What are the optical cables used in indoor computer room wiring?

　　The main types of optical cables used in indoor computer room wiring are as follows:

　　Single-core, dual-core interconnection indoor fiber optic cable (Interconnect cable)

　　Structural features: the tight sleeve structure and high load aramid yarn are used to surround the tight sleeve fiber, which has SMall structure size, good softness and can withstand a small bending radius.

　　Application scenarios: It is suitable for applications such as fiber optic to workstations, communication cabinet interconnect cables, pigtail, jumpers, etc. It is also suitable for applications such as communication cabinets to indoor wall outgoing ends, and outgoing ends to transceivers.

　　Vertical lifting cable (Riser)

　　Structural features: Designed to withstand greater tensile force (maximum weight).

　　Application scenarios: It is mainly used to provide the connection between the entrance equipment, equipment room or computer room and the communication cabinets on different floors after the optical cable enters the building, that is, the "vertical wiring system". At this time, the wiring optical cable is mostly located in the vertical pipe (Riser) of the shaft between floors.

　　fiber optic cable for inflatable environment (Plenum)

　　Structural features: The tight sleeve is made of PVC material, and the outer sheath material is UL-certified PVC material with flame retardant added or hard fluoropolymer.

　　Application scenarios: When the cable needs to pass through the pipeline, high-pressure inflatable space or air handling system to transmit information, the Plenum grade indoor cable needs to be used. This special use environment places more stringent requirements on the flame retardancy and corrosion resistance of the cable.

　　rodent-proof optical cable

　　Structural features: single-core or multi-core tight-sleeved fiber optic cable protected by stainless steel hose has the characteristics of strong resistance to side pressure, bending resistance, high tensile strength, and excellent anti-mouse performance.

　　Application scenarios: It can be used in situations where trampling occurs, such as under carpet laying or where limited space requires frequent bending or rodent infestation.

　　In addition, according to the "Data Center Telecommunications Infrastructure Standards" and TIA approved by the American National Standards Institute According to the provisions of 942-2005, OM1, OM2, OM3, OM4 and other multi-mode fibers and single-mode fibers can also be considered in the wiring of the computer room. Among them, OM3 optical cable (10 megabyte multi-mode optical cable) and OS1 optical cable (single-mode optical cable) are often laid in the MDA area, HDA area and EDA area at the same time due to the advantages of construction difficulty and transmission performance.

　　In general, there are various types of optical cables used in indoor computer room wiring, and the specific type of optical cable selected depends on factors such as the actual needs of the computer room, the wiring environment, and the budget.
