HUACHENG Single-Mode G.655 Large Effective Area Fiber Series

HUACHENG G.655 Fiber has large effective area. The fiber is suitable for application of high output power Erbium Doped Fibre Amplifier (EDFA) and multi-channel Dense Wavelength Division Multiplex (DWDM), and can be effectively applied in the high bit-rate both single-and multi-channel, long distance digital transmission links even without dispersion compensation.

Characteristics

Being applicable in the high bit-rate operation across 1530-1565 nm and 1565-1625 nm band
Large effective area ensures good economic return from the transmission system
Low attenuation, low dispersion, low PMD and low zero dispersion slope that satisfy the demand of transmission links
Low bending induced loss at 1550 nm and at the moresensitive 1625 nm wavelength
HUACHENG G.655 Fiber complies with or exceeds the ITU-T G.655.C/D recommendation and IEC-60793-2-50 B4.c/d Optical Fiber Specification.
