Optical Interfaces/SFPs
STM-1
The table below lists some parameters and the end of life power budgets for the fixed
STM-1 optical interfaces that are supported by the 1643 AM and STM-1 SFP cages
that are supported by the 1643 AMS:
Application
Operating wavelength range
Transmitter at reference point S
Source type
Spectral width at -20 dB (max)
RMS spectral width (max)
Side mode suppression ratio (min)
Mean launched power (max)
Mean launched power (min)
Extinction ratio (min)
Mask of the eye diagram of the
optical transmit signal
Optical path between points S and R
Maximum dispersion
Attenuation range
Minimum optical return loss of the
cable plant at point S including the
optical connector
Receiver at reference point R
Sensitivity (min) at BER = 1 × 10
-10
Overload (min)
Optical path penalty
Optical return loss of the receiver
(min)
Note: 1643 AM STM-1 (Aggregate and tributary) or STM-4 optical access is via an
SC-type connector. Adaptors FC and ST are also supplied.
1643 AMS: All optical interfaces are available as SFPs (Small Form-Factor Pluggable
Optics) for STM-1 transmission only.
Note that the 1643 AM supports S1.1 and L1.2 interfaces for STM-1 transmission,
whereas, the 1643 AMS only supports S1.1, L1.1, and L1.2 SFPs. The 1643 AMS does
not support STM-4 transmission.
