Specifications

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

 

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). 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.

 

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.

  • Can this module work at 80°C?
    No, it can't. The working temperature range is 0 to 70°C.
  • Does the qsfp-40g-sr4 transceivers allow 4x 10g connectivity?
    Yes. The connectivity is achieved by using an 8-fibers OM4 MTP-LC Type B break-out cable, which connects the qfp-40g-sr4 transceivers to four sfp-10g-sr optical interfaces.
  • What is the difference between Cisco qspf-40g-lr4 and qsfp-40g-lr4-s?
    They are actually the same one.

    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.
