Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Cisco® GainMaker® Broadband Amplifier platform includes a variety of RF amplifiers that address the divergent needs of today’s broadband networks. The Cisco GainMaker line extender provides customers with the ability to fine-tune and extend the network more cost effectively than by doing so with system amplifiers alone. The industry-leading gain and distortion performance of Cisco line extenders helps ensure world-class, end-of-line performance.

All Cisco GainMaker amplifiers provide superior two-way performance and reliability combined with a user-friendly layout. All share common plug-in accessories and perform to 1 GHz in the forward path. The line extenders in this family provide a single forward RF output port while the system amplifiers provide multiple forward RF output ports.

Cisco GainMaker line extender modules have increased gain and are mechanically compatible with previous Cisco GainMaker Line Extender II and III housing bases, often allowing upgrades to higher bandwidth with no respacing or resplicing. The DC power supply is modular and located in an updated housing lid for easy access. All Cisco GainMaker line extender modules are factory configured with reverse amplifier, diplex filters, forward interstage pads, and interstage equalizer to promote optimal performance. For output level control over temperature, optional configurations include either single-pilot Automatic Gain Control (AGC) or a thermal compensation circuit.

The Cisco GainMaker line extender has a single forward RF output port and is ideally suited for providing high (distribution) level RF in the feeder network

Data is based on stations configured for 2-way operation. AC currents specified are based on measurements made with typical CATV type ferroresonant AC power supply (quasi-square wave), and standard Cisco GainMaker Line Extender 12/24 V DC power supply, part number 593020.
DC supply has a user configurable 30, 40, or 50 VAC under voltage lockout circuit. Default setting is 30 V. 40 or 50 VAC under voltage lockout may be selected by changing the position of the lockout jumper.
Notes:
1.    Reference output tilt is specified as “Linear” tilt (as opposed to “cable” tilt).
2.    Forward Gain and Noise Figure measured with 0 dB input EQ and 1 dB input pad.
3.    Down tilt, the effect of cable is represented by a (-). Up tilt, the effect of equalization is represented by a (+).
4.    Loaded with 64 PAL B/G CW carriers from 112 to 600 MHz. “Digital” refers to 600 to 1002 MHz loading with QAM carriers at -6 dB relative to analog CW carrier levels.
5.    X-mod (at 15.75 kHz) specified using 100% synchronous modulation and frequency selective measurement device.
6.    Reverse Gain and Noise Figure for station with 0 dB reverse input pad, 0 dB reverse output EQ, and 1 dB output pad.
7.    Reverse Operational Gain, Noise Figure, and Return Loss are specified without the reverse switch option. If the reverse switch is installed, reduce gain by 0.5 dB, increase Noise Figure by 0.5 dB, and decrease Return Loss by 1 dB.
8.    Measured and specified as Composite Beat.
9.    Tested per CENELEC Standard EN50083-3 with reference output tilt. RF output level specified is at 1002 MHz (forward).
10.  Loaded with 64 PAL I CW carriers from 88 to 600 MHz. “Digital” refers to 600 to 1002 MHz loading with QAM carriers at -6 dB relative to analog CW carrier levels.
11.  Loaded with 73 NTSC CW carriers from 115 to 550 MHz. “Digital” refers to 550 to 1002 MHz loading with QAM carriers at -6 dB relative to analog video carrier levels.
12.  The gain at 102 MHz is less than 1.5 dB below the gain at 105 MHz. 102 to 105 MHz is recommended for out of band communication only. No video carriers should be used between 102 and 105 MHz.

Ordering Information

The Cisco GainMaker Line Extender is available in a wide variety of configurations. The desired configuration is “built” by accessing the Cisco Commerce Workspace tool at https://cisco-apps.cisco.com/cisco/psn/commerce. The user specifies the new Assemble To Order (ATO) Product ID for the Cisco GainMaker Line Extender “GM-LE” and the tool steps through the available options, from which to choose. Services may also be selected during this process. Once all the desired options are selected, the configuration and price are displayed. When the “Done” radio button is clicked, the configuration can be exported and saved for future use or immediate ordering.

This page contains ordering information for required and optional accessories. Please consult with your Account Representative, Customer Service Representative, or System Engineer to determine the best configuration for your particular application.
