ANSI SCTE 161-2016 pdf free download.Drop Amplifiers
1. Scope
The purpose of this specification is to recommend mechanical and electrical standards for broadband radio frequency (RF) devices whose primary purpose is to amplify signals presented to an input port and deliver the amplified signals to one or more output ports. The devices are also required to pass signals in a different range of frequencies in the return direction and, optionally, may provide amplification of such return signals. The specification’s scope is limited to 75 ohm devices whose ports are provided with F connectors. The most common use for such devices is on-premises RF signal distribution. Devices covered by this specification include products commonly known as Drop Amplifiers. They may be mounted within Network Interface Device (NID) housings on dwellings or independently within dwellings. They are not intended to be cascaded with other Drop Amplifiers. Two levels of compliance are specified. Devices meeting all electrical, mechanical and environmental specifications may be specified as meeting the requirements of this specification without qualification. Those meeting electrical and mechanical, but not the environmental requirements specified in Section 6 may be designated as meeting this specification with the suffix “For indoor use only” and the products must be marked as specified herein to guide users in their appropriate application. The specification is not intended to apply to specialty devices, nor is it intended to limit or restrict any manufacturer’s innovation and improvement.

3. Mechanical
3.1. RF Ports
1. All RF ports shall be type F. F-female ports shall conform to the requirements of ANSI/SCTE 01 2015 (for outdoor use) or ANSI/SCTE 02 2015 (indoor use). F-male ports shall conform to the
requirements of ANSI/SCTE 124 2011.
2. Where more than one connector exits from a common surface of the device, connectors will be
spaced a minimum of 0.925” (23.49 mm) apart, center-to-center. Refer to Figure 1.
3.2. Power Port
The power port, if provided, may be a type ‘F’ female connector, a permanently attached cord, or some other connector of the manufacturer’s choice. The device must meet all requirements of this specification in all powering configurations.
3.3. Mounting
Mounting holes or slots may be located at the manufacturers’ preferred locations provided they meet the requirements of 3.3.1 and 4.3.2 herein. Mounting holes or slots may be located at the manufacturers’ preferred locations provided they meet the requirements of this section below:
1. Mounting holes or slots shall be of such size and location as to allow orthogonal mounting of the
device on a hole pattern grid of 0.500” by 0.500” (12.7mm x 12.7mm), capable of employing
standard #6 (M3.5) hardware (Figure 1).
2. Mounting holes, slots, or bonding points shall be located as to not interfere with open-end wrench
access to the F ports.
