Why should I trust FS.COM compatible transceivers? By Soza on June 07, 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.

What are the differences between MTP/MPO interface and LC interface 40G QSFP+ transceivers? By Hawkes on June 05, 2017
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.
