MPO/MTP connectors are multifiber ribbon connectors in units of 12 strand and can be stacked (inside the connector).
A single connector can house multiple single rows of 12 fibers, thus enabling transceivers to grow their maximum bandwidth by using multiple strands of Tx/Rx pairs of 10GE, for a total maximum of up to 100GE and 400GE
MPO assemblies are becoming increasingly popular due to high density applications in the This recent transition plays well as carrier networks begin to plan and roll out the new 5G standard. This means carriers are on the hook to push new fiber and adopt the new standards or risk falling behind to the rising demands of end users' content sharing and video/audio streaming
Interestingly, this is also a common problem many enterprises have been facing over the last few years as BYOD and Big Data trends have been putting more and more demands on the network. These two industries are finding a common reprieve by leveraging the MPO/MTP fiber networks and will continue to do so even as transceiver, silicon, improves and pushes to catch up with fiber.
LC Fiber Connector
LC connector was developed by Lucent Technologies and is a more evolutionary approach to achieving the goals of a SFF (small form factor) connector.
LC connector utilizes traditional components of a SC duplex connector having independent ceramic ferrules and housings with the overall size scaled down by one half.
The LC family of connectors includes a stand-alone simplex design; a “behind the wall” (BTW) connector; and the duplex connector available in both single mode and multimode tolerances, all designed using the RJ-style latch.
SC is a snap-in connector also with a 2.5 mm ferrule that is widely used for it's excellent performance. It was the connector standardized in TIA-568-A, but was not widely used at first because it was twice as expensive as a ST. Now it's only a bit more expensive and much more common It's a snap-in connector that latches with a simple push-pull motion. It is also available in a duplex configuration.
