1-2 Flex Max901e 1GHz Trunk and Bridger Amplifiers 1502154 Rev D
Overview
Flex Max901e 1 GHz Trunk and Bridger Amplifiers are the new industry standard for RF distribution
products. The FM901e continues to offer the same excellent features, reliability, and performance
customers have come to rely on with C-COR’s legacy 700/800/900/901 series amplifiers. In
addition, operational bandwidth is extended to 1 GHz, plug-in diplex filters provide the capability for
higher return bandwidth options [Next Generation Network Architecture
1
(NGNA) compatible] as
well as international applications, and, an option for element management monitoring is offered.
The Flex Max901e offers 1GHz technology that lets broadband service providers increase forward
capacity for HDTV, HSD, and VOD—allowing over 60 additional HDTV channels in a lineup. Operating
specifications, such as gain and tilt, are maintained at 550 MHz, 750 MHz, and 870 MHz with
extended gain and tilt out to 1 GHz. These design considerations enable reuse of legacy amplifier
housings and existing spacing—eliminating the cost of resplicing.
Flex Max901e amplifiers feature automatic level control pilot frequencies common to legacy FlexNet
amplifiers. The
ALC PAD
location reduces the ALC pilot frequency operating level range by 6 dB for
a QAM signal in case digital channels will be loaded in the bandwidth, below 550 MHz, that is
traditionally reserved for analog channels. Flex Max901e trunk amplifiers (FMTEs) provide a single,
trunk level output and up to four bridger outputs, depending on the specific amplifier model.
Flex Max901e bridger amplifiers (FMBEs) provide only bridger outputs.
Additional features of the Flex Max901e series are:
■
While all trunk amplifiers are factory aligned for 1 GHz operation, they can be ordered
preconfigured for 750/870 MHz operation as spares or extensions
■
Ability to:
– drop trunk modules into existing 700/800/900 series locations as a spare without the
need to rebalance amplifiers downstream
– accept all legacy 750 and 870 MHz forward EQ plug-in accessories—new plug-in
guides ease installation
■
–20 or –25 dB internal and external testpoints match existing system design
■
Expanded ALC pilot selection to match existing system builds
For specific amplifier characteristics, refer to the C-COR customer specification sheet for the
particular amplifier in question. Flex Max901e model options are detailed in
Part Numbers (Model
Options) on page 1-4. Depending on the configuration, some options may not be available.
A comprehensive overview and various comparisons (features, specifications, etc.) can be
found in Appendix A.
Please consult your C-COR Customer Service Representative for further information.
1. Next Generation Network Architecture (NGNA) is a set of specifications developed by a cable industry think tank
to guide the development and deployment of future products, services, and applications. The basic premise is
to route IP and MPEG traffic over a single Gigabit Ethernet backbone to the cable network edge.
Note While the Flex Max901e trunk amplifiers are designed and factory aligned for
1 GHz operation, they can also be configured for use as spares in existing 750 or
870 MHz systems. Refer to Factory-Shipped Configurations for Flex Max901e Trunk and
Bridger Amplifiers beginning on page 5-9 for the plug-in accessories and their locations
for 1 GHz or 750/870 operation.
Note Flex Max901e trunk amplifiers (1 GHz operation) can be configured with equal
or unequal tilt on the trunk and bridger ports. Flex Max901e amplifiers configured for
750/870 MHz operation offer trunk and bridger ports with equal tilt. Refer to
Factory-Shipped Configurations for Flex Max901e Trunk and Bridger Amplifiers on page
5-9 for more information.
