:- Cables :- 1. Co-Axial Cable :- Co-Axial Cable Normally Used in TV. Today In Networking Field Co-Axial Cables Haven’t Used . This Cable Was Come In Starting Of Networking . Features :- 1. Distance 500M To 200M . 2. Data Transfer Rate Upto 10 Mbps . 3. Resistance 100 Ohm . 4. Noise-----Yes . Look :- This Shield Used For Protection From Noise . Types :- 1. Thick RG-32 :- 500 Metre . 2. Thin RG-59 :- 200 Metre . Connectors :- 1. Bnc :- . 2. Aui :- . 3. Tee :- . Today Co-Axial Cable Is Absolute In Market For Networking . 2. Twisted Pair Cable :- After Co-Axial Cable . Twisted Pair Cable Has To Come In Market . This Cable Come Into 2 Pair—22Pair , But In Networking 4 Pair Has To Come In Market . 4 Pair Means :- 4 Pair And 8 Wires Cable Has To Come In Market . Features :- 1. Distance :- 100 Metre . 2. Data Transfer Rate :- 10---100 Mbps . 3. Resistance :- 50-60 Ohm . 4. Noise—Yes . Types :- 1. UTP :- Unshielded Twist Pair . 2. STP :- Shielded Twist Pair . Look :- UTP :- STP :- Connectors :- RJ-45 ( Real Jack / Radio Jack ) 8 Pin Connector . Category :- 1. CAT-4 :- 10 Mbps . 2. CAT-5 :- 100 Mbps . 3. CAT-6 :- 1000 Mbps . Two Types Of Noise :- 1. E.M.I :- (Electromagnetic Interface) When Cable Comes To Close E.M.I . E.M.I Willn’t Allow To Data Reach At That Point OrTarget. Data Willn’t Ahead From E.M.I . So The Result Is Networking May Be Down Or Damage . 2. R.F.I :- (Radio Freguency Interface) Day By Day R.F.I Technology Very Fast Come Into A Market . In Networking Next Two Or Three Year This Technology Has To Come Very Fast . Networking Map May Be Change Wi-Fi Technology Is A Example Of R.F.I Technology . Solutions :- Twisted Reduced R.F.I Features :- Speed 2GHz / 5GHz . 3. OFC Cable :- (Opital Fabric Cable) This Is A Very High Speed Cable . It Works Under Sea . All Types Network Depend On It . It Is Very Costly Cable . Features :- 1. Distance :- In Km . 2. Data Transfer Rate :- 1000 Gbps . 3. Resistance :- Ohm . 4. Noise :- Free . Look :- Midia Convertor :- 1. Upto Coupler :- Laser Diode . 2. Photo Sensor :- Photo Diode . We Have Used Convertor For Sending A Data In Graphic And Text Mode . These Convertor Convert The Data Text As Well As Graphic Mode . Connector Used In OFC :- 1. SC :- (Subscriber Connector) Types Of OFC :- 1. Mono Mode . 2. Multi Mode . Mono Mode :- Mono Mode Is A Single Mode . It Distance 100 Km . It Is A Data Transfer Rate 100 Gbps . Multi Mode :- Multi Mode 1 Lead And 6-7 Core . It Distance And After 10 Km Attach Another Reciver. 2. Repeater . Companies For OFC :- 1. Atnt . 2. Octadel . 3.
