Description
The AddOn QSFP28-OTU4-CWDM4-AO is a high-performance, MSA-compliant optical transceiver designed to deliver 100GBase-CWDM4, OTU4, and 128G Fibre Channel connectivity over single-mode fiber (SMF) up to 2 km. Operating across CWDM wavelengths from 1270 nm to 1330 nm, this module uses a duplex LC connector and supports four lanes at 28.05 Gbps each, providing a total aggregate data rate of 100 Gbps.
Ideal for high-capacity data center, metro, and enterprise network applications, this hot-pluggable transceiver includes Digital Optical Monitoring (DOM) for real-time performance diagnostics and monitoring. It meets IEEE 802.3ba, QSFP28 MSA, and OTU4 standards, is fully RoHS compliant, TAA compliant, and backed by AddOn’s limited lifetime warranty.
Engineered for reliability and seamless interoperability, the QSFP28-OTU4-CWDM4-AO ensures consistent performance in demanding environments, offering superior ESD protection, low EMI, and optimized power efficiency for next-generation high-speed networks.
