Cisco 4 x 10GBASE-LR QSFP+ Breakout Transceiver Module, MPO Single-Mode

One QSFP+ port, four 10G single-mode links: that is the idea behind the Cisco QSFP-4X10G-LR-S. It is a breakout transceiver with an MPO-12 connector, running at 1310 nm over single-mode fiber with a 10 km reach.

The breakout layout lets a 40G port feed four 10GBASE-LR endpoints, usually through an MPO to LC fan-out cable. The title calls it a 4 x 10GBASE-LR module, so each lane follows the 10G LR standard.

You can order it new, refurbished or used. New and refurbished modules include a choice of 1 year or 3 years of warranty, and used modules include 90 days. Tell us the quantity and whether you also need the fan-out cabling, and we will reply with pricing. Mention the platform on the 10G side too, so we can flag any mismatch early.
