7-28 Technical specifications
Optical Multiservice Edge 6130 NT6Q92MA Rel 1.0 Iss 1 Standard September 2006
Table 7-26 lists the optical specifications for the STM-1/4 CWDM optical
SFPs.
Dispersion limited distance (see Note 4 ) 12.3 km
Attenuation limited distance (see Note 4 ) 34.3 km
Note 1: All parameter values in the above table achieve an optical system BER
better than 1x10
-10
when used over G.652 specified SMF-28 fiber.
Note 2: Power monitor accuracy figures are for normal operating range (minimum
to maximum transmit power, receiver sensitivity to overload).
Note 3:
Nominal reach figures are for classification purposes only as defined in the
appropriate standards.
Note 4: 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.
