Cisco QSFP-40G-SR4-S (S-Class) 

The Cisco 40GBASE-SR4 QSFP module supports link lengths of 100 and 150 meters, respectively, on laser-

optimized OM3 and OM4 multimode fibers. It primarily enables high-bandwidth 40G optical links over 12-fiber 

parallel fiber terminated with MPO/MTP multifiber female connectors. Cisco QSFP-40G-SR4-S is optimized to 

guarantee interoperability with any IEEE-compliant 40GBase-SR4 module. QSFP-40G-SR4-S does not support 

FCoE. 

Cisco QSFP-40G-LR4-S (S-Class) 

The Cisco 40GBASE-LR4 QSFP module supports link lengths of up to 10 kilometer over a standard pair of G.652 

single-mode fiber with duplex LC connectors. The QSFP-40G-LR4-S module supports 40GBase Ethernet rate only. 

The 40 Gigabit Ethernet signal is carried over four wavelengths. Multiplexing and demultiplexing of the four 

wavelengths are managed in the device. QSFP-40G-LR4-S does not support FCoE. 

Cisco QSFP 40G BiDi 

The Cisco QSFP 40-Gbps bidirectional (BiDi) transceiver (Figure 1) is a pluggable optical transceiver with a duplex 

LC connector interface for short-reach data communication and interconnect applications using multimode fiber 

(MMF). The Cisco QSFP 40-Gbps BiDi transceiver offers customers a compelling solution that enables reuse of 

their existing 10 gigabit duplex MMF infrastructure for migration to 40 Gigabit Ethernet connectivity. 

The Cisco QSFP 40-Gbps BiDi transceiver supports link lengths of 100 and 150 meters on laser-optimized OM3 

and OM4 multimode fibers, respectively. 

The Cisco BiDi transceiver complies with the QSFP MSA specification, enabling customers to use it on all QSFP 

40-Gbps platforms to achieve high-density 40 Gigabit Ethernet networks. 

Each Cisco QSFP 40-Gbps BiDi transceiver consists of two 20-Gbps transmit and receive channels in the 832-918 

nanometer wavelength range, enabling an aggregated 40-Gbps link over a two-strand multimode fiber connection.
