Optical Bare Fiber Application
Due to the excellent attenuation and bending resistance of low-loss bend-insensitive single-mode fiber, it can be fully compatible with different cabling systems in different installation environments in backbone networks, metropolitan area networks, access networks, and indoors.
Product Standard
Low-loss bend-insensitive single-mode fiber meets or exceeds ITU-T recommended G.652.D/G.657A1 fiber specification and IEC 60793-2-50
B1.3/B6.a1 type optical fiber specification.
Product Features
- Excellent bending resistance and low loss performance
- Realize the transmission of 1260nm~1625nm full band, which improves the system transmission capacity
- Low attenuation to meet the needs of long-distance transmission
- In the case of small radius bending, the fiber can suppress the bending loss well
- Precise geometric parameters ensure low splice loss and high splice efficiency
