描述
The indoor fiber optic cable is made by evenly applying strands of Aramid yarns or High strength glass yarns as the strength member over ф900μm or ф600μm tight buffer fibers and then is completed with PVC(LSZH)jacket.
特征
– Small diameter, light weight,flame retardant,excellent strippability
– Low-attenuation,High flexibility
– No need for transition connector box or pigtail between tight buffer fiber and cable,low cost with installation cause to it’s no needs to clean the water-proofing ointment.
标准
– YD/T1258.2-2009
– ICEA-596
– GR-409
– IEC794
– the requirements of UL approval for OFNR and OFNP.
