Cisco Cisco Compact EGC Dual Output Amplifier A93270 数据表
Description
The 862 MHz Compact Amplifier Platform includes a variety of
RF amplifiers that address the divergent needs of today’s
broadband networks. All Compact amplifiers are optimized for
both trunk and distribution applications and provide superior 2-
way performance and reliability combined with a user-friendly
layout. All share common plug-in accessories.
Compact amplifiers can be configured with diplex filters,
forward interstage pads and interstage equalizer, to ensure
optimal performance. The reverse amplifier is an integral part
of all Compact amplifiers and enables a reverse bandwidth of
more than 65 MHz. The amplifiers within this series utilize the
orange plug-in 3-pin attenuator pads. These pads provide
maximum user friendliness and make it very easy to replace the amplifier, in case of failure. Since the pads are
simply moved to the new amplifier, there is no need for manual and complex adjustment procedures. And since
the amplifiers within this series use the same pads for both attenuation and input tilt, operators will be able to
lower their cost of spares. The extra AUX plug-in socket means that it is possible to insert cable correctors,
inverse equalizers and attenuation pads at the input. The plug-in splitters at both input and output make it
possible to configure the amplifier to the network and as such eliminate the need for expensive external power
passing passives.
The Compact Amplifier 93212 features a high output level to help cable operators deliver greater reach with
fewer actives. The unit features improved flatness and re-arranged test point reference for more straight
forward reverse path alignment and common reference for signal injection point and test point. Both test point
and signal injection point utilize directional couplers to ensure a precise reverse alignment that is virtually
independent of impedance mismatches in the network.

All Compact amplifiers can be configured with a Scientific-Atlanta status monitoring transponder (SMC or HMS)
to enable remote monitoring of critical amplifier parameters and remote control of the built-in 3-state reverse
switch. By switching to detection mode (-6 dB) it can be observed from which part of the network the ingress
derives. Once a failure has been located, the defective network segment may be isolated until the failure has
been eliminated and the remaining part of the reverse path is ensured normal traffic.
