Ultra-long-distance ultra-large capacity wavelength division transmission applications

Wavelength division Multiplexing system Optical road Science and technology a small, low-cost, high-speed, large-capacity wavelength division multiplexing transmission system, the number of channels up to 40 waves, With a maximum speed of 10gbit/s and a total capacity of up to 400Gbit, the single wave channel can meet telecom operators ' Super Large capacity and Ultra long distance transmission wdm Wavelength Division multiplexer

1, in large capacity can be used investigate-wave unit (fiber wavelength Division multiplexer), this investigate-wave unit a single channel rate of up to 10G, the total capacity of up to 480g,c+l segment can be expanded to 1600G, effectively meet the new era of large granular business transport, aggregation needs .

As shown, the dense wavelength division multiplexer + High-speed single channel transmission, can realize the ultra-large capacity of the transmission system. Excellent solution to the problem of insufficient capacity.

2. Ultra Long Distance wavelength division transmission System There is a problem that needs to be solved, that is, in the transmission to a certain distance after the light power will become smaller, then how to solve this problem? We can design the scheme--the EDFA erbium-doped fiber amplifier is configured in the relay room throughout the link, which amplifies the weak light signal through the fiber amplifier device, allowing it to transmit farther distances.

As shown in the relay room configuration EDFA fiber amplifier, can not only solve the light signal too small problem, can let him transfer farther distance.

and technicians know that an integral part of the WDM system is DCM dispersion compensator. For example, a 80km the optical module, Even if the power is large, but the transmission distance can only be transmitted 80km , can't transfer 120km or farther, because his waveform has deviated and widened. So you want a Module is required to use the DCM when the optical power is met dispersion compensator. That's how it goes. The widening waveform is re-organized and retransmitted.

DCM dispersion compensator, Can solve the problem of dispersion, integrated above basis, WDM transmission system = wavelength division multiplexer + Multichannel rate otu business board +edfa fiber amplifier dispersion compensator. ultra-long-distance ultra-large capacity WDM transmission system > Let you put it down.
