Description
The AddOn QSFP-40GBASE-ER4-CN2-AO is a high-performance, TAA-compliant 40GBase-ER4 QSFP+ optical transceiver designed for long-reach 40 Gigabit Ethernet applications. Engineered for seamless compatibility with Ciena® networking equipment, this module delivers up to 40 km transmission over single-mode fiber (SMF) with wavelengths ranging from 1270 nm to 1330 nm using a duplex LC connector.
It supports hot-swappable installation for simplified deployment and Digital Optical Monitoring (DOM) for real-time access to critical performance metrics such as temperature, voltage, and optical power. With robust ESD protection, low EMI metal housing, and full SFF-8436 compliance, this transceiver ensures superior reliability and network stability. Each unit is uniquely serialized, tested for data traffic and application performance, and backed by AddOn’s limited lifetime warranty, making it a trusted choice for data centers, enterprise networks, and access layer deployments.
