Description
The AddOn Cisco® Compatible TAA 100GBase-BX LR1 PAM4 QSFP28 Transceiver delivers high-speed 100Gbps Ethernet connectivity over single-mode fiber (SMF) with a reach of up to 20km. Operating with 1311nm transmit and 1291nm receive wavelengths on a bidirectional LC interface, this module provides a cost-effective and reliable alternative to Cisco® original optics.
Engineered to meet QSFP28 MSA and SFF-8636 Rev 2.10a standards, it features a 4x25G electrical interface compliant with OIF CEI-28G-VSR. The transceiver supports Digital Optical Monitoring (DOM), enabling network operators to track critical parameters in real time. Its hot-swappable design ensures simple installation and seamless integration into existing Cisco® systems.
Fully RoHS compliant, lead-free, and Trade Agreements Act (TAA) compliant, this optical transceiver is extensively tested for performance, reliability, and compatibility. Backed by AddOn’s limited lifetime warranty, it guarantees consistent and secure operation for demanding data center and enterprise networks.
