• The horizontal cabling shall be star-wired.

• The maximum horizontal distance shall be 90Mtr. between the outlet and the patch panel (excluding patch cords and line cords).

• The horizontal cabling shall be free of taps and bridges.

• One cable shall be strictly used for one application, cable sharing will not be acceptable.

Connecting Hardware for Horizontal Cable:

Connecting hardware shall be based on shielded RJ45 interface. The hardware shall feature excellent transmission performance and mechanical strength. Integral wire management and cable strain relief shall be integrated into the hardware. It should be possible to use the same RJ45 interface module at the outlet end as well as the patch panel (IDT) end. Termination of the cables on the hardware shall be accomplished without the use of any tools i.e. tools free installation. The termination at the patch panel end should cater to grounding of the panels using separate earthing facilities. The patch panels should consist of earthing kits to enable this grounding of shielded cabling.

Wherever single RJ45 outlet is used, it should be possible to easily upgrade to dual RJ45, without any major changes to the faceplate. The Screened RJ45 will have the following specification:-

- Comply with the latest standard proposals of ISO/IEC and EIA/TIA for Cat 6 requirements.

- Compatible with Category 6 Generic standard plugs.

- Tool-free connection technique (IDC) for data cables with AWG 23-26 wire diameter.

- Allows opto-mechanical control of the connection technique.

- Error-free connection according to EIA/TIA 568A/B/C without pair crossover.

- Patented shield contacting with integrated cable strain relief.

- Halogen-free material.

- SGS, UL, CSA certified.

RJ45 Hardware Electrical Characterization, Transmission performances:

Worst Pair Combination with a Cat.6 Plug

Patch Cords & Line Cords:

The patch cords and line cords shall constitute of two modular RJ45 plugs assembled on shielded twisted pair stranded cable. The SSTP stranded cable shall be constructed using flexible cable . The sum length of all patch cords & line cords for one outlet shall not exceed 10Mtr. Under no circumstances shall locally assembled patch cords and line cords will be acceptable, all must be factory made.

Connecting Hardware for Voice Backbone Cable:

The voice backbone cables shall be terminated on high density 50 port RJ45 patch panels, which shall be housed in the 19" IDT cabinet. These panels shall accept UTP cables having AWG22-26 solid or stranded wire. Highly visible, colour coded strips shall be used to identify individual pair of the backbone cable. These panels shall have features like gas-tight connection, integral strain relief mechanism.

Data Backbone Cable:

Frequency Attenuation NEXT FEXT RL

[MHz] [dB] [dB] [dB] [dB] [dB] [dB] [dB] [dB]

The backbone cable for data applications shall comprise of fiber optic cables. The cables shall have minimum 8 or 12 cores of Multimode 50 /125 graded index fiber strands. The fiber optic cables shall have the following characteristics:

Wavelength (nm) Max. Attenuation (dB) Bandwidth (MHz x Km)

850 <2.5 >400

1300 <0.7 >1200

If the backbone distance exceeds 550Mtr, single mode fiber cables shall be installed.

These cables when installed, shall have the following characteristics:

Wavelength (nm) Max. Attenuation (dB) Bandwidth (GHz x Km)

The fiber optic (data backbone) cable shall be field terminated with ST connectors (with ceramic ferrule) on each fiber strand. These connectors shall be installed in fiber optic patch panel, mounted in 19" IDT cabinet. These shall feature sliding drawer type panels for better administration of the fiber cables. The panels shall have holes at the rear for inserting and strain-relieving cables with PG glands. Cable and fiber guides for buffer management within the panels shall be built-in the panel. The insertion loss on each SC connectors shall be < 0.2dB.
