The DCU board compensates for the dispersion that is accumulated in
the fiber during transmission and compresses optical signal pulse.
This enables the transmitted optical signals to be restored at the
output end. In addition, when used together with an optical
amplifier board, the DCU board can implement long haul optical
transmission.
For detailed functions and features, refer to Table 1.
Table 1 Functions and features of the DCU board
Function and Feature
Description
Basic function
Provides dispersion compensation for different transmission
distance.
Dispersion compensation method
Compensates for the dispersion accumulated in an optical
transmission system, and compresses the optical signal pulse. This
enables the transmitted optical signals to be restored at the
output end.
Long haul transmission with optical regeneration
Implements long haul transmission when used together with an
optical amplifier board.
Optical-layer ASON
Supported
Characteristic Code for the DCU
The characteristic code for the DCU board contains characters,
indicating the type of the fiber that the board works with and the
dispersion compensation distance.
The detailed information about the characteristic code is given in
Table 1.

Description
Character before hyphen (-)
Fiber type
Type of the fiber that the DCU board works with
Character after hyphen (-)
Dispersion compensation distance
The transmission distance achieved through dispersion compensation
For example, the characteristic code for the TN11DCU board is
G.655LEAF-40. It indicates that the DCU board works with G.655LEAF
fibers, and the dispersion compensation distance is 40 km.
NOTE:
If the characteristic code contains various dispersion compensation
distances, the symbol "&" is used to separate each distance.
DCU Specifications
Specifications include optical specifications, dimensions, weight,
and power consumption.
NOTE:
A margin of the lower threshold of input optical power compared
with the receiver sensitivity of the board and a margin of the
upper threshold of output optical power compared with the overload
point of the board are reserved on the U2000 as a precaution.
