Optical Communication – Laser Source
Dual-Port Tunable Laser Source O- C- L- Band
Precision Light for Next-Gen Optical Communications & Testing with CoBrite DX2 Dual-Port Tunable Laser Source
In the world of optical communications, photonics research, and automated test systems, precision and flexibility in light sources are non-negotiable. The CoBrite DX2 Dual-Port Tunable Laser Source, developed by ID Photonics GmbH (Germany) and officially distributed in India by United Spectrum Instruments, is engineered to meet these demands. This advanced, rack-mountable laser solution offers one or two tunable laser ports, ultra-narrow linewidths, and intuitive remote-control capabilities via USB, Ethernet, or browser.
Understanding Dual-Port Tunable Laser Source O- C- L- Band
CoBrite DX2 is a dual-port, ultra-stable C/L-band tunable laser for DWDM, coherent telecom testing, and optical R&D. With high-resolution wavelength tuning across C, L, and extended bands, the DX2 is ideally suited for Dense Wavelength Division Multiplexing (DWDM) transport testing, coherent transmission, optical device validation, and general-purpose testing in lab environments. Its compact, space-saving 1 HE form factor allows seamless integration into telecom racks and optical benches.

FAQs
Can the two ports of the CoBrite DX2 be controlled independently?
Yes. Each port is fully independent in terms of wavelength tuning and power output, allowing for parallel testing or multi-channel configurations.
Does the DX2 support remote access without additional software?
Yes. The integrated web server enables access via any browser—on a PC, tablet, or smartphone—without installing dedicated control software.
How does DX2 differ from CoBrite DX1 and DX?
DX2 sits between DX1 and DX in capability. It offers more output ports than DX1 and a smaller form factor than DX, making it ideal for labs requiring multi-port flexibility without occupying too much rack space.
Is the DX2 suitable for coherent transmission testing?
Absolutely. Its ultra-narrow linewidth, polarisation-maintaining output, and stable power make it ideal for coherent modulation systems and local oscillator applications.
What automation environments are supported?
The DX2 supports SCPI-style commands via USB or Ethernet, and is compatible with LabVIEW, Python, MATLAB, and other standard test automation frameworks.
