What does set-top box pon mean?

The set-top box pon is an external connection status display light. The PON light is an indicator of external connection status, and the normal status should always be on. The flashing PON light on the optical fiber cat indicates that the optical fiber cat is trying to establish a connection. Under normal circumstances, the PON data light is always on. If it is flashing, then it is faulty.

Is the flashing of pon light overdue? This flashing or unlit PON light is generally a line fault. It is suggested to check the indoor wiring first to see if there is too large a bending angle of the wiring. If so, it is recommended to restore the line first and then see if you can access the Internet. If you still can't get online, it is recommended to contact local manual customer service to troubleshoot.

Technical characteristics of passive optical network

At present, PON technologies widely used in existing networks include EPON and GPON. The upstream and downstream bandwidth of EPON is 1.25 Gbit/ sec, and GPON is 2.5 Gbit/sec. The downlink and uplink bandwidths are 1.25 Gbit per second. Most EPON and GPON are only equipped with Ethernet interfaces, and POTS and 2M interfaces are optional.

At present, the traditional PON system adopts broadcast technology in downlink and TDMA technology in uplink to solve the problem of multi-user signal multiplexing in all directions. The traditional PON technology adopts WDM technology to realize single fiber bidirectional transmission on optical fiber, which solves the multiplexing transmission of signals in two directions.

PON generally consists of optical line terminal OLT, optical splitter ODU and user terminal ONU3. At present, PON technologies widely used in the current network include EPON and GPON. The upstream and downstream bandwidth of EPON is 1.25 Gbit/s, the downstream bandwidth of GPON is 25 Gbit/s, and the upstream bandwidth is 1.25 Gbit/s.
