Cisco Compatible QSFP-40G-SR4 | 40GBASE-SR4 QSFP+ Transceiver MPO MMF 100m

Cisco Compatible QSFP-40G-SR4 40GBASE-SR4 QSFP+ Optical Transceiver (MPO, 850nm, 100m)

Product Overview

The Cisco compatible QSFP-40G-SR4 optical transceiver is a high-performance 40Gbps module designed for short-range data transmission over multimode fiber (MMF). Operating at an 850nm wavelength, it supports distances up to 100 meters on OM3 fiber and 150 meters on OM4 fiber.

This QSFP+ module uses an MPO/MTP multi-fiber connector and transmits data over 4 parallel lanes (4x10G), making it ideal for high-density data center environments requiring fast and reliable 40G connectivity.
