Optical Transport Network

OTN (Optical Transport Network) Test Equipment is designed to validate, monitor, and troubleshoot high-speed optical networks carrying massive data traffic across carriers, cloud providers, and enterprise backbones. These tools are critical in ensuring that digital payloads—mapped using OTU1 to OTU4 and beyond—are transmitted with proper framing, synchronization, and error correction.

Located in Canoga Park, CA, TELECOM TEST TOOLS provides advanced, field-ready OTN Test Equipment to clients across North America. Our testers offer multi-rate support, protocol decoding, FEC monitoring, and service activation checks to ensure smooth operation across long-haul and metro optical layers. With intelligent interfaces, modular scalability, and cloud connectivity, TELECOM TEST TOOLS helps telecom operators, data centers, and transport vendors streamline deployments, perform efficient maintenance, and uphold strict SLAs across their DWDM and SDH/SONET-compatible infrastructure.

Case Studies

A national cloud backbone provider implemented TELECOM TEST TOOLS’s 100G OTN testers during a major DCI deployment. With built-in mapping verification and FEC tracking, they reduced activation time per node by 40% and detected previously unseen signal mismatches.

A telecom operator in the Northeast used TELECOM TEST TOOLS’s OTU4 testers for DWDM ring validation. Integrated loopback and G.709 alarms helped detect intermittent payload issues, leading to a 25% reduction in post-deployment fault tickets.

 In Ontario, a high-speed research backbone network integrated TELECOM TEST TOOLS’s OTN testers to validate 100G links across its cross-province fiber infrastructure. The testers’ real-time error analysis and FEC performance visualization ensured uninterrupted academic and scientific data flow.
