Outdoor FTTH mainly used in duct installation GYFXTZY -2G657A2
Bow-type FTTH put in side with 2 KFRP, the optical fiber unit positioned in the centre. Two parallel strength member are placed at the two sides and have aramid yarn to protect the inside FTTH, ourside sheath is PE.
2.Suitable for aerial and duct drop installation
3.Long distance and local area network communication.
· Anti-UV charateristics meet the requirements of relevant standards
· The mechanical charateristics meet the requirements of relevant standards
· Big capacity data transmission
· Meet various requirements of market and clients
