Cisco QSFP-40G-ER4 Overview
40GBase-ER4 Optical Transceiver,QSFP+,40G,Single-mode Module 1310nm,40km,LC. The Cisco 40GBASE QSFP+ (Quad Small Form-Factor Pluggable Plus) modules offer customers a wide variety of high-density 40 Gigabit Ethernet connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider transport applications. The Cisco 40GBASE-SR4 QSFP+ Module supports link lengths of 100 m and 150 m respectively on laser-optimized OM3 and OM4 multimode fiber cables. It primarily enables high-bandwidth 40G optical links over ribbon fiber cables terminated with multi-fiber connectors, and could also be used along with ribbon to duplex fiber breakout cables for connectivity to four 10GBASE-SR optical interfaces.
