描述
The tight buffer positioned in center of cable. With parallel steel strength member at each side. The cable was struded with black or colored LSZH jacket.
FIRSTFIBER TECHNOLOGIES DROP CABLE 1C G.657A1 SM LSZH ****M printed on cable
特征
– Unique bend intensive fiber makes for more widely bandwidth and stronger data transmitting
– Paralle steel strength member for better strength tensile and protecting the fiber
– Simple cable design,light weight and useful
– special tube filling compound ensure a critical protection of fiber
– Single steel wire or stranded steel wires together with the strength member, ensure good tensile properties of the fiber cable
– Unique groove design, easy stripping, good for junction, installation and protection
– LSZH cable jacket of environmental friendly
