Hola, la polaridad del cable MPO que se utiliza junto con el módulo 40G SR4 debería ser el tipo B. Por K***n en 29 agto. 2019

Hi, the "SFP vendor not supported" should be caused by the failure of PID authentication. And our this item is completely compatible, should not have the same issue, don't worry. Por C***n en 17 oct. 2018

Sorry, 40G QSFP+ transeivers that operate at an industrial temperature range are currently not available, but in development. Please stay tuned. Por M***a en 17 mzo. 2018

The FS.COM 40GBASE-SR4 QSFP+ transceivers use 12 fibers multimode MTP® Type B trunk cables for direct connection such as product #68017 and as for 10G to 40G network speed upgrade connection, 8 fibers OM4 MTP®-LC Type B harness cable #68047 can be applied. Por D***e en 12 oct. 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.

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 40GBASE-SR4 QSFP+ transceivers. Por B***s en 22 jun. 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.

On one hand, the FS.COM 40G QSFP+ transceivers with LC interface are used for long-distance transmission over single mode fiber, and those with MTP®/MPO interface are utilized for short distance transmission over multimode fiber. On the other hand, for the FS.COM 40G QSFP+ transceivers with LC interface, they cannot be split into 4x10G as they use 4 wavelengths on a pair of single-mode fibers and do not lend themselves to “splitting” into 4 pairs without substantial complexity to split out the wavelengths. For the FS,COM 40G QSFP+ transceivers with MTP®/MPO interface, they can be used in 4x10G connectivity via an external 12-fiber parallel to 2-fiber duplex breakout cable, which connects the 40G transceiver to four 10G optical interfaces.

FS.COM has been maintaining huge stock level of the 40GBASE-SR4 QSFP+ 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. Por K***e en 21 jun. 2017

Yes, the FS.COM 40GBASE-SR4 QSFP+ transceivers can be be used in a 4 x 10G mode for interoperability with 10GBASE-SR interfaces, making it easier re-use 10G components when developing 40G. The connectivity is achieved by using an 8 fibers OM4 MTP®-LC Type B harness cable #68047, which connects the 40GBASE-SR4 transceivers to four 10GBASE-SR optical interfaces. Por M***y en 13 my. 2017
