Questions & Answers

Ask a question

  • Q:

    What kinds of custom choices are offered in FS.COM? By Glasscock on August 08, 2017


    As for customized transceivers, FS.COM offers regular custom choices such as compatibility, transmission distance, operating temperature, label pattern, label colors and etc. What's more, FS.COM welcomes any inquiry for customized products and solutions for all need and specifications.

  • Q:

    Why should I trust FS.COM compatible transceivers? By Soza on July 08, 2017


    Besides the price advantage we have compared to branded transceivers, FS.COM compatible transceivers also maintain the same performance and reliability. To satisfy our customers' needs of high performance, all of our transceivers are tested multiple times in mainstream original brand switches in our test center before shipped out.

  • Q:

    Can 100G QSFP28 interfaces interoperate with SR10 based 100GbE? By Husnain on June 21, 2017


    No. The 100G QSFP28 form factor has just 4 electrical lanes, which is not enough to support 10 lanes of 10G electrical interface. A 100G QSFP can only support a 4x10G or 4x25G electrical interface, which can be used as 4x10GbE or 4x25GbE, but not 10x 10GbE.As a result the 100G QSFP SR4 cannot interoperate with SR10 based 100GbE transceivers.
