UST 40GBASE-LM4 QSFP+ Transceiver for Brocade – 40G-QSFP-LM4 TAA Compliant

$401.00

SKU: 40G-QSFP-LM4-US Categories: , , OEM Equivalent: Brocade 40G-QSFP-LM4

The US Transceivers compatible 40G-QSFP-LM4 is a high-performance QSFP+ transceiver module designed for 40 Gigabit Ethernet applications over multimode fiber. This module operates using four parallel lanes of 10Gbps each, utilizing a 1310 nm center wavelength with LM4 optics to support link distances of up to 100 meters over OM3 or OM4 multimode fiber. The MPO/MTP connector interface makes it well suited for structured cabling environments in modern data centers.

Engineered to meet IEEE 802.3 and QSFP+ MSA standards, the US Transceivers compatible 40G-QSFP-LM4 delivers reliable, low-latency connectivity with full Digital Diagnostic Monitoring (DDM) support for real-time visibility into optical performance. This TAA compliant module is built to operate within standard commercial temperature ranges and adheres to RoHS, CE, and REACH regulatory requirements.

Designed as a drop-in compatible replacement for the Brocade 40G-QSFP-LM4, this module is ideal for enterprise networking, data center interconnect, storage area networking, and high-density aggregation deployments where proven performance and compliance are essential.
