YOFC G652D Low Water Peak Single-mode Optical Fiber Core Bare Fiber 50.4km
1. What is G652 fiber ?
YOFC low water peak dispersion unshifted Single-mode fiber is designed specially for optical transmission systems operating over the entire wavelength window from 1260 nm to 1625 nm.
By suppressing the water peak that occurs near 1383 nm in conventional single mode fibre due to hydroxyl (OH-) ions absorption, the fibre is able to open E-band (1360-1460nm) for operation, and consequently provides 100 nm more usable wavelengths.
2. Construction:
3. Product standards:
YOFC FullBand® fibre complies with or exceeds the ITU-T Recommendation G.652.D and the IEC 60793-2-50 typeB1.3 Optical Fibre Specification.
YOFC tightens many parameters of fibre products so as to offer more conveniences to customers.
4. G652 Fiber Characterics:
• The G542 Fiber is designed for operation over the full optical spectrum from 1260-1625 nm, which provides 50% more usable wavelengths and hence the transmission capacity is increased.
• Outstanding optical performance supporting high-speed transmission technologies such as DWDM and CWDM
• Being compatible with existing 1310 nm equipment.
• Good protection and excellent strip force stability.
• Accurate geometrical parameters that insure low splicing loss and high splicing efficiency.
