The new material has been subject to the Taber abrasion test (which measures changes in the thickness, weight and optical dispersion of a sample placed against a rotating abrasion wheel), where it shows superior performance to a standard ribbon even after five times more rotations (as illustrated).
ZTE successfully transmitted the signal over a long distance in standard single mode fibre without optical dispersion compensation, setting a world first for the coherent detection of an OFDM optical signal, and laying a solid foundation for the long-distance transmission and coherent detection of OFDM signals.

The diffractive surface features a negative optical dispersion, which yields color correction and minimized chromatic aberration.
Coherent detection with polarization-multiplexed DQPSK technology improves receiver sensitivity and compensates for optical dispersion, resulting in superior cost savings and optical performance when migrating 40G and 100G networks.
The 23 peer-reviewed papers address challenges in material fabrication for engineering light localization, optical dispersion, and plasmonic fields in complex optical media.
The products reportedly include a dynamically tunable laser, either a PIN or an APD receiver and optical dispersion compensation techniques, and are designed for metro and long haul DWDM networks, with dispersion reach of 80 to over 350 km.
Cohesive powders are dispersed using compressed air through an optical dispersion unit and the instrument is supplied with a simple yet, sophisticated Windows-based software package.
Further, since monochromatic light is used for the measurement, optical dispersion is not a problem with the coupler.
Now, with the purchase of a new optical dispersion analyzer from Flow Vision Inc.
It also extends optical links up to 120km without costly optical dispersion compensation, improving link margin in excess of 3dB.
