The common problem of the Generic Cabling System:
1What is the Generic cabling System?
The Generic cabling System is that one is used in the voice, data, image and other information technologies standard structurization cabling system. It is the transmission network of building or buildings. It can make the voice and data communications equipment (DCE), exchanger equipment and other information management systems link to each other. It is compared with traditional cabling system, there is a lot of superiority. It has compatibility, opening, flexibility in it that its main characteristic displays, dependability, advanced and economy.
2Does Generic Cabling System divided into several parts mainly?
The Generic cabling System can be divided into six subsystems: Workspace subsystem, horizontal subsystem, vertical arterial subsystem, equipmentroom subsystem, management subsystem and buildings subsystem.
3Which are the standards of Generic Cabling?
Popular in the world there are two standards mainly:
One standard TIA/EIA568A/B of North America [commercial building telecommunication cabling standard, define relevant norms of Generic Cabling design, equipment , and parts, and the installation and test of Cat.5 of transmission performance . Release a whole standard one brand-new augment editions of TIA/EIA568B , it puts all change and TSB of influence A edition merge into in 2000, and recommend using Cat.5e]
One international standard 11801 ISO/IEC [this standard propose Generic Cabling structure , scale , part transmit performance define, the regulations in installation and test standardize]
--TIA/ EIA-568A commercial building telecommunications cabling standard (Canada adopts CSA T529)
--EIA/ TIA-569 telecommunication passway and commercial building of the space standard (CSA T530 )
--EIA/ TIA-570 house and N type commercial telecommunication cabling standard ( CSA T525 )
-- TIA/ EIA-606 commercial building telecommunication infrastructure of management standard (CSA T528 )
-- TIA/EIA-607 commercial building earth /join requiring (CSA T527)
--IEEE802.3-1990 signal carrier measure many location link / conflict is it visit method and physics layers of norm ANSI/IEEE 802.3-1990 standard and ISO 8802-3:1990E to measure
--IEEE 802.5-1989 IBM visit method and norms of physics layer (namely ANSI/IEEE standard 802.5-1989 )
Domestic relevant standards:
--" the building and buildings generic cabling system engineering design specification " (GB/T 50311-2000)
--" the building and norm of acceptance of work of generic cabling system of buildings " (GB/T 50312-2000)
--" building , buildings generic cabling system engineering design and norm of confirming " CECS72: 97
Other relevant standards:
--AWG(American Wire Gauge): Measure the American wire gage of the diameter of the wire --TSB568A/B: The schemes of wiring of module socket and plug
Common problem about Cat.6 cabling products:
1Which questions should pay attention to choose Cat.6 cabling products? Cat.6 cabling products should pay attention to 8 elements:
(1) Real Cat.6 system should from connector, cable to the link and channel all satisfied with Cat.6 performance demands, include the Keystone Jack ,Patch Panel , Patch Cord, and cable etc. parts;
(2) It must be a worst situation model defined in TIA/ISO standard that was adopted in the submitted systematic test report, namely 3 connection pieces of 90 chain or 4 connection pieces of 100 channel;
(3) The manufacturer should offer the overall test data in Cat.6 of products and bandwidth below 250MHz of system , and can stand carrying on a contrast with Cat.6 ISO/TIA standard require of parameter and index ;
(4) The test result about frequency of some characteristics can't represent the performance inside of the full test bandwidth . The manufacturer should also offer some test results of (except domestic) third party and official organization ;
(5) The products are ripe, already commercialization, has had project application of Cat.6 systems ;
(6) The producer can offer Cat.6 products of all fronts , is suitable for user's diversified choice, meet user any installation method and dispose requiring;
(7) Users can demand to use the on-the-spot tester to carry on on-the-spot test to the link or channel that the manufacturer submited according to the international standard , it sees to whether can content the Cat.6 index or not;
(8)The manufacturer should offer the integrating trader to specially train for Cat.6 installation , and the integrating trader only after this training can participate in the installation and construction of Cat.6 projects (users can demand to show this kind of certificate of vocational training in the integrating trader ).
2Which questions should Cat.6 Cabling be paid attention to while constructing?
(1) Because the diameter of Cat.6 cables thicker than Cat.5 cables, (especially in the bend head) for prevent cable from twine, should pay attention to the packing degree of pipe diameter in the pipeline design, the line of the general internal diameter 20mm is in order to put 2 pieces of Cat.6 cables.
(2) The bridge shelf design is reasonabl e , guarantee the suitable crooked radius of cable.
(3) Put line course pay attention to control on pulling force mainly .
(4) After drawing the line process, the redundant cable that both ends reserve should be put in order and protected well, it want it is which obey original rotation at the time of records of line to, coil diameter is don't the getting lighter too, probably, with abolishing there aren't end of a thread, do well and mark, remind other personnel to step on without moving.
(5)In put in order , ligature, at placing the cable, the redundant cable don't be too long, don't let the cable superpose , the coil takes advantage of a situation to check and regulate, don't be tied too tight while pitching the rope regularly.
(6) During the whole constructing , the technological process notify in time , various kinds of project directors about the building should communicate in time, pinpointing the problems will notify Party A at once , will finish a work post task in time before other follow-up work posts will begin.
