PRODUCT PRESENTATION
The PHILISUN QSFP28 100G CWDM4 10km LC DX Transceiver is a high-performance, 4x25G module designed to optimize reach, bandwidth, density, and cost for high port-count 100G systems and client-side 100G interfaces. Compliant with the 100G 4WDM-10 MSA, based on CWDM4 MSA version 1.1, this transceiver ensures seamless interoperability with other CWDM4 transceivers over distances of up to 10km.

When to choose the 10 km CWDM4 module

This 10 km variant is intended for CWDM4 links that exceed the 2 km class. It uses a duplex LC interface and single-mode fiber. Before deployment, verify host FEC, connector loss and the link-budget limits in the performance tables below.
