7XV5461-0Bx00
Reach 100 km:
– Path attenuation
– Optical wave length
Transmitting power coupled in singlemode fibre
Receiver sensitivity
Optical Power Budget
When using the 60-km device model for transmission links < 50 km, two attenuators must
be connected to the end of the remote connection (see chapters Connection Notes and
Installation Notes).
Reach 170 km:
– Path attenuation
– Optical wave length
Transmitting power coupled in singlemode fibre
Receiver sensitivity
Optical Power Budget
When using two 170 km device variants for transmission distances that are less than
100 km, both delivered attenuators must be connect to the end of the remote connection (Rx
and Tx) on one of the devices (see chapters Connection Notes and Installation Notes).
Note: One attenuator is delivered pro 170 km device variant.

Caution!
For transmission links < 100 km, connecting the two attenuators to the
end of remote connection is required as the optical receivers may be
damaged otherwise.
With singlemode fibre, the light of the
wave length λ = 1550 nm is anticipated with
an optical signal attenuation of 0.22 dB/km.
