After enabling PITFP mode, OLT can reconstruct the tag information and add local tag information based on the original Vender tag.

Insertion loss refers to the decibel ratio of the output optical power to the input optical power of the optical signal in the optical fiber after passing through the active connec...

DHCP Option 82 is enabled at four levels: global, port, service virtual end, and VLAN. This functionality can be achieved without fully enabling each level.

After enabling the PITP function, the content and format of the Vender Tag message added by the OLT to the PPPoE message can be defined as needed.

When a 1:1 optical splitter is connected to the ODN link, the optical power coming out of each outlet of the optical splitter is 1/n of the optical power coming into the optical sp...

For small and medium-sized campuses, ODN planning consists of three points and two lines: the aggregation point, access point, and terminal are called the three points, and the dis...

The cache size of the outbound port priority queue reflects the processing capability of burst messages. The cache size and cache depth percentage of each queue can be configured a...

If a single ONU under a PON port frequently goes online and offline, there may be a problem with the hardware quality of the F port.

Centralized splitting will use more optical cables, and distributed splitting will use more connection equipment, such as optical fiber splitter boxes.

If a rogue ONU with a long light on appears in the GPON system, other ONUs under the same PON port will go offline or go online and offline frequently.

The advantage of PON technology compared to other optical interconnection technologies lies in splitting. Whether to use centralized splitting or distributed splitting requires a c...

In ODN network deployment, the optical cable entering the home is generally called a sheathed optical cable.

In the POL solution, POL light cannot be used to carry CATV services.

In an LACP link aggregation group, only two uplink ports on the same board can be configured as an aggregation group. Cross-board aggregation groups are not supported.

Since the normal ON cannot actively emit light, and the ordinary optical power meter can only be connected to the upstream or downstream optical path at the same time, the ordinary...
