2.3.2.7 Remote Fiber Connector Cable Assembly
A fiber connector cable assembly is provided with 10 meters of environmentally
hardened cable and 1 meter of exposed, un-terminated single-mode 900μm optical
fiber sufficient for splicing in an OSP splice tray.
2.3.2.8 Remote Antenna Cable Connections
The TX0/RX0 antenna cable connections are through 50-ohm N-type female
connectors. The Remote includes an internal Duplexer which allows a single antenna
cable to carry both forward and reverse path RF signals between the antenna and the
Remote. The RX1 diversity antenna cable connections are through 50-ohm N-type
female connectors.
2.3.2.9 Remote Grounding
A double-ground stud and ring lug is supplied with the unit. A #6 copper wire
terminated with the provided ring terminal must be provided to link the Remote to
an earth ground source.
2.3.2.10 Remote Cooling
The electronic compartment of the Prism is sealed to the environment. Prism
conducts its heat to a rear heat sink and the front doors. Two external
environmentally hardened fans are controlled and monitored by the system. When
turned on, these fans pull air over the external surfaces of the enclosure to ensure
the electronics run within their rated temperature. The fans run at three different
speeds depending on the internal temperature of the system. An alarm is generated
if a high temperature condition occurs within the enclosure.
The maximum ambient operating temp is 50°C (122°F).
The pigtail is a reduced bending radius type fiber. Therefore not all fusion splicers will
work to sp
lice it. Do not use a splicer that uses light to align the cores.
30M, 40M, 60M, 80M, 100M and 150M fiber connector cable assemblies are also
available from ADC.
For proper and safe equipment operation, an approved earth ground connection must
be provided. The re
commended minimum wire size is #6 AWG copper wire.
