Optical Multiservice Edge 6130 NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
Dispersion limited distance (see Note 7 ) see Note 5 see Note 6
Attenuation limited distance (see Note 7 ) see Note 5 see Note 6
Note 1: All parameter values in the above table achieve an optical system BER better than
1x10
-12
.
Note 2: Parameter values for SX SFP are characterized for 62.5 um 160 MHz-km MMF.
Note 3:
The maximum transmit power is the lesser of Class 1 safety limits (CDRH and EN
60825) or the receiver overload.
Note 4: Nominal reach figures are for classification purposes only as defined in the
appropriate standards.
Note 5: 2 m to 220 nm over 62.5 um core, 160 MHz-km MMF; 2 m to 550 m over 50 um
core, 500 MHz-km MMF.
Note 6:
2 m to 10 km over 10 um core SMF; 2 m to 550 m over MMF.
Note 7: The dispersion and attenuation limited distances are based on the dispersion and
attenuation coefficients detailed in Table 7-22 on page 7-23 and are for guidance only and
must be verified by a full link budget calculation. The actual limiting distance is the lower of
the dispersion limited or attenuation limited distances.
