7.Cable Design Criteria

Pulling Strength: Some cable is simply laid into cable trays or ditches, therefore pull strength is not too important. But other cable may be pulled thorough 2 km or more of conduit. Even with lots of cable lubricant, pulling tension can be high. Most cables get their strength from an aramid fiber, a unique polymer fiber that is very strong but does not stretch - so pulling on it will not stress the other components in the cable. The simplest simplex cable has pull strength of 100-200 pounds, while outside plant cable may have a specification of over 800 pounds.

Water Protection: Every outdoor cable must be protected from water or moisture. It starts with a moisture resistant jacket, usually PE (polyethylene), and a filling of water-blocking material. The usual way is to flood the cable with a water-blocking gel. It's effective but messy - requiring a gel remover. A newer alternative is dry water blocking using a miracle powder - the stuff developed to absorb moisture in disposable diapers. Check with your cable supplier to see if they offer it.

Fire Code Ratings: Every cable installed indoors must meet fire codes. That means the jacket must be rated for fire resistance, with ratings for general use, riser (a vertical cable feeds flames more than horizontal) and plenum (for installation in air-handling areas. Most indoor cables us PVC (polyvinyl chloride) jacketing for fire retardant.

8.Types of Connectors & Adaptors

There are many types of connectorsand adaptor. Choosing which one to use is usually decided by the type of connector already installed in the equipment to be connected.

When deciding upon the proper cable to use, there are only three issues to consider.

Is it compatible with my equipment?

Will I be using it in extremely hazardous conditions?

Does it require special clearance?

Connectors
SC, ST, & LC Connectors are pre-polished, field installable connectors that eliminate the need for hand polishing in the field .Addison fiber optic connectors provide an immediate termination to either single-mode or multimode fibers.

FC Connector

FC connector is the most widely used fiber optic connector in telecommunication industry. Different boot sizes, including 3.0mm, 2.0mm or 0.9mm, are available. Multi-pieces connectors are suitable for factory assembly. Any parts of the FC connectors can be sold separately.

SC Connector

SC connector is another popular type of 2.5mm ferrule connector. With the plastic clip, two simplex connectors can clip together and form a duplex connector. A wide range of SC connectors are available in stock.

ST Connector

The ST connector was originated by AT&T Bell Laboratories for use in premises wiring of buildings and other applications. Available in single-mode and multimode the ST style connector is a low cost and reliable connection solution in the industry.

LC Connector

LC connector provides duplex connections in 50% less space. Available in multimode and single-mode version. Pull-proof.

MU Connector

MU connector is another type of next generation connectors that use 1.25mm ferrule. Its compact design allows more organized and dense front panel arrangement.

MT-RJ Connector

MT-RJ connector is becoming more popular in both datacom and telecom applications which use duplex transceivers. It uses almost the same real estate in patch panels and networking equipment as other 2.5mm ferrule connectors but doubles capacity.

FDDI Connector

Used for networking applications. Duplex connector with fixed shroud, keyed.

SMA Connector

The SMA fiber connector is decreasing in popularity.

D4 Connector

Same as SMA Connector, it is decreasing in usage.

Adaptors

Used to mate industry standard connectors, adapters are available with metal and ceramic alignment sleeves, and are color coded for easy identification. It is available in SC, FC, ST, LC, MU, MT-RJ, MTP & Hybrid.

SC Adaptor

SC adapters are used to mate industry standard sc connectors. Adapters are available with metal and ceramic alignment sleeves, and are color coded for easy identification. The duplex adapters accept two simplex connectors or one duplex connection Hybrids are available for special applications.

FC Adaptor

FC adapters connect industry standard FC connectors and are available in Square-Mount D-Mount and Flange-Mount versions. Our FC adapters feature a metal body for long life and are available with either ceramic or metallic sleeves.

LC Adaptor

LC style adapters are used in high density applications and feature a quick plug in installation. Adapters are available in both simplex and duplex designs and utilize high quality zirconia’s and phosphorous bronze sleeves.

ST Adaptor

ST adapters connect industry standard ST connectors and are available in D-Mount and Flange-Mount versions. ST adapters are available with ceramic or metallic sleeves feature a metal body for long life, and easily install in panel mount applications.

MT-RJ Adaptor

MT-RJ adapters connect industry standard MT- RJ connectors in high-density applications. The adapters are keyed for proper alignment and conform to RJ-45 modular plates. Mounting hardware is not included. Available in single-mode or multimode.
