Features
· Good mechanical and environmental characteristics;
· The strippability characteristics of buuer meet the relevant standards or customer requirements;
· Meet various requirements of market and clients.
Application
· Tight-buuered fiber is the basic element of various indoor cabies. Because of diuerent buuer materials, the relevant indoor cables made out of tight-buuered fibers can meet diuerent mechianical and environmental requirements, forexample, large tensile(crush), high or low temperature, frequent bends, low smoke , nocorrosive, environmental, field use, distribution cabinet(frame) and other generic use, etc;
· Tight-buuered fibers with various buuer material can also be used in pigtails, optical connections of various optical active and passive devices, instruments and terminal units.
Options
· Fiber Type: G.652, G.655, G.657 single-mode fiber, A1a or A1b mulit-mode fiber, or other types of fiber;
· Material of buuer: Flame-retardant poly vinylchlo- ride(PVC), low smoke zero halogen flame retardant polyolefin(LSZH), Thermoplastic Polyester Ester Elastomers(Hytrel), or other contracted material;
· Color of buuer: blue, orange, green, brown, gray, white, red, black, yellow, violet, pink, turquoise, or other contracted dimension;
· Outer diameter of fiber: The nominal diameters are 0.580mm and 0.880mm, or other contracted length.
· Delivery Length: 1KM or 2KM or other contracted length;
Other Requirements: Other contracted special requests
