40G-QSFP-eSR4 QSFP+ Optical Transceiver 850nm Wavelength MPO -12 Receptacle
4 lanes, 850 nm MMF 300m
USource QSFP Modules extend the reach of the IEEE 40GBASE-SR4 interface to 300 and 400 meters on laser-optimized OM3 and OM4 multimode parallel fiber, respectively. Each 10-gigabit lane of this module is compliant to IEEE 10GBASE-SR specifications. This module can be used for native 40G optical links over 12-fiber parallel cables with MPO/MTP female connectors or in a 4x10G mode with parallel to duplex fiber breakout cables for connectivity to four 10GBASE-SR interfaces
Compatible Cisco 40GBASE-SR4 QSFP Module for MMF QSFP-40G-SR4 and 40GBASE-CSR4 QSFP-40G-CSR4
