Q:
I have a old CWDM gear with a 1310nm sepcial port, is it possible to use this channel for a 40G-LR4 transceiver? By S***s on 05/04/2021

A:
Usually the channel bandwidth of special 1310nm port is ±50nm(1260-1360nm), and this 40G-LR4 has four wavelengths(L0 1264.5-1277.5nm; L1 1284.5-1297.5nm; L2 1304.5-1317.5nm; L3 1324.5-1337.5nm), all are in the range of 1260-1360nm. So I think no problem to use a 40G-LR4 on your special 1310nm port.By R***h on 05/04/2021

Q:
What are the differences between MTP®/MPO interface and LC interface 40G QSFP+ transceivers? By H***s on 06/05/2017

A:
On one hand, the 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 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 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.By B***t on 06/05/2017
