Sc has a larger connector housing and a larger 2 5mm ferrule.
Fiber lc vs sc.
1000base sx lc sfp transceiver standard was developed to support lower cost multimode fiber runs in horizontal and shorter length backbone applications.
Developed by lucent technologies the lc connector otherwise known as a lucent connector measures about half the size of an sc connector.
A connector by itself is simplex while a pair of connectors.
While st is not being phased out to the same degree as fc it is starting to see less and less use in favor of lc and sc.
Lc has a smaller connector housing and a smaller 1 25mm ferrule.
The connector end face relies on an alignment key for correct insertion and is then tightened into the adaptor jack using a threaded collet.
3m when it comes to cost comparison sc connectors can be manufactured at a lower price so they cost less than lc connectors.
What s the difference and which one is better you just need to keep three basic points in mind.
There are various fiber connector types in the market such as lc st sc mpo mtp and so on among which sc is one of the most commonly used fiber connectors.
Typical connectors are rated for 500 1 000 mating cycles.
Sc used to be all the rage but now it s lc.
The fc was the first optical fiber connector to use a ceramic ferrule but unlike the plastic bodied sc and lc it utilizes a round screw type fitment made from nickel plated or stainless steel.
Sc is a push pull connector while lc employs a latch as opposed to sc s locking tab.
Lc is covered in the tia connector intermateability standard focis 10 tia 604 10.
This article will introduce sc apc vs sc upc and illustrate their difference for your selection.
To read about the different types of fiber optic cables click here.
There are several common multimode optical fiber cable always apply in fiber optic telecommunications and high speed transmission systems such as st st 62 5 125 lc to st 62 5 multi mode 62 5 125 multimode fiber lc sc sc to sc 62 5 multi mode fiber ect.
All types of fiber cables come in either simplex or duplex configuration.
Further classifying sc by polishing type we have sc apc connector and sc upc connector.
As for the question sc vs lc.
Available in simplex or duplex versions lc connectors can be used with both single mode and multi mode cables.
Lx 5 is like a lc but with a shutter over the end of the fiber.
1000base sx sfp lc transceiver is for multimode fiber cables for less than 550 meters.
The lc sfp lx transceiver is for singlemode fiber cables up to 10km and it also supports the multimode.
A variety of optical fiber connectors are available but sc and lc connectors are the most common types of connectors on the market.
The lc connector uses a 1 25mm ferrule with a retaining tab mechanism.
