Optical Fiber & Fiber Patch Cables, Single Mode Optical Fiber
Dispersion unshifted single-mode optical fiber is suitable for wavelengths of 1260nm to 1625nm. It maintains the low dispersion of 1310nm in the traditional band and low loss at 1383nm, which makes full use of the E-band (1360nm ~ 1460nm), and improves the macro-bend resistance of the L-band (1565-1625nm), reducing the bend loss at 1625nm wavelength.
Characteristics
- Satisfied and superior to the technical requirement of ITU-T G.652.D & IEC B1.3;
- Suitable for 1260 ~ 1625nm full-band transmission;
- Excellent optical performance can meet the transmission requirements of high-efficiency DWDM and CWDM systems;
- Excellent PMD coefficient meets the long and middle distance and high efficiency of the transmission system;
- Excellent geometry, reduce weld losses, improving performance;
Application
Applicable to the following optical cable structures: central-tube fiber optical cable, stranded loose tube fiber optical cable, slotted core fiber optical cable, ADSS fiber optical cable, etc.
