StarTech QSFP40LR4ST Cisco Compatible 40GBASE-LR4 QSFP Transceiver Module 1310nm 10km

Overview :

The StarTech QSFP40LR4ST is a professional-grade, hot-swappable fiber-optic transceiver designed for long-range, high-bandwidth 40 Gigabit Ethernet connectivity. It is utilized by network architects and systems engineers to establish high-speed backbone links between data centers, campus buildings, or remote server racks where distances exceed the capabilities of standard multi-mode fiber.

Technically, this QSFP+ module is engineered for 100% compatibility with Cisco networking hardware, specifically programmed to match the Cisco QSFP-40G-LR4. It operates over single-mode fiber (SMF) cabling using a 1310nm wavelength. By utilizing WDM (Wavelength Division Multiplexing) technology, it transmits data over four different lanes to achieve a combined 40Gbps throughput. Featuring LC duplex connectors, it supports reliable data transmission over distances up to 10km (6.2 miles). The module fully supports Digital Diagnostics Monitoring (DDM), allowing administrators to remotely track optical signal strength, temperature, and voltage.

Deployment is optimized for mission-critical infrastructure, offering a reliable, cost-effective alternative to OEM-branded transceivers without sacrificing performance or warranty. Its low power consumption and high MTBF (Mean Time Between Failures) make it an ideal choice for high-density 40G switching environments that require 24/7 uptime and long-distance reach.
