Specifications

HPE H3C JL251A Compatible 40GBASE-SR4 QSFP+ Optical Transceiver Module (MMF, 850nm, 150m, MTP/MPO, DDM)

 

The HPE H3C JL251A 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 HPE H3C 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 HPE H3C JL251A 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.

  • What is the difference between Cisco qspf-40g-lr4 and qsfp-40g-lr4-s?
    They are actually the same one.
  • 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.
  • Can this module work at 80°C?
    No, it can't. The working temperature range is 0 to 70°C.

    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.
