Genuine Nokia 3AL82072AAAA 01 QSFP28 Dual Rate Transceiver 100GBASE-LR4 / OTU4 1310nm 10KM SMF Duplex LC DDM Hot Pluggable 100G Optical Module Fully TestedProduct Overview100% Genuine Nokia 3AL82072AAAA 01 Dual-Rate Carrier-Grade QSFP28 Transceiver, supporting dual standard 100GBASE-LR4 Ethernet and OTU4 OTN Telecom modes. This professional dual-rate module is tailor-made for Nokia carrier transmission and data center convergence networking, perfectly solving the mixed deployment requirements of traditional telecom OTN and modern 100G Ethernet networks.Adopting mature 1310nm LAN-WDM four-channel multiplexing technology, it delivers stable ultra-low-latency transmission with a max reach of 10KM over standard single-mode fiber (SMF). Different from single-rate modules, the dual-rate adaptive design supports free switching between 100G Ethernet data service and OTU4 telecom service, greatly reducing equipment inventory and network upgrade costs. Equipped with high-stability DFB laser and high-sensitivity receiver chip, it features ultra-low bit error rate and strong anti-interference capability, supporting 24/7 uninterrupted carrier-grade stable operation. Built-in complete DDM/DOM real-time monitoring and standard hot-pluggable function realize zero-downtime module replacement and network upgrade. Every unit is 100% fully tested before shipment, with perfect plug-and-play compatibility for Nokia/Alcatel-Lucent 100G transmission, routing and switching platforms.Core Key Selling Points
