1×4 800GHz LAN WDM Devices

How to use 25G SFP28 LWDM transceiver in the network?

The connection of the 25G SFP28 LWDM transceiver is similar to the connection of the CWDM / DWDM module, and it needs to be used with the LWDM combiner/demultiplexer.
Just insert four 25G SFP28 LWDM modules into two 25G switches respectively. Then, use four single-mode fiber optic cables to connect the SFP28 LWDM module and the LWDM combiner/demultiplexer respectively. The connection between two LWDM combiners and splitters can be realized through a single-mode fiber optic cable.
In short, the 25G SFP28 LWDM transceiver can support multi-channel signal transmission on a single optical fiber. It makes up for the large dispersion of 25G CWDM modules and the high cost of 25G DWDM transceiver lasers, provides stable transmission, and saves a lot of fiber resources for 5G fronthaul.
25G SFP28 LWDM is one of the stable and cost-effective solutions in the 5G fronthaul network, and it has great development potential in the future.

LWDM Splitter, also known as LAN WDM Splitter and LAN WDM, along with Filter WDM splitter, dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
