Description
The AddOn Cisco® Q28-100G-CWDM4-BX-C-AO is a high-performance, TAA-compliant 100GBase-BX CWDM4 QSFP28 transceiver designed for bidirectional 100 Gbps data transmission over single-mode fiber (SMF) up to 2 km. Operating across four CWDM lanes in the 1270 nm to 1330 nm wavelength range, this module leverages an angled-polished LC simplex connector and a 4×25 Gbps electrical interface to ensure seamless network integration and superior throughput.
Engineered to meet or exceed OEM specifications, it is fully compatible with Cisco® hardware and supports Digital Optical Monitoring (DOM) for real-time performance tracking. Built on the QSFP28 MSA standard, the transceiver ensures easy deployment in Ethernet, metro, and enterprise network infrastructures. RoHS-compliant, lead-free, and hot-pluggable, this solution combines reliability with power efficiency (max. 3.5 W) for mission-critical optical networking applications.
