Introduction
The Dali
t43™
is located close to the antenna, and hence helps reduce coaxial feedline RF losses, leading to
increased system efficiency, reduced cooling requirements and small physical size.
The
t43™
is connected to the
tHost™
via a fiber optic link, and can be installed 15km to 40km away from the
tHost™
.
The
t43™
contains two optical interfaces, supported by independent optical transceivers, enabling daisy-chain
connection of multiple
t43™
s to reduce total fiber deployment cost and enhance architecture flexibility.

The
t43™
Monitoring & Control function can be performed locally using an Ethernet interface, or remotely via the
t
Host™ when M&C signals are communicated over the fiber optic link.
The
t
43™ remote unit enclosure is sealed to the environment. Heat generated by the electronic components is
conducted to a rear heat sink and to the front lid. To increase efficiency of the heat sink, two external, long life,
environmentally sealed fans are provided on the top of the unit. Fans are controlled and monitored by remote unit
main processor. In a case of fan failure alarm will be generated and reported through the GUI.
