Specifications

Juniper Networks QSFPP-40GBASE-SR4 Compatible 40GBASE-SR4 QSFP+ Optical Transceiver Module (MMF, 850nm, 150m, MTP/MPO, DDM)

 

The Juniper Networks QSFPP-40GBASE-SR4 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 Juniper 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 Juniper Networks QSFPP-40GBASE-SR4 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.

    I've been using this optical transceiver with my Juniper switch and have been very impressed with its speed and reliability. the price was very reasonable and the fast delivery also exceeded my expectations.it is a great choice for budget-conscious buyers. I think will support QT again as a loyal buyer.

    The product offered an outstanding value at an affordable price. Additionally, the shipping was exceptionally prompt. I am highly satisfied with my purchase and intend to order from this vendor again in the future. Once I received the transceivers, I immediately connected them to my Juniper QFX3500 with no difficulties whatsoever.

    I have previously bought transceivers from QSFPTEK, and now I can provide feedback on them. They are of good quality and can be compared to the original ones. In fact, QSFPTEK is highly recommended by service providers and has a strong reputation. The transceiver modules arrived promptly, and they worked flawlessly during the pre-deployment testing. We expect to complete the deployment by the end of this week, and I am confident that we will encounter no issues.

    I bought 2 of these (Juniper compatible) to use with Juniper EX4600 switches. They maintain a 40Gb connection without issue. Manufacturing tolerances seem good. The modules aren't loose in the QSFP ports or difficult to insert.
