Transmitter laser products are designed for applications where controlled optical pulses or modulated laser output must be delivered into optical fiber systems. Modulight’s portfolio includes Fabry-Pérot and DFB laser sources in several telecommunications wavelength regions.
The current portfolio includes pulsed laser sources specifically designed for Optical Time-Domain Reflectometry (OTDR), with products available in wavelengths such as 1310, 1490, 1550, and 1625 nm. Packaging options include coaxial fiber-pigtail, TO-can, and butterfly configurations.
These laser sources provide compact, application-ready building blocks for fiber characterization, optical testing, and other systems requiring controlled laser transmission into optical fibers.
