scope:

This standard establishes physical characteristics and technical criteria for Synchronous Optical NETwork (SONET) interfaces at standard rates associated with the Network Interface (NI), for electrical interface applications. Covered herein are SONET Physical Media Dependent (PMD) specifications (such as electrical parameters and connectors). Other necessary criteria for compliance with the proper interfacing of the connecting customer installation equipment are found in the base document of this series. This standard addresses network and customer installation compatibility and is not to be construed as a constraint on the internal operations of the network or the customer installation equipment. Other documents included in the ANSI T1.416 series, at the time this document was approved, are listed below

ANSI T1.416-1999, Telecommunications - Network to Customer Installation Interfaces - Synchronous Optical NETwork (SONET) Physical Layer Specification: Common Criteria

ANSI T1.416.01-1999, Telecommunications - Network to Customer Installation Interfaces - Synchronous Optical NETwork (SONET) Physical Media Dependent Specification: Multi-Mode Fiber

ANSI T1.416.02-1999, Telecommunications - Network to Customer Installation Interfaces - Synchronous Optical NETwork (SONET) Physical Media Dependent Specification: Single-Mode Fiber

The provisions of this standard are intended to be consistent with applicable requirements concerning safety and environmental conditions.
