The Agilent/Keysight N1675A is an optical test module for SONET/SDH network validation, commissioning, and maintenance. Designed for the N1610B Service Advisor Portable Test Tablet, it delivers OC-3/OC-12 and STM-1/STM-4 testing capability with support for both concatenated and channelized line interfaces. The module integrates into a modular test platform, enabling field technicians to perform comprehensive protocol and layer 1 diagnostics on synchronous optical networks.
Technical Specifications
• Optical Interfaces: 622/155 Mbps with single-mode 1310 nm Intermediate Reach (IR) optics

• SDH Support: STM-4 (AU4-4c) and STM-1 (AU-3) line rates
• Line Configuration: Concatenated or channelized operation
• Form Factor: Single-width modular test module
• Host Platform: Agilent N1610B Service Advisor Portable Test Tablet (supports 2 single-width or 1 dual-width module)
– Key Features
• Single-mode 1310 nm optical transceiver for intermediate reach applications
• Modular architecture for multi-module test configurations
• Support for both SONET and SDH standards in a single module
• Flexible line rate and formatting options to match diverse network topologies
– Typical Applications
• SONET/SDH network commissioning and acceptance testing
• Optical path performance monitoring and troubleshooting

– Compatibility & Integration
The N1675A integrates directly into the Agilent N1610B Service Advisor platform, which accommodates multiple test modules simultaneously. This modular design enables users to extend test coverage across different network interfaces by combining compatible modules within a single portable test tablet. The module represents a discontinued product line; however, technical documentation remains available for legacy system support and reference.
