Description
The AddOn QSFP28-OTU4-ER4L-AO is a high-performance dual-rate optical transceiver designed for 100GBASE-ER4 and OTU4 applications over single-mode fiber (SMF). Operating across a wavelength range of 1295nm to 1309nm, this module delivers reliable connectivity up to 40km with host FEC enabled (30km without FEC) via a duplex LC connector. It supports aggregate data rates of 103.1Gb/s and 112Gb/s with a 4x25G electrical interface, ensuring seamless integration into modern high-speed networks.
Built to meet QSFP28 MSA, IEEE 802.3ba, and IEEE 802.3bm standards, this transceiver features a cooled 4x25Gb/s LAN WDM DML TOSA transmitter and a 4x25Gb/s APD ROSA receiver for superior optical performance. Digital Optical Monitoring (DOM) provides real-time diagnostics, while low power dissipation (<4.5W) and a single 3.3V power supply enhance energy efficiency. TAA compliance and a Class 1 laser safety certification make it ideal for government, enterprise, and carrier-grade deployments.
