A8KFDA

1218 MHz CATV or LAN Amplifier

 

/Overview/


This A8KFDA 1218MHz amplifier module has been designed for use in both CATV headend and broadband local area network (LAN) applications. The FDA module is based on ACI’s A8K Transmission platform may be used in any network with a bandwidth requirement of 45 to 1218 MHz. In two-cable networks, it is designed to operate in a one-way mode. Both gain and slope can be adjusted electronically through PCM controller on the A8K platform. The gain control is available for gain adjustment from 0 to 20 dB per 0.5 dB steps. The slope can be adjusted from 0 to 10 dB. Directional coupler test points are available on the rear panel to monitor the input and on the front panel to monitor the output RF levels. On the rear panel are RF input and output ports with F- type connectors.


/Features/

  • Bandwidth 45 to 1218 MHz

  • 32 dB gain at 1218 MHz

  • 0 ~ 20 dB gain control (controlled by microprocessor)

  • 0 ~ 10 dB slope adjustment (controlled by microprocessor)

  • 0 ~ 20 dB RF input level adjustment (controlled by microprocessor)

  • -20 dB DC input test point

  • -20 dB DC output test point

  • 19” Rack mount and 3 RU in height






A8KRFS

5 to 1218 MHz RF Switch

 

/Overview/


ACI’s A8KRFS is the headend equipment 5-1218 MHz RF Switch Module serves as the backup switching for HFC RF signal. The Switch module is a 3RU height unit, intended for use in the A8KMF3 chassis platform and up to 12 RF Switch modules can be integrated in the 19-inch high-density chassis A8KMF3RU. A8KRFS has two RF inputs. RFA is Primary Input by default and RFB is the Auxiliary (Aux) Input. RF switching will be automatically from Primary to Aux when the Primary input level falls below the desired setting threshold. A8KRFS module also has option for Manual A/B input selection switch. The A8KRFS has local and remote network management that provides real-time monitoring and controls via GUI, Webpage and PCM2L.


/Features/

  • BW: 5 ~ 1218 MHz

  • Two RF inputs and one RF output

  • Automatic backup switching from Primary to Auxiliary

  • Manual A/B input selection

  • Independent RF detector for each of the two RF inputs

  • Front panel status LED for A and B RF inputs

  • User defined Hi/Lo alarm limits and switching thresholds

  • Front panel -20dB RF output test point

  • Factory setting recovery via GUI, Webpage and PCM2L

  • Hot swap


/Applications/








A8KQDR

Quad Digital Return Receiver

 

/Overview/


ACI’s A8KQDR - Quad Digital Return Receiver is an integral part of the HFC system. It utilizes

state of the art digital return technology t hat allows deployment of compact and highly robust

high speed digital data for the broadband systems. The A8 K QDR is a 3RU module and up to 12

modules can reside in the 19 in high density chassis (A8KMF3). ACI's A8KQDR employs two hot pluggable Rx SFPs at the receiver frontend and four RF outputs at the backend that allows automatically bandwidth switchable in the field from 5 ~ 45 MHz to 5 ~ 85 MHz operation. Furthermore, the A8KQDR, with advanced design and path segmentation, has the ability to work with mixed bandwidths by accepting one 45 MHz Rx SFP and one 85 MHz Rx SFP. With the mixed BW Rx SFPs, the A8KQDR can provide two 45 MHz outputs and two 85 MHz outputs. Used in combination with the A34XMTDR Digital Return Transmitter in ACI s optical node, the

A8KQDR allows flexibility, quick and cost effective in terminating any available digital return node in the HFC network.


/Features/

  • 3RU module for 19“ rack housing

  • 45 MHz / 85 MHz bandwidth selectable with field exchangeable SFP return receiver sub module

  • Dual hot swap field upgradable SFP return receiver sub module

  • 4 Return RF outputs

  • RF output level control for each return path via HMS or SNMP

  • Maximum of 48 returns for Quad receiver modules per chassis

  • High RF output @36 dBmV / 6.4 MHz ch for 45 MHz or 85 MHz operation

  • Optical wavelength: 1260 to 1620 nm

  • Hot-swappable

  • 20 dB RF test point on front panel, selectable for each input

  • Remote control and monitor functions via HMS or SNMP
