Genuine Nokia 3AL82074AA QSFP28 100GBASE-LR4 Single Rate Transceiver 1310nm 10KM SMF Duplex LC DDM Hot Pluggable 100G Optical Module Fully Tested

Product Overview

100% Genuine Nokia 3AL82074AA Carrier-Grade 100G QSFP28 LR4 Transceiver, single-rate pure Ethernet design, specially built for data center 100G uplink, enterprise core backbone and metro aggregation transmission. Compliant with standard 100GBASE-LR4 protocol, this module delivers stable 100G high-speed low-latency transmission over standard single-mode fiber.

Adopting 1310nm CWDM four-wavelength multiplexing technology, it supports 10KM stable long-distance transmission on universal SMF fiber. Strict single-rate 100G design ensures more stable link negotiation and zero packet loss in pure Ethernet networking scenarios, avoiding compatibility failures caused by multi-rate adaptation. Built with high-precision DFB laser and high-sensitivity receiver chip, featuring ultra-low bit error rate and strong anti-interference performance for 24/7 uninterrupted carrier-grade operation. Equipped with full DDM/DOM real-time monitoring and standard hot-pluggable function, zero downtime for upgrade and replacement. Every unit is 100% fully tested before shipment, perfect plug-and-play compatibility with Nokia/Alcatel-Lucent 100G switching and transmission platforms.
