Structured cabling data voice - project and installation
Luând in considerare necesităţile dumneavoastra concrete, specialistii noştri va pot oferi solutia tehnica optima perfect adaptata cerintelor si conditiilor de lucru din cadrul companiei dumneavoastra. Instalarea unei centrale telefonice impreuna cu o retea date – voce reprezinta o eficientizarea a comunicatiilor in cadrul unei firme.
Punctul de plecare il va reprezenta vizita specialistilor noştri la sediul dumneavoastra , evaluarea conditiilor concrete, realizarea unei schite de proiect si alcatuirea unui deviz estimativ.
Retele structurate voce - date
- Cablarea structurata se va realiza conform standardelor in vigoare pentru retelele structurate cat 5e respective cat6 / cat7. Suportul tehnic este asigurat de specialistii nostri certificati de firmele furnizoare de echipamente.
- Nodul central al retelei il reprezinta dulapul de telecomunicatii in componenta caruia intra : patch paneluri , wire managere , patch – corduri, elemente active.
- Elemente de cablare structurata:
- 1. cablajul orizontal se realizeaza folosind cablu cablu UTP/FTP/STP Cat.5e sau Cat6 / Cat7 pozat plecând de la nivelul rackurilor de telecomunicatie, de-a lungul magistralelor principale si secundare, până la nivelul statiilor de lucru.
- 2. cablajul vertical Pentru realizarea intercomunicarilor intre rack-urile de nivel se pot folosi:
- cablu UTP/FTP/STP Cat 5e sau Cat.6 HALOGEN FREE
- fibra optica
Traseele au ca suport fizic patul de cablu metalic sau canal de cablu din plastic , de dimensiuni corespunzatoare.
- 3. casete si prize
Se pot folosi :
- prize simple/duble aparente sau ingropate, ecranate sau neecranate
- casete de pardoseala cu 6/12 module
Structured cabling standards:
TIA/EIA-568-A-1995 (Commercial Building Telecommunications Wiring Standards) Defines a standard for building cable system for commercial buildings that support data networks, voice, and video. It also defines the technical and performance criteria for cabling.
TIA/EIA-568-A updates (1998-1999) The TIA/EIA-568 was updated several times through this time period. Update A1 outlined propagation delay and delay skew parameters. Update A2 specified miscellaneous changes. Update A3 specified requirements for bundled and hybrid cables. Update A4 defined NEXT and return loss requirements for patch cables. Finally, update A5 defined performance requirements for Enhanced Category 5 (Category 5E).
TIA 568-B.1-2000 (Commercial Building Telecommunications Wiring Standard) The year 2000 update packages all the previous addendums and service updates into a new release and, most important, specifies that Category 5E cable is the preferred cable type that can provide minimum acceptable performance levels. Several addendums were also released that specify technical information for 100-ohm twisted-pair cable, shielded twisted-pair cable, and optical fiber cable.
TIA/EIA-569-A-1995 (Commercial Building Standard for Telecommunications Pathways and Spaces) This standard defines how to build the pathways and spaces for telecommunication media.
TIA 570-A-1998 (Residential and Light Commercial Telecommunications Wiring Standard) This standard specifies residential cabling.
TIA/EIA-606-1994 (Building Infrastructure Administration Standard) This standard defines the design guidelines for managing a telecommunications infrastructure.
TIA/EIA-607-1995 (Grounding and Bonding Requirements) This standard defines grounding and bonding requirements for telecommunications cabling and equipment.
The current trend is to evolve the standards to support high-speed networking such as Gigabit Ethernet and define advanced cable types and connectors such as four-pair Category 6 and Category 7 cable. Category 6 is rated for channel performance up to 200 MHz, while Category 7 is rated up to 600 MHz
