INTRODUCTION TO FIBER OPTIC CABLES

Fiber optic cables are use to transmit data at the speed of light. This cable type completely different than the copper cables. Fiber optic cables offer high bandwidts and low losses which allow highdata transmittion rates over long distances.

There are mainly three common types of fiber optic cables.

1.Single-mode

2.multymode

3.granded index

These types are mostly used in communication systems and also they have established medical,military,scanning,imaging,and sensing applications.

INTRODUCTION TO FIBER OPTIC CONNECTORS

Todays and future communication technology demands fast, efficient and safe performance in the data communication process. Large and complex databases all interconnected must be able to receive and transmit data without outside interferences. Fiber optic components are the right solution for complex systems.In order to achieve accurate and precise connections of the fiber ends, very high quality ceramic components are used. Fiber optic connectors made with precision and high quality ceramic components provide a high reliability connection when used with the various adapters.

FIBER OPTIC CONNECTOR TYPES

SC-SIMPLE CONNECTOR : In this simple connecter types there are two types of SC connecters.

SIMPLE & DUPLEX CONNECTERS

Figure 1

Figure 2

Technical data : Housing material: Plastic (UL 94V-0)

Ferrule: Ceramic

Temperature range: - 40°C to +80°C

Mating cycles: 1000

Set with cable boot for cable Ø 0.9 mm

Dust caps

Fig1-single mode

Fig 2-Duplex mode

A push-on, pull-off type of multimode or single mode connector with a ceramic ferrule and an SFF design a simplex or a duplex plastic housing,often used for LANs and data communication.

SPECIAL FEATURES OF LC CONNECTORS

Flame resistant.

Simplified plugs and receptacles.

Three types of duplex SC connector : Flexible F type

Rigid F type

Rigid H type

IEC,JIS,standard comliant and intermateability test certified.

FC :FIBER CONNECTOR

Figure 3

Technical data : Housing material: Metal, Nickel plated

Ferrule: Ceramic

Temperature range: -40°C to +80°C

Mating cycles: 1000

Set with cable boot for cable Ø 0,9 mm

Dust caps

A screw on metallic connector with a ceramic ferrule;

widely used with single mode fiber for active device termination and in high – vibration environment.

ST CONNECTOR : STRAIGHT TIP CONNECTOR

Figure 4

Technical data : Housing material: Metal Nickel plated

Ferrule: Ceramic

Temperature range: -40°C to +80°C

Mating cycles: 500

Set with cable boot for cable Ø 0,9 mm

Dust caps

A slotted bayonet (push in, twist out) type of metallic multimode or single mode fiber connector with a ceramic ferrule.

Widely use in inter / intra building,data communication and also telecommunication application.

LC : LUCENT CONNECTOR

This connecter also have a two types, simple and duplex

Figure 5 – Single mode

Figure 6 – Duplex mode

A push on ,pull off,multimode or single mode fiber type of connector containing a standard RJ 45 telephone plug housing with a ceramic ferrule in a simplex or duplex plastic housing.SFF and SFP designs are sutable for high density interconnection and also usual for instrumentation and test equipment interconnections.

Special advantages of LC connectors:

Doubles fiber dencity in shelves and outlets-lowering system cost

Allows easy disengagement in dense space

Assures high repeatability,maintains transmit/recive direction

Helps minimize transmission problems

Improves durability and reduces connect earrangement effort

Reduce installation time for field mountable connectors

5.MU CONNECTOR :

Figure 7

Mu connectors are basically made by fiber connector with plastic housing and ceramic ferrule.SFF and SFP designs with packaging density that grateter than the SC connector and also smaller. .

These connectors are widely use useful for board-mounted applications and high density interconnections.

Special advantages of MU connectors:

Smooth transition from the FC

Higher packaging density

Excellent performance

Wide application range

Enough EMI protection

6.MTRJ CONNECTOR : MT FERRULE REGISTER JACKLATCH

Figure 8

MT-RJ connectors is a small form factor connecter that was designed to meet fiber optic monolithic ferrule plastic composite. This connecter much like the copper RJ-45 jack.

This connector widely use for both local and metropolitan area networks,particulary with high density interconnection.

Special advantages of MT-RJ connectors

Fiber protection,the connector crimp on mechanism shall protect the bare fibers from the air or waterborne contaminants and shall secure the fibers in the ferrule micro holes.

The connector shall have a latching mechanism to hold the connector into the adapter.

The connector shall not require index matching material between connecter endfaces.

7. 3M TM VOLITION FIBER OPTIC CONNECTOR

Figure 9

Basically this cable contains two parts. Horizontal and Backbone cable.the horizontal cable provides the phhsical link between the fiber connector patch panel in the floor distributor and the fiber connecter in the outlet. Both unitube and tight buffer fiber cables are available and jacket can be PE for outdoor.

Special advantages of 3M TM VOLITION FIBER OPTIC Connector

Minimizing weight and eases cable installation

Complete range of cable

Fast and accurate fiber idenfication

No small loose parts.

Fast easy installation

Excellent pull out strength

Designed to eliminate the need io touch bare fiber

One of the industry leaders in mechanical and optical performance

Light rodent protection.

8. EC2000 CONNECTOR

Figure 10

This connector mostly preferred for single mode fiber oparetion and also exhibits a push-pull latching mechanism, and integrates a protective cap over the ferrule, which acts as a dust shield and shields users from laser emissions. The protective cap is loaded with an integrated spring to ensure proper closing of the cap.

SFF and SFP designs similar to the SC type but also contains an eye protection safety cover built the end face.

9. MTP CONNECTOR : MULTIPLE TERMINATION PUSH-PULL LATCH

Figure 11

These type of connectors for multifiber ribbon cable based on multiple MT-RJ connecters in plastic housing. The same style of monolithic ferrule provides a basis for other connectors. This connectors provide an intuitive push-pull latching mechanism for easy insertion.

This connectors used for high density inter connections.

10. MPO CONNECTOR

Figure 12

The MPO connector houses an MT ferrule, and so can provide for upwards of twelve fibers in a single connector. Like an MPO connectors operate with a simple push-pull latching mechanism and intuitive insertion.

MPO application: Patch cords and Fan-Out assemblies

ATM and DWDM high speed communication systems

Multimedia

CATV and Video

Data Telecommunication Networks

Industrial

11. SMC CONNECTOR

Figure 13

Smc connectors easily terminate buffered or non-buffered ribbon fiber. This connecter has been submitted for review as an industry standard connector.SMC has three different body lengths available, depending on size considerations. The plastic moulded body uses side-mounted locking clips to hold the connector in place.
