The Cisco QSFP-40G-ER4 compatible 40G QSFP+ transceiver module is equipped with LC duplex connectors, reaching a link up to 10km over OS2 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 40G fiber optic transceiver to achieve real-time operating parameters monitoring.
QSFPTEK manufactured 40GBASE-ER4 QSFP+ module is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-ER4 specifications. Besides, the quad small form-factor pluggable (QSFP) ER4 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-ER4 QSFP+ 40G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 40G connectivity.
ER4 40G QSFP optics cater to 40 Gigabit Ethernet (40GbE) optical fiber connections, ideal for high-performance and long-distance applications in long-haul networks, campus networks, metro networks, etc.
