Cisco QSFP-4X10G-LR-S Compatible 40GBASE-PSM4 QSFP+ Optical Transceiver Module (SMF, 1310nm, 10km, MPO, DDM)
The Cisco QSFP-4X10G-LR-S compatible 40G QSFP+ transceiver module is equipped with MTP/MPO connector, reaching a link up to 10km over single-mode fiber (SMF). This 40G optical transceiver comes with a bidirectional 4-channel QSFP+ connector, enabling a total of 40 Gbps bandwidth by each channel carrying a 10 Gbps data rate. DOM/DDM (digital diagnostics monitoring) function is supported on the QSFP 40G fiber optic transceiver to achieve real-time operating parameters monitoring.
F-tone manufactured 40GBASE-PSM4 QSFP+ module is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-PSM4 specifications. Besides, the QSFP PSM4 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 for the Cisco QSFP-4X10G-LR-S 40G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 40G connectivity.
PSM4 40G QSFP optics cater to 40 Gigabit Ethernet (40GbE) optical fiber connections, ideal for high-performance and long-distance applications in the data center, enterprise core and distribution layers, campus networks, metro networks, etc.
