PRODUCT PRESENTATION
The PHILISUN QSFP28 100G CWDM4 2km LC DX Transceiver is a compact and highly integrated 4x25G module, designed to deliver exceptional reach, bandwidth, density, and cost efficiency for high port-count 100G systems and client-side 100G interfaces. It adheres to the 100G 4WDM-10 MSA, based on CWDM4 MSA version 1.1, and ensures seamless interoperability with other CWDM4 transceivers over distances of up to 2km.

When to choose the 2 km CWDM4 module

This 2 km variant is intended for short-reach CWDM4 links over duplex LC single-mode fiber. It keeps the QSFP28 4 × 25G architecture while using the product-specific receiver limits shown below. Verify host FEC and total link loss against the 2 km table before deployment.
