  • 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.

    Perhaps I can write down some of my experience for your reference. First, you could tell the sales manager what scenario you want to buy the device for and your budget. They will depend on your information to give you the most suitable product. After you get the product to get the first test for about a month, during which any problems you can contact their technician to promptly solve your problems. Now the S5300 series works well. All in all, everything feels pretty good.

    Realistically speaking, I can’t find any defects about QSFP-40G-LR4, I don't even know why they can provide so cost-effective compatibility at such a bottom price, maybe expand the market to catch large buyers, who knows, really friendly to me. So far works well, I like it.

    Be honest, I wanted to buy from CISCI at first, but the parts I need out of sale and I can not wait for a more long time, so I buy from QSFPTEK, the fast delivery arrived last Friday, maybe finished test by the end of this week and anything goes wrong I will write here for your reference. Thanks for Talia’s help, she is a very nice person to drive a smith shopping experience.

    After testing for two months, we are able to give our active feedback with QSFPTEK, the QSFPP-40GBASE-SR4 demonstrated good compatibility and reliability, and three years warranty ensures excellent quality, if needed, I will choose QSFPTEK again.
