Description

Yeesun fiber optic (Large Effective Area High Capacity Positive Dispersion Shifted Single-mode Fiber) is comprehensively optimized for attenuation and dispersion performance at the 1550 nm operating wavelength. The fiber has the lowest attenuation and moderate dispersion at 1550 nm, which enables excellent performance in multi-channel Dense Wavelength Division Multiplex (DWDM) systems traditionally operating in the C-band (1530 nm -1565 nm), as well as in emerging L-band (1565 nm -1625 nm) systems.

Applications

ZTO fibre is the commercialized fibre that has the largest effective area in the G.655 series. The fibre 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

Standard

Yeesun fibre complies with or exceeds the ITU-T G.655.C/D recommendation and IEC-60793-2-50 B4.c/d Optical Fibre Specification
Yeesun tightens many parameters of fibre products so as to offer more conveniences to customers
