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

After comparing the service, price and account manager service, I chose to buy this 40G SR4 from QSFPTEK. Its price can save my cost, the service is also perfect, the key point is that the account manager always replies to messages in time and recommends suitable products for me, and the price is also great!

Perhaps I can write down some of my experience for your reference. First, you could tell the sales manager what scenario you want to buy the device for and your budget. They will depend on your information to give you the most suitable product. After you get the product to get the first test for about a month, during which any problems you can contact their technician to promptly solve your problems. Now the S5300 series works well. All in all, everything feels pretty good.

I consulted the availability for OEM labels and the programmers for SFPs. They provided them and offered me a quote for dozens of transceivers at 10g, 25g, 40g, and 100g. I got the sample order last week, tested to be great! I will buy more here.
