Q:

I'd like to know if this transceiver is compatible witch the Arista 9280CR2A-30 Switch

Por F***s en 10 de agto. de 2021

A:

We can confirm that #36207, Arista 40G ER4 module can be compatible with Arista 7280CR2A-30 Switch. You can view the video and see how we perform compatibility tests in our lab (Take the Cisco 40G SR4 as an example): https://www.youtube.com/watch?v=r59WUTUXMmI

Q:

Why should I trust FS.COM compatible transceivers?

Por S***a en 18 de jun. de 2018

A:

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 the 40G ER4 1310nm 40km DOM Transceiver reach full 40km in data transmission?

Por J***n en 09 de my. de 2018

A:

Full 40km reach requires the use of FEC on the host platform. Without FEC, the actual reach is 30km. FEC (Forward Error Correction) is a technique used for controlling errors in data transmission over unreliable or noisy communication channels, with which the maximum transmisson distance of transceiver can be fully supported. It is normally equipped on the host instead of the transceiver.

Q:

What are the differences between MTP/MPO interface and LC interface 40G QSFP+ transceivers?

Por H***s en 05 de jun. de 2017

A:

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.

Q:

Is it necessary to clean a transceiver's optical connector? How to clean the 40G ER4 transceiver?

Por B***s en 03 de jun. de 2017

A:

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 1.25mm LC/MU Connector is the best cleaning choice for 40GBASE-ER4 QSFP+ transceivers.
