Description
This Fujitsu® HCD00D20I0000-0-4WDM-40 compatible QSFP28 transceiver provides 100GBase-4WDM-40 throughput up to 40km over single-mode fiber (SMF) using a wavelength range of 1295nm to 1309nm via an LC connector. Designed for high-performance data transmission, it features four 25Gbps cooled DFB-based LAN-WDM lasers, a 4x25G electrical interface, and an APD and TIA array on the receiver side. This hot-swappable transceiver is engineered for reliability in demanding network environments, operating across a wide temperature range from -40°C to 85°C. It also supports digital optical monitoring (DOM) for real-time parameter access and complies with QSFP28 MSA and TAA standards. Fully tested and uniquely serialized, this module ensures seamless compatibility and identical performance to the original Fujitsu® transceiver — backed by AddOn’s limited lifetime warranty.
