Cisco 40GBASE-SR4 QSFP Module for MMF (S-Class)
Brand: Cisco (or compatible third-party) · SKU: 40GBASE-SR4 · MPN: QSFP-40G-SR4-S · Category: Networking
The QSFP-40G-SR4-S is a parallel 40Gbps Quad Small Form-factor Pluggable (QSFP+) optical module aligned to IEEE 40GBASE-SR4 optical specifications. It supports aggregate data rates of 40Gbps over 4 independent 10Gbps channels using MPO/MTP multifiber connectors. It supports link lengths of up to 100 meters on OM3 multi-mode fiber and 150 meters on OM4/OM5 multi-mode fiber. This S-Class module operates in the commercial temperature range (0 to 70°C) and does not support 4x10G breakout connectivity or FCoE. It utilizes a single +3.3V power supply and has a power consumption of typically less than 1.5W (or <0.7W for some compatible models).
