3.1.1 Optical Fiber Uplink/Downlink Ports
The optical fiber uplink/downlink ports transmit and receive optical signals between
the Main Hub and up to four Expansion Hub(s) using industry-standard SMF or
MMF cable. There are four fiber ports on the front panel of the Main Hub; one port
per Expansion Hub. Each fiber port has two female SC/APC connectors:
• Optical Fiber Uplink Connector
This connector (labeled
UPLINK) is used to receive the uplink optical signals from
an Expansion Hub.
• Optical Fiber Downlink Connector
This connector (labeled
DOWNLINK) is used to transmit the downlink optical sig-
nals to an Expansion Hub.
CAUTION: To avoid damaging the Main Hub’s fiber connector
ports, use only SC/APC fiber cable connectors.
3.1.2 Communications RS-232 Serial Connector
Remote Monitoring
Use a standard serial cable to connect a modem to the 9-pin D-sub male serial con-
nector for remote monitoring or configuring. The cable typically has a DB-9 female
and a DB-25 male connector. The following figure shows the cable pinout.
