The availability of the E-band with full spectrum fiber is possible by a new fiber manufacturing process. This increased bandwidth let the full spectrum fiber superior choice for metropolitan and access optical networks. In optical fiber application, the hydrogen aging effect is important factor in the long-term reliability of an optical fiber. In this work, we report a test results for hydrogen aging effect of full spectrum fiber. The attenuations of the fibers are varying even in a hydrogen-free environment after aging test. It is also found that so small bending of full spectrum fiber in hydrogen aging test chamber cause significant variations in optical characteristics.
A laboratory experiment was evaluated on the CWDM/GbE Metro Network System. The system is configuration
with the optical fiber Coarse Wavelength Division Multiplexing (CWDM) devices that are designed for
Metropolitan and Access Area Network. CWDM devices can support 8 channels over a single fiber either
a uni- directional or bi-directional mode, and can increase fiber capacity from 2 to 16 times
transmission capacity. The system performance was evaluated using the network performance analyzer by
measuring the characteristics of throughput and latency. The systems test results showed that this CWDM
based Gigabits Ethernet have good transmission performance through the distance to 50 Km.
