Cisco QSFP-40G-CSR-S Compatible 40GBASE-SR4 QSFP+ Optical Transceiver Module (MMF, 850nm, 150m, MTP/MPO, DDM)
The Cisco QSFP-40G-CSR-S compatible 40G QSFP+ transceiver module is equipped with an MTP-12 male fiber connector, reaching a link up to 150m over laser-optimized OM4 multimode fiber (100m over OM3 MMF). It is verified to interoperate with original Cisco switches, including the Catalyst 9400/9500/9600/9800 and Nexus 9300/9500/9800/6000/7000 series, etc. It also supports breakout to 4x 10GBASE-SR SFP+ via MTP/MPO-8 to 4x LC duplex OM3/OM4 breakout cables. This 40G optical transceiver comes with a bidirectional 4-channel QSFP+ connector, enabling a total 40Gbps bandwidth by each channel carrying a 10 Gbps data rate. DOM/DDM (digital diagnostics monitoring) function is supported on the QSFP 40G fiber transceiver to achieve real-time operating parameters monitoring.
F-tone manufactured 40GBASE-SR4 QSFP+ module is compliant with QSFP+ MSA (SFF-8436) and IEEE 802.3ba 40GBASE-SR4 specifications. Besides, the quad small form-factor pluggable (QSFP) SR4 optic has been tested on host devices to ensure full compatibility with Cisco equipment, such as data center switches, enterprise routers, and server network interface cards (NICs). The third-party 40G SFP module is an ideal substitute to the Cisco QSFP-40G-SR4 QSFP+ 40G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 40G connectivity.
