1.1. Scope
The purpose of this document is to recommend mechanical, environmental and electrical standards for broadband radio frequency (RF) devices whose primary purpose is to divide signals presented to an input port among two or more output ports with a fixed division ratio that is nominally independent of frequency within the specified bandwidth limits of the device. Alternately, such devices can be used to combine signals from several input ports into a common output port. Its scope is limited to 75-ohm devices whose ports are provided with type F connectors. The most common use for such devices is on- premises RF signal distribution. Products covered by this specification include signal splitters (2, 3, 4, and 8-way), directional couplers, combined splitter/directional couplers and power inserters. Devices meeting all electrical, mechanical and environmental specifications are specified as meeting the requirements of this specification. Those meeting electrical and mechanical, but not environmental requirements are designated as “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.
1.2. Areas for Further
Investigation or to be Added in Future Versions This document provides specifications or procedures for frequencies up to 1002 MHz. DOCSIS 3.1 specifications include operation at frequencies up to 1218 MHz, and optionally, to 1794 MHz. Specifications or procedures for those higher frequencies should be considered in a future revision of this document.

3.1. RF Ports
1. RF ports on devices intended for indoor applications must conform to the requirements of ANSI/SCTE 02 2015.
2. RF ports on devices intended to be rated for outdoor use must conform to the requirements of ANSI/SCTE 01 2015.
3. Where more than one connector exits from a common surface of the device, connectors will be spaced a minimum of 0.925″ apart, center-to-center.
3.2. Mounting
Mounting holes or slots may be located at the manufacturers preferred locations provided that they meet the requirements of 2.2.1 and 2.2.2 herein.
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″ (12.7 mm x 12.7 mm), 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.
