Description
The AddOn Cisco® QSFP28-OTU4-ER4L Compatible Transceiver delivers high-performance, dual-rate 100GbE OTU4-ER4 connectivity over single-mode fiber (SMF) for distances up to 40km with FEC. Operating across 1295nm to 1309nm, this hot-swappable QSFP28 module is designed for seamless deployment in Cisco networking equipment and supports both 103.1Gb/s and 112Gb/s aggregate data rates.
Engineered with a cooled 4x25Gb/s LAN WDM DML transmitter and APD receiver, the transceiver ensures reliable, long-distance data transmission with low power consumption (<4.5W). Digital Optical Monitoring (DOM) enables real-time monitoring of optical parameters, while full MSA, IEEE 802.3ba, and 802.3bm compliance ensures interoperability in a wide range of network infrastructures.
Ideal for 100GBASE-ER4 and OTU4 applications, data center interconnects, and high-performance computing environments, this TAA-compliant module is backed by AddOn’s lifetime warranty and rigorous quality assurance testing for guaranteed compatibility and performance.
