Specification
The fibre is suitable for non-coherent long-haul and metro networks, can be effectively applied in the high bit-rate both single-and multi-channel, long distance digital transmission links even without dispersion compensation.
Product Features
• 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
