This optimisation is critical when dynamic network reconfiguration is required to reroute optical channels
for capacity reallocation or node failover onto alternate routes.
With the O-OFDM switching technology, one can dynamically change the number of subcarriers on each optical channel
and/or adjust the modulation format of each subcarrier while still meeting the total link capacity requirement.
As shown in the figure, a module called central optical channel
manager (COCM) is placed near the entrance of waveguides.
--an optical channel
which comprises a digital laser telemeter connected to the portable computer- meant to measure and fix the required distance between radiation source and video spectrometer as well as to centre the optical axis of spectrometer on the source of spectral radiation using the targeting of maximum emission area with red beam of laser radiation
A single optical channel
point-to-point terahertz transmitter and receiver are shown in Figure 1.
Metro One significantly broadens the applications for optical networking in the metropolitan area because it is designed for locations where a single optical channel
needs to be dropped, such as a business customer site.
However, TDM can complement WDM by interleaving the bits of several lower-speed signals onto a single high-speed optical channel
. To mine terahertz bandwidths, both WDM and TDM schemes must be used.
Figure 5 shows the discrete time simulation result of normalized time domain CIR of the diffused optical channel
[h.sub.n] for channel delay spread of 10 ns and 20 ns.

part) of Dual polarization OFDM system.
The input of stage-1 optical channel
dropping filter (OCDF) is dark soliton (logic "0") which is a control light pulse.
Random noise-like error model is widely used to model optical channel
. The channel statistics of an optical channel
is often described by BER.
The DLC156 enables up to six uncompressed HD-SDI or three 3G-SDI signals to be transported over an optical channel
. Available in 1310nm, 1550nm, CWDM or DWDM wavelengths users can transport up to one-hundred-twenty 3G-SDI, two-hundred-forty HD-SDI, nine-hundred-sixty 270Mb/s video services, or in combination over a single strand of fiber.
