Optical Output Module
Each optical signal output I module provides 8 optical signals. Each
signal can be set to IRIG-B DC; Pulse A, B, C, D; TXD; IRIG-B

optical signal outputs.
Jumpers 20S1 to 20S8 control the outputs, as follows:
When 20S1 is as shown in (a) Optical output 1 is providing an IRIG-B DC optical signal
When 20S1 is as shown in (b) Optical output 1 is controlled by Pulse A
When 20S1 is as shown in (c) Optical output 1 is controlled by Pulse B
When 20S1 is as shown in (d) Optical output 1 is controlled by Pulse C
When 20S1 is as shown in (e) Optical output 1 is controlled by Pulse D
When 20S1 is as shown in (f) Optical output 1 is providing a TXD optical signal
The remaining positions DC’, A’ –
D’ and TXD’ (20S1 (g) –
(l)) are similar, except their on/off
states are opposite to the corresponding signals above.
Outputs 2
