals mor...

Both single fiber and dual fiber optical modules can transmit and receive. Since the two communications must be able to transmit and receive. The difference is that a single fiber optical module has only one port. Wavelength division multiplexing (WDM) technology is used to combine different rece...

1. Different appearance:  Double fiber optical module: There are two optical fiber sockets, respectively, the sending (TX) and receiving (RX) optical ports. Two optical fibers need to be inserted, and different optical ports and optical fibers are used for data transmission and reception; When du...

The optical module DDM is a means of monitoring parameters. It has not only alarm and warning functions, but also fault prediction and fault location functions. There are two main methods to view the DDM information of the optical module: SNMP and command. 1. SNMP, namely Simple Network Managemen...

1. Optical module life prediction Through the real-time monitoring of the working voltage and temperature inside the transceiver module, the system administrator can find some potential problems: a. If the Vcc voltage is too high, it will bring breakdown of CMOS devices; Vcc voltage is too low, a...
