Specifications

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

 

The Cisco QSFP-40G-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 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 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.

    Boksen er godt pakket med god beskyttelse, moduler lastes og festes i en plastbunn. Testet i en ICX 7750, ingen problemer.

    Routerswitch offers this item at about 1w dollars, which is out of my budget. So I think a compatible one may be better. This module is coded to be compatible with Cisco equipment. Thanks to QSFPTEK.

    Plugged into a Juniper EX4600 switch, no issues and not too hot, which are what I needed them for. Items arrived quickly. I will purchase again when I need.

    Works in EX4600s just like OEM. I'm very pleased to know QSFPTEK, they offer great products at only a small fraction of the price of OEM. I plan to buy more here next year to replace my dying optics.

    Last year I purchased 40G DAC here, They're running fine now. Since my business grows, so I need to extend my network capacity. This time I bought 40g lr4 and er4 for linking the 40g platform to 10g access to another building. Running for about three weeks now without issue.

    I have inquired 12pcs Cisco LR4 QSFP+ transceivers on Dec. 2019, then I plan to order mid Jan and pay on credit card. During the period, my excellent sales Talia keep my needs in mind, offered lots of help, such as applying discount price, updating the quotation to my account, sharing the inventory in US... What she had done made the business successful.

    Purchased 8 to use in a nexus 3000series switch QSFP+ ports, instantly recognized and available. Bandwidth and transfer speeds test exactly as expected. Worked flawlessly with no troubleshooting so far. I have bought 10G transceivers here in the past and they've always worked great. These are no exceptions.

    The 40g sr4 runs well over my existing OM3 fiber and compatibility to the Dell PowerSwitch S4128T-ON switch is great. I might buy more from here next month if the performance is stable.
