The cabling system proposed is fully compliant to the industrial cabling standard EIA/TIA568. The performance  specifications are based on Enhanced Category-5e or Category-6 UTP cable. Thus the implemented cable system shall be able to support the required 100Mbps or Gigabit Ethernet networks.
The cable system is also capable of supporting voice (telephone and fax), ISDN, 10/100/1000Mbps Ethernet, 16Mbps Token-Ring, multimedia and mini-computer transmission services. All services are available via the centralized patching system.
ZHAOSHI-SYSTEM's cabling system service portfolio consists of:
- Summary of the Cabling System
- Cabling System Design Services
- Cabling System Installation Services
- Cabling System Testing & Certification Servic
I. Summary of the Cabling System
For the Client’s cabling system, the indoor network cabling infrastructure, the 4-pair Category 5e non-plenum unshielded twisted pair (UTP) is recommended. It supports all network topology like the widely used 10Mbps Ethernet, 100Mbps fast Ethernet, and Gigabit Ethernet.
The Six Subsystems of a Structured Cabling System are as follows:
1. Building Entrance
2. Equipment Room
3. Backbone Cabling
4. Telecommunication Closet
5. Horizontal Cabling
6. Work Area
For the Client’s cabling systems, the subsystems shall be applied. There are work area subsystems, horizontal cabling subsystem, telecommunication closet and equipment room subsystem.
II. Cabling System Design Services
ZHAOSHI-SYSTEM shall deliver the following design services:
- Physical wiring topology and device location map
- Voice/Data patch panel service assignment tables
- Cable Trunking routing map
- Telecom closet layout map and computer room layout map
Cable tray/trunking routing system design
We have had experiences working with local design institutions, building contractors and interior decoration companies in the design of cable tray/trunking routing systems for new as well as refurbished existing building.
Supervise the construction of the cable tray/trunking system
Supply and install the specified cable tray/trunking routing systems.
III. Cabling System Installation Services
Implement the cable system, which includes pulling of cables to the information outlets, terminating the cable ends and installing the patch panel systems.
Install the intended services for each information outlet
Install the concentrator and all its associated modules. The intended services (telephone, fax, Ethernet, and etc.) for each information outlet is also shall be installed.
IV. Cabling System Testing & Certification Service
There are two test and certification processes: the first is to certify the installed cable system against EIA/TIA-568 specifications; the second is to test and certify the provision of intended services at each information outlets.
The former is carried out with cable testers. Testing shall be performed are wire-pair matching, length test, attenuation test, and Near End Cross Talk (NEXT). All frequency domain tests are performed in compliance to the EIA/TIA-568 Category-5e and TSB-67 specifications
The tests are carried out at each outlet. A signal generator is placed at one end of the cable and the cable tester at the other end. The cable tester than cycle through a pre-defined test sequence at specific frequency points.
ZHAOSHI-SYSTEM will provide a detailed on-line printout of performance data for each labelled information outlet.
The second process involves working with the service providers (for example, the vendor installing the PBX system) to confirm the intended services at each outlet. Actual end-user equipment may by used, as well as advanced LAN meter (which is able to emulate Ethernet and Token-Ring stations) for testing network connections.
A service assignment report (indicating the services assigned to each labelled outlet) will be provided at the end of the tests. |
