Bi-directional FEC — Improving the Line
Transmission Quality
FEC in the
upstream
direction
FEC in the
downstream
direction
FEC: Forward error correction.
FEC corrects bit errors in the
transmission by adding
verification bits during coding.
What Is FEC?
OLT
ONT
ONT
When is FEC needed?
When the optical power budget is
inadequate or the bit error ratio is
high due to the long distance of ONT
and poor line quality, the FEC is
needed.
After the FEC is enabled, the noise
tolerance of the line is enhanced, but
the bandwidth utilization decreases
by at least 7%.
MA5600T supports the FEC function
in both the upstream direction and
downstream direction.
Enabling or disabling the FEC is
configured on the ONT.
When is FEC not needed?
when the distance of
ONT is short, and the line
quality is good, the FEC
function is disabled for
ensuring the bandwidth
utilization.
The FEC function is supported by GPBD board, and the match ONT is
HG824x series. The optical power budget can increase by 2-3 dB.

Enhanced OPM Precision
±3dB ±1dB
OPM Precision Improved From ± 3dB to ± 1dB
Optical power attenuation (budget)
occupies 85% of the ODN problem 1. ±3dB means that
actually almost 6dB
attenuation can be
detected. But
generally, ODN
power budget is
3dB, if there is a
3~6dB attenuation,
the ONT gets off-
line, not to mention
OPM
2. We can only do
some qualitative
analysis base on
±3dB OPM
1. With ±1dB OPM,
we can detect more
than 95% of the
ODN power
attenuation
problems
2. Replace optical
power meter in
most scenarios
with integrated
OPM, help the
customer doing
quantitative
analysis of ODN
