SDH & DWDM Systems
Survey, Planning, Installation, and Commissioning Services
In optical transmission infrastructures, high capacity, low latency, and uninterrupted service are only achievable through proper engineering processes.
Our expert team manages every stage of survey, planning, installation, testing, commissioning, acceptance, and service migration for SDH (Synchronous Digital Hierarchy) and DWDM (Dense Wavelength Division Multiplexing) systems.
Site Survey and Field Analysis
- Detailed examination of the existing infrastructure, fiber routes, and field conditions
- Performing and reporting OTDR and PMD/CD tests
- Evaluating the suitability of power, cooling, and system room infrastructure
- Preparing the layout plan and survey report with complete documentation
Planning and Engineering
- Conducting fiber optic route mapping and distance analysis
- Preparing wavelength plans based on active equipment capacity, channel spacing, and transceiver types
- Designing optical patch panel layouts, cable routing, and inter-site connection diagrams
- Developing traffic routing, protection, and redundancy topologies
Installation and Cabling
- Installing active systems and performing internal/external cabling
- Mounting cable management systems
- Performing power cabling, grounding, and mechanical quality checks
- Post-installation inspection and documentation
Testing and Commissioning
- Conducting BER tests
- Performing power balance, OSNR, and channel validation measurements
- Traffic testing, circuit activation, and test reporting
Service Migration and Acceptance
- Planning seamless service migration on live circuits
- Verifying redundancy and protection of active paths
- Performing customer acceptance tests and final project approval
- Delivering final documentation and as-built reports
Maintenance and Technical Support
