Background

Based on evaluation method presented in May, (wang_t_3bs_01_0514), FEC
performance with different burst error factors are explored; BERin requirements are listed for
reference.

KR4/KP4 FEC performance with all muxing methods are explored for comparison.

Updates in Calculation

For FEC incorporated 400GbE, FLR(frame loss rate) is more
practical in evaluating MTTFPA performance. So we also use FLR
equations from BER,

Effect of Parameters

b: “Prob of continuous error after a initial error bit”


Rllmax : “maximum burst error length”


Smaller value of b, less probability for burst errors
Larger rllmax increases probability for burst errors
Example with FOM bit mux 2:1 With different value of b and rllmax
FOM bitmux with b=0.5/0.1, rll=17/4

Performance Difference - 1x400GbE vs. 4x100GbE

While 400GbE has four parallel 100GBase-KR4/KP4 RSFEC and FOM mux
options, if every individual 100GbE reuse one RSFEC encoder/decoder with
only non-FOM mux options, what is the performance for 100GbE?

Mux options:

Bit mux

To reach BERpost = 1e-13 in 400GbE, SNR = 12.2dB,
On each 100GbE,
BERpost = 1e-10 (b=0.5, rll=4);
= 5e-11 (b=0.1, rll=4)
*MTTFPA = 108 ~ 1010 years.

Conclusions

By using 100GBASE-KR4 RS(528,514) and FOM bit mux 2:1, BERin should be
1.9e-5 to satisfy BERpost = 1e-13 objective in 400GbE, with coding gain of
5dB;

By using 100GBASE-KP4 RS(544,514) and FOM bit mux 2:1, It requires 2.8e-4
to meet BERpost = 1e-13 objective in 400GbE, with coding gain of 6.5dB;

Supporting 400GbE and 4x100GbE compatible gearbox is possible with
bitmux option, either accepting a certain degradation of performance
according to the PMD features or we can put constraints on error
propagation factors to keep MTTFPA.
