摘要: Optical fibers having a mode field diameter at 1310 nm of least 8.8 μm, wire mesh covered drum microbending losses 1550 less than 0.03 dB/km, and 2 m cutoff wavelength 1320 nm. The may include central core region, an inner cladding outer primary coating with in situ modulus 0.20 MPa glass transition temperature −35° C., secondary greater 1500 MPa. further depressed index region. relative refractive the region be produced draw speeds 30 m/s or greater.
