CoBrite DX is a high-performance, multi-port tunable laser for DWDM, coherent transmission, and photonics R&D.

Whether used in DWDM transport testing, coherent transmission, local oscillator roles, or research environments, the CoBrite DX offers unmatched flexibility with 1, 2, or 4 laser ports. Supporting C-band, L-band, and extended bands, this compact, rack-mountable system enables researchers, engineers, and telecom professionals to precisely generate, tune, and manage laser wavelengths in the most demanding applications.

Engineered for High-Throughput Optical Testing

• Flexible Multi-Port Design – Available with 1, 2, or 4 independent laser ports, each configurable for C, L, C+L, or extended X-band coverage, reducing the need for multiple standalone units.
• Ultra-Narrow Linewidth – <25 kHz linewidth ensures superior coherence and low phase noise for coherent detection, advanced modulation (QPSK, QAM), and interferometric precision.
• Broad Wavelength Tuning – Supports C-band, L-band, C+L-band, and X-band for dense DWDM testing and multi-band photonics research.
• Remote Control Ready – USB + Ethernet with SCPI-style commands and built-in browser interface—no software installation required, enabling decentralised test and automation.
• Touchscreen Local Interface – Large front-panel colour display for intuitive control, manual wavelength selection, and real-time monitoring in shared lab environments.
• Compact Rackmount Design – 2HE half-width, 19” rack housing maximises lab and telecom rack efficiency while delivering multi-port scalability.

Why It Delivers More

DWDM Transport Testing in Telecom Networks

As Dense Wavelength Division Multiplexing (DWDM) systems evolve, they require rigorous testing across many wavelength channels. The CoBrite DX delivers:

• High-resolution wavelength tuning
• Multiple lasers in one unit for simultaneous testing
• Stable, low-noise outputs for repeatable measurements

Coherent Optical Transmission

The narrow linewidth and polarisation-maintaining outputs of the CoBrite DX make it ideal for coherent optical transmission systems, where signal fidelity and phase noise directly affect data rates.

Supports:

• QPSK, 16-QAM, and 64-QAM systems
• Local oscillator generation
• Lab testing of coherent transceivers and modulators

R&D and Academic Research

For universities and research institutions working in photonics, quantum optics, or spectroscopy, the CoBrite DX acts as:

• A tunable local oscillator
• A transmitter source for modulation experiments
• A narrow-band probe in interferometric studies

Local Oscillator in Optical Coherent Detection

Stable and tunable laser output is vital in coherent receivers, and the CoBrite DX meets this demand with high output stability, precise tuning, and narrow linewidth. It ensures optimal performance as a local oscillator across L, C, and C+L bands.

General Optical Testing & Component Characterisation

Engineers and technicians can use the CoBrite DX to characterise:

• Optical filters and AWGs
• Photodetectors and modulators
• WDM systems and passive components
