Cisco QSFP-40G-ER4 Compatible 40GBASE-ER4 QSFP+ Optical Transceiver Module (SMF, 1310nm, 40km, LC, DDM)

 

The Cisco QSFP-40G-ER4 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 40G fiber optic transceiver to achieve real-time operating parameters monitoring.

 

QSFPTEK manufactured 40GBASE-ER4 QSFP+ module is compliant with QSFP+ MSA and IEEE 802.3ba 40GBASE-ER4 specifications. Besides, the quad small form-factor pluggable (QSFP) ER4 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-ER4 QSFP+ 40G transceiver at an affordable price, providing a cost-effective compatible solution for high-performance 40G connectivity.

 

ER4 40G QSFP optics cater to 40 Gigabit Ethernet (40GbE) optical fiber connections, ideal for high-performance and long-distance applications in long-haul networks, campus networks, metro networks, 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.

    I bought these QSFPs for my company. Tested in Arista, Cisco, and Juniper they all recognized the QSFPs and started working right away with zero issues!

    It works well. Very considerate packaging to avoid incidents. It runs on 40Gb/s speed and it is done without problems.

    They shipped from China and were an offline order only, so at first, I was a bit skeptical. Unexpectedly I got the package in a week and the item tests fine with my EX4300 switch.

    Really hassle-free customer support. Firstly I asked a bulk pricing for 40g er4 in live chat. Later we got connected on WhatsApp. The sales rep answered my questions on technical queries, patiently and professionally. Their sales deserve the title of an expert!

    I'm afraid if it works on my mikrotik switch cause the price is too low. I bought one and tested a few weeks on my mikrotik CRS326 switch. The qsfp module works normally. I'm going to buy more next.

    This is a great QSFP item at a good price. Works as it should on my Cisco Catalyst C6824-X-LE series switch and has been tested stable! Will buy again for next project build.

    I've got a Juniper EX4600 and QFX5120-48Y, the 40g sr and 100g sr (part number 26960 ) transceivers do work with them. No sure say for other brands' compatibility

    I want to connect two 7260CX together and the distance between them is about 130 meters. The 40GBASE SR4 may be an ideal choice for me in this case. I ordered these optics and the MTP cables at QSFPTEK. The whole purchase process was smooth and the items I purchased were in stock. Already used in service. No problems. Very satisfied with this purchase.
