Description
The AddOn Cisco® QDD-400G-LR8-S Compatible TAA 400GBase-LR8 PAM4 QSFP-DD Transceiver delivers ultra-high-speed 400 Gbps Ethernet connectivity for next-generation data center, enterprise, and service provider networks. Designed for seamless compatibility with Cisco® equipment, this hot-swappable optical module enables high-capacity data transmission over single-mode fiber (SMF) up to 10 km using wavelengths from 1270 nm to 1330 nm.
Engineered with a QSFP-DD Type 2 form factor and compliant with IEEE 802.3bs standards, it ensures superior signal integrity, low latency, and high-performance network scalability. The module supports Digital Optical Monitoring (DOM) for real-time performance metrics and is fully TAA compliant for government and enterprise procurement. Each transceiver is rigorously tested for 100% compatibility, guaranteed to initialize and perform identically to the OEM equivalent, and backed by AddOn’s limited lifetime war.
