Description
The AddOn ADTRAN® QSFP28-100GB-ER4-AT-AO is a high-performance, TAA-compliant 100GBase-ER4 QSFP28 transceiver designed for long-distance optical networking applications. Providing reliable 100 Gbps Ethernet connectivity over single-mode fiber (SMF), this transceiver supports transmission distances of up to 40 km using wavelengths from 1295 nm to 1309 nm via a duplex LC connector.
Engineered for maximum interoperability, it is guaranteed to be 100% compatible with the equivalent ADTRAN® OEM module. Each unit is hot-swappable and programmed, uniquely serialized, and tested for full compliance with network equipment. Digital Optical Monitoring (DOM) provides real-time visibility into operating parameters for improved network management.
With a rugged, RoHS-compliant design, robust ESD protection, and low EMI metal housing, this module is ideal for access, enterprise, and 100G Ethernet deployments requiring high reliability and extended reach. All AddOn products undergo stringent quality testing and include a limited lifetime warranty.
