Collaborative Innovation for Terabit-Class Networks
The Multi-Terabit Test Solution is a fully validated, high-performance optical test and measurement platform developed in close collaboration with the Fraunhofer Institute for Telecommunications — one of Europe’s leading applied photonics research organisations. It reflects deep system-level expertise in coherent optical communications combined with an industry-leading portfolio of coherent optical test instruments across laser sources, transmitters, receivers, and spectrum analysis.
Designed to address the specific characterisation challenges of next-generation multi-terabit optical communication systems — including 400G, 800G, 1.6T, and beyond — this solution enables accurate measurement, end-to-end validation, and performance optimisation of ultra-high-capacity transmission technologies under realistic operating conditions. Unlike collections of individually sourced instruments that require integration, calibration, and validation by the customer, the Multi-Terabit Test Solution is delivered as a pre-integrated, co-validated system where every building block has been confirmed to work correctly together before delivery.
Key performance fact: The Multi-Terabit Test Solution supports data rates of up to 1.4 Tb/s per individual optical carrier and up to 200 simultaneous DWDM channels — making it the highest-capacity coherent optical test platform available in India today for research, component qualification, and system integration validation.
Flexible and Scalable Multi-Vendor Test Architecture
By combining proprietary ID Photonics instruments with carefully selected partner technologies, the Multi-Terabit Test Solution delivers exceptional flexibility and scalability that no single-vendor platform can match. The core building blocks — CoBrite tunable laser sources (CoBrite DX, DX2, and MX series), OMFT dual-polarisation optical multi-format transmitters, and CORX coherent optical receivers — are seamlessly integrated with partner technology from the Fraunhofer Institute for Telecommunications and industry measurement leaders including Keysight Technologies.
This multi-vendor, modular architecture enables the solution to be precisely tailored to a wide range of test requirements:
- Single-carrier coherent validation — characterise individual 400G, 800G, or 1.6T coherent transceivers with a complete transmitter + receiver test chain
- Multi-channel DWDM system testing — emulate and evaluate realistic dense DWDM networks with up to 200 simultaneously active channels
- Advanced modulation format research — test DP-QPSK, DP-16QAM, DP-64QAM, probabilistically shaped QAM, and beyond with the same platform
- Component-level optical characterisation — use the platform as a flexible signal source and reference receiver for optical amplifiers, filters, PICs, and transponders
System-Level Design with Full Validation and Integration
What fundamentally differentiates the Multi-Terabit Test Solution from a collection of individually purchased instruments is its system-level design approach — the philosophy that the test platform is an integrated system, not an assembly of parts.
Every building block is carefully selected based on its performance in the specific role it plays within the overall test architecture. Every interface between components — optical connectors, RF cables, control interfaces, timing synchronisation, automation protocols — is engineered and validated as part of the complete system. Every measurement result the platform produces has been confirmed against known-good references before delivery.
This system-level validation approach delivers three specific advantages that directly reduce customer risk:
- Reduced integration time — customers receive a working test system, not a collection of instruments that need weeks of integration effort before producing valid measurements
- Guaranteed measurement consistency — because the system has been validated end-to-end, measurement results are reproducible across sessions, operators, and sites without individual instrument recalibration
- Application-specific optimisation — the system is configured specifically for the customer’s test scenarios (modulation format, channel count, baud rate, optical amplification chain) rather than delivered as a generic platform that must be reconfigured for each application
The result is a turn-key multi-terabit testing solution that is precisely tailored to each customer’s application, reducing setup complexity and guaranteeing results that meet the most demanding optical network testing and R&D requirements from day one of deployment.
