Fiber Optic Cable Connectors This lesson discusses fiber optic cable connectors. This lesson covers four standard ones:

  • Straight Tip (ST)
  • Square/Standard Connector (SC)
  • Local Connector (LC)
  • Media Terminal recommended jack (MTRJ)
Video Transcription
00:04
So we saw how we have our different types of fiber optic cables. We have our single mode fiber and our multi mode fiber. But what about the connectors on the end of our fiber optic cables? Well, our fiber optic cables don't just have a single standard connector that we use across the board. We have multiple different connectors, and we're constantly developing new ones
00:23
pretty frequently, actually.
00:25
So we do have a couple of we have our four standard connectors over here that we're going to discuss. But know that there are additional fiber optic cable connectors that you may encounter.
00:36
So are four standard connectors that we're going to talk about for our fiber optic cables. Are S T staining for straight tip
00:44
S C, which stands for square or standard connector LC, which is local connector and MTR J media terminal recommended Jack.
00:55
So are different types of connectors have different looks to them. R S T connector are straight tip connector we actually have an example of on our fiber optic cable here now are straight tick connector is what we're typically going to use for multi mode fiber,
01:12
and our straight tip connector is simply just a locking socket with what looks like a straight tip coming out of it. Now
01:21
this straight tip this outer plastic portion is just the cladding, and the actual inter metal core, if you could look very closely, is a single US tiny little dot of glass rod that's inside of this cable.
01:34
Now we have
01:36
two
01:37
to connectors that we plug into with a cover sheaf when we don't actually, when we aren't actually plugging in the connector. And again, these are going to be our straight tip connectors that were typically going to use for multi mode fiber.
01:52
On the other end of this straight tip connector,
01:55
we have our SC connector are square
02:00
connector or our standard connector now are square. Connector also has a cover over its cladding and its metal core, and our square connector just connects in with instead of a small screw on. It's a click in connector. So with this square tip connector,
02:16
we can see that we can even have a straight tip in a square tip
02:21
on our same length of fibre optic cable. But they do look, they do look very different, and they would plug into ports very differently.
02:30
So
02:31
we have our straight tip and our square tip connector are straight tip again are multi mode fiber are square connector is going to be our square face.
02:42
And then we had else t r l c connector. We don't have a We don't have one of those up here, actually, but RLC connector is going to stand for our local connector. It's there, and it looks similar to our SC connector.
02:53
And then lastly, we have an n t r j Immediate media terminating recommended Jack now are NTR A and N T R J connector is going to be a connector that actually has a, um this isn't an empty r j connector, but in our the in part of our connector,
03:12
we actually have two rods that correspond with two different fiber optic core's inside our cable. Now, why do we have these two different fiber optic cable? Of course. Well, these two different fiber optic course, we have one for sending and wondrous for receiving, so it can better help transmit our data
03:30
when we're using the those particular connectors.
03:34
Um, another one of our connectors that we have up here. We have an optical connector. This isn't one of our connectors that we have listed. This isn't one that we have in our network plus objectives, but it may be one that you encounter is this optical connector. So our optical connected rather than having our rubber protectors? We actually have
03:53
plastic screw on protectors,
03:55
and we'll actually just
03:58
remove these and will notice that we have
04:01
are two different
04:03
clad ings and then again, inside these clad ings protect our actual fiber core, which is a very, very thin court within that actually, transmits are light wavelengths.
04:16
So
04:18
we have our fiber cables. We've talked a little bit about our fiber connectors are straight tip square connector, local connector and R N t R. J. Now with our fiber connectors are fiber connectors and our fiber cables are a little bit more difficult to deal with than just our standard co axle or
04:36
cat. Five cables. Because
04:39
fiber connectors and fiber cables require a bit more a bit more care, we can't take these connectors and we can't roll or these cables, and we can't rolled in this tightly because we don't want to break the core. If we break that court than this cable isn't good anymore. We don't want to break the connectors. We don't have
04:58
easy, simple tools that we can use
05:00
to add on another connector to this core. It's not a simple adding a connector to this fiber cable, as it is a as it is a co axial cable. We can't just I'll just cut this off and then take a connector and slap it on there and then crimp it down. There's specialized training, their specialized tools.
05:17
They're actually used when we are more applying these connectors on here.
05:24
But many environments. A lot of our office environments in our home environments especially we won't be working too often with fiber cable because it is a very it's a technology that's still gaining momentum is still gaining traction in local home or local small business environments.
05:44
Typically the most fiber that you'll have to your location
05:46
maybe in your network closet at your point of demarcation from your Internet service provider, where they have a fiber cable that comes in and plugs into their router, which can understand that fiber connection, and that can translate that into a data connection that we can use an Ethernet infrastructure for but do watch. As fiber becomes
06:06
less expensive and connector and fiber Nick's become less expensive. Fiber network interface cards become less expensive.
06:14
We may see the rise of actual network infrastructures in small environments being replaced are slowly starting to integrate more and more fiber cabling. Because it is faster because we're using light impulses, it can travel distances farther and it isn't says, susceptible to electromagnetic interference.
