Item Description
OPTO IN/OUT
SC-APC connection for the optical fiber.
DOI302 module with built in WDM has a single connector (combined RX/TX).
DOI301 module without WDM has two connectors, one for TX and one for RX.
UL OUT 1/2 Uplink ports (QMA) to the ICU.
DL IN 1/2 Downlink ports (QMA) to the ICU.
TP UL/DL Test ports (QMA) used to check the signal levels or noise in the system.
The two LEDs on the unit provide FOI status as shown in Table 11 .
