Cisco QSFP-40G-LR4 Compatible 40GBASE-LR4 QSFP+ Optical Transceiver Module (SMF, 1310nm, 10km, LC, DDM)

 

The Cisco QSFP-40G-LR4 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 QSFP 40G fiber optic transceiver to achieve real-time operating parameters monitoring.

 

QSFPTEK manufactured 40GBASE-LR4 QSFP+ module is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-LR4 specifications. Besides, the QSFP LR4 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-LR4 QSFP+ 40G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 40G connectivity.

 

LR4 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.

  • 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.

    For almost a month now, I have had these modules installed in our data center. The results have been nothing short of impressive, as they seamlessly connected our Cisco switches, establishing a rock-solid 40Gbe network. I couldn't be happier with my purchase, and the performance of these modules has exceeded my expectations. Without a doubt, I will confidently recommend them to others seeking reliable networking solutions.

    This QSFP item is excellent and reasonably priced. It functions properly on my Cisco Catalyst C6824-X-LE series switch and has been thoroughly tested for stability. I will certainly purchase it again for my next project build.

    I was impressed with the speedy delivery of this item, which arrived on the same day it was promised. Despite its low cost, it works perfectly with my Cisco 2960 switch, meeting all of my needs. I didn't need to configure anything, as it was truly a "plug and play" experience. Overall, I'm very satisfied with this purchase and am already considering buying more in the near future.

    Last month, I made an inquiry for 20 Cisco LR4 QSFP+ transceivers, and I planned to order them in mid-January and pay with my credit card. During this period, my sales representative, Talia, provided excellent service by being attentive to my needs. She went above and beyond by offering me a discounted price, updating my account with the latest quotation, and sharing the available inventory in the US. Thanks to her efforts, the business transaction was a great success.

    The modules were delivered promptly and functioned flawlessly during our pre-deployment testing. We anticipate completing the deployment by the end of the week, and I do not anticipate any challenges. Your products are exceptional, and they seem to be performing well. We are preparing for an extended trial, and during the initial setup, the QSFP modules exhibited similar characteristics to the original Cisco ones.

    I bought a couple of these modules, connecting two Cisco switches, and they work with no issues so far. Would buy it again if I need more.
