MTRJ and SC Connectors question

by road-dog In reply to MTRJ and SC Connectors qu ...

Provided the fiber is the same IE.(62.5/125 MM) then a link between a MTRJ interface on a device and an SC or ST on a patch panel will work. You simply need to procure a patch cord with the proper ends that is the proper length.

MTRJ is good because it offers more terminations in a particular amount of real estate. Many new fiber installations where a large number of fibers are terminated into a single panel or cabinet use MTRJ.

ST and SC connectors have been used for several years, and enjoy a large installed base.

As for quality, I'm not sure which really performs better. If your terminations are of high quality, then both are perfectly adequate for most applications.

thanx very much for your reply
but could you please tell me about links discussing the fiber optic repair and test issues?and how to do this with the equipments.

also please could you tell me can i attach a backbone cable between two buildings using GBIC Fiber Ports ?

thanx again

First, I need to know what is connecting to each end. We're talking GBIC, which is pretty basic.
LX - Long Haul - Single mode Fiber
SX - Short Haul - Multimode Fiber

Transmit connects to receive at the opposite end.

As for testing, This depends on the level of information that you want. When Installing a Campus network, I usually specify that the fiber installer provide Optical Time Domain Reflectometer (OTDR) traces of all segments upon turnover for archive.

This may not be necessary if your application is a simple <12 fiber pull between two buildings a short <200 meters apart.

If you have a simple fiber plant, a "White Light" test will suffice, simply shine a flashlight in one end and look for it at the other. This willmake sure that the fiber is not totally broken and is mapped and numbered corectly.

Your fibers will cross over TX -> RX to hook up the GBICs. Make sure the cross occurs at the main side. That way, you ill gave a standard and wil simplify bughunting at the far end.

If you have Visio, I have a drawing of a campus network fiber distribution you might like to see.

Let me know, and I'll give you an FTP Account on my server so you can download it.

thanks once again for you respond

i will connect at the both end a 3com 4050 switch
one in a building and the one in the other.

does it works or it's required a differnet type of cables.
btw , this switches uses MTRJ connectors.

seoond sure i would like to download in helpful information concerning fiber optic issues.
please could you give me a hint about fiber termination and how it works ?

thnx alot for your support

MTRJ and SC Connectors question

Hii,
Both MTRJ & SC fiber connectors are standard approved connectors. MTRJ is of smaller size compared to SC, thus the fiber patch panel, faceplate etc can accomodate more numbers of fiber connectors. In term of fiber termination, the MTRJ type offers better and easier method. If I'm not mistaken MTRJ is introduced by AMP and other equivalent fiber connector available in the market are FJ (by Panduit)and LC (by Lucent).

Having a cable with MTRJ and SC at both end should not be a problem. However I would recommend you stick to one type of connector at both cable end and if you need to have different connector possibly due to the constraint at Network Equipment, you should use fiber patch cord that have MTRJ and SC at both end. This type of patch cord is available for purchase in the market.

If you plan and design your cabling well, you should be able to avoid using converter.
