Sorry, 100G QSFP28 transeivers that operate at an industrial temperature range are currently not available, but in development. Please stay tuned. Par FS le 17/02/2018

The FS.COM 100GBASE-SR4 QSFP28 transceivers use 12 fibers OM4 MTP Type B trunk cables for direct connection such as product #68017 and as for 25G to 100G network speed upgrade connection, 8 fibers OM4 MTP-LC Type B harness cable #68047 can be applied. Par FS le 21/10/2017

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.

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.

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.

Dust and contamination can accumulate on transceiver's connectors and cause problems such as reducing the optic launch power. To ensure better connection, FS.COM strongly recommends cleaning both connectors each time you disconnect and reconnect them. FS.COM High Quality One-Push Fiber Optic Pen Cleaner for MTP/MPO Connector is the best cleaning choice for 100GBASE-SR4 QSFP28 transceivers. Par FS le 10/06/2017

No. Network equipment manufacturers do not require that you use only name-brand optics. In fact, when a product fault or defect occurs in the network, and the fault or defect is not attributable to the use of third-party optics, they will continue to provide support for the affected product under warranty or covered by their support program.

FS.COM has been maintaining huge stock level of the 100GBASE-SR4 QSFP28 transceivers in U.S. warehouse, EU warehouse and CN warehouse. As long as the products you order are all in stock, we will ship them out the same day you place your order. As for some specific products or products that have a short stock, we will keep you informed ahead of time before you place your order. Par FS le 05/06/2017

The maximum power consumption of 100GBASE-SR4 QSFP28 transceivers is 3.5W. If it draws greater than 3.5W, FS.COM can not guarantee the performance since there are other dependencies like airflow direction, ambient temperature, elevation and etc. Par FS le 03/06/2017
