Specifications

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

 

The Arista Networks QSFPP-40GBASE-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 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 Networks QSFPP-40GBASE-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.

    We had a positive experience with the 40G SR4 and MTP cable. They performed as expected, and our Cisco 2960S accepted them with no problems. Additionally, the price was reasonable, and the service was exceptional. We will definitely consider using qsfptek as a priority supplier for any future needs.

    Initially, I harbored reservations regarding the caliber of the product prior to acquiring it. However, the sales manager's assiduous elucidation of their return policy allayed my fears. Moreover, the fact that they offer a five-year warranty and 24/7 customer service brought about a sense of comfort and led me to endorse procuring from QSFPTEK.

    I bought their optical modules once last year and had no problems with compatibility. So this time I ordered the switch again, and it is now well connected with my equipment, the signal is more stable and the transmission rate is fast.
