1R
|
|
|
|
– |
Equal
amplification of all frequencies within the amplification
|
|
|
bandwidth.
There is no restriction upon information formats.
|
|
|
– |
Amplification
with different gain for frequencies within the
|
|
|
amplification
bandwidth. This could be applied to both single-
|
|
|
channel
and multi-channel systems.
|
|
|
|
– |
Dispersion
compensation (phase distortion). This analogue process
|
|
can
be applied in either single-channel or multi-channel systems.

2R
(any or all 1R functions plus:)
|
|
|
|
– |
Digital
reshaping (Schmitt Trigger function) with no clock
|
|
|
recovery.
This is applicable to individual channels and can be used
|
|
|
for
different bit rates but is not transparent to line coding
|
|
|
(modulation).
|
|
|
| • |
3R
(any or all 1R and 2R functions plus:)
|
|
|
|
– |
Complete
regeneration of the pulse shape including clock recovery
|
|
and
retiming within required jitter limits.
