Here is small instruction for decoding labels on Fibre Channel cables.

Fibre Channel cable decode example: 800-M5E-SN-I – 8 Gb/s cable, multimode OM3 optics, short wave, limited to 2 km.

Fibre Channel label format: 800-M5E-SN-I – Speed-Transmission Media-Transceiver type-Distance

Speed:
1200 – 1200 MB/s
800 – 800 MB/s
400 – 400 MB/s
200 – 200 MB/s
100 – 100 MB/s


Transmission Media:
SM – single mode optics (OS1, OS2)
M5 – multimode 50 nm. optics (OM2)
M5E – multimode 50 nm. optics (OM3)
M6 – multimode 62.5 nm. optics (OM1)
SE –unbalanced copper
DF – balanced copper


Transceiver type:
LC – gamma long wave laser cost reduced (1310nm) with limiting opt. reciever
SN – gamma short wave laser (850nm) with limiting opt. reciever
EL – any electrical point except EA delta point – non equalizing
EA – any electrical point that assumes equalizing reference reciever
LL – gamma point long wave laser (1310/1550nm) assuming a limiting opt. reciever
SA – gamma point short wave laser (850nm) assuming a linear opt. reciever
LA – gamma point long wave laser (1310/1550nm) assuming a linear opt. reciever


Distance:
V – very long distance (up to 50km)
L – long distance (up to 10km)
M – medium distance (up to 4km)
I – intermediate distance (up to 2km)
S – short distance (up to 70m)
