2.12.2 Linking to Communication Circuit
The GRL100 can be provided with one of the following interfaces by order type and linked to a
dedicated optical fiber communication circuit or multiplexed communication circuit.
•
Optical interface (1310nm, SM, 30km class)
•
Optical interface (1550nm, DSF(Dispersion Shifted Fibre), 80km class) (*)
•
Optical interface (820nm, GI, 2km class)
•
Electrical interface in accordance with CCITT-G703-1.2.1
•
Electrical interface in accordance with CCITT-G703-1.2.2 and 1.2.3
•
Electrical interface in accordance with CCITT X.21
•
Electrical interface in accordance with RS422, RS530
Note (*): When using the 80km class optical interface, it is necessary to ensure that the received
optical power does not exceed
−
10dB, in order to avoid communication failure due to
overloading of the receive.
When testing in loop-back mode, for instance, the sending terminal should be connected
to the receiving terminal via an optical attenuator with 10 dB or more attenuation.
Even if the sending terminal is directly connected to the receiving terminal, the optical
transceiver will not be damaged, but communication failures may occur.
- Fibre Coupled Power:
−
5 to 0dBm
- Input Power Range:
−
34 to
−
10dBm
- Optical Damage Input Level: 3dBm
