Fiber optic transceivers and optical modules

Most of the optical modules are used in the backbone network of the optical fiber network, and the optical transceiver is simply a device to extend the network cable. What is the difference between optical modules and optical transceivers? 1. Optical modules are accessories, generally only used i... Read More

The difference between EPON and GPON of communication terminal

As the two main members of optical network access, EPON and GPON each have their own merits, compete with each other, complement each other, and learn from each other. The following will compare them in various aspects. Rate EPON provides fixed uplink and downlink 1.25 Gbps, adopts 8b/10b line c... Read More

EPON key technology

1.1 Passive optical splitter Passive optical splitter is an important component of PON network. The function of the passive optical splitter is to divide the optical power of one input optical signal into multiple outputs. Typically, the splitter achieves light splitting from 1:2 to 1:32 or even ... Read More
