Arista QSFP-40G-SR4 Compatible 40GBASE-SR4 QSFP+ Optical Transceiver Module (MMF, 850nm, 150m, MTP/MPO, DDM)

 

The Arista QSFP-40G-SR4 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). 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.

 

QSFPTEK 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 Arista 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 Arista QSFP-40G-SR4 QSFP+ 40G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 40G connectivity.

 

SR4 40G QSFP optics cater to 40 Gigabit Ethernet (40GbE) and 40G to 10G Breakout optical fiber connections, ideal for short-distance applications in the data center, campus network, enterprise core layer, and distribution layer, etc.

    As a distributor based in the US, my customers' top priorities are price and quality, and I am pleased to say that QSFPTEK satisfies both requirements. I have been collaborating with QSFPTEK for a year now and have not received any negative feedback from my customers during this time. On the contrary, my customers frequently offer compliments about the quality of QSFPTEK's products.

    When I was searching the web for a 40G Cisco compatible module solution, a friend recommended me to try the module here. I've tried them on a number of Cisco switches and they all work fine. These mods seem to last a long time. I will definitely buy some more.
