Laser Diodes & Sources
Fiber Coupled VCSEL Laser Diode 850nm
The FCVC is a fiber-coupled, vertically-emitting, single-mode diode laser based on a semiconductor quantum-well configuration. The diode chip is housed in a TOCAN package, featuring TEC cooling and a power monitoring photodetector. Wavelength tuning can be achieved through laser current and temperature adjustments. Our 850nm single mode VCSEL is designed for high-speed, high-performance communication applications. All of our laser products are Telcordia GR-468 qualified and comply with RoHS Directives.

System integration
Integration and compatibility
Use these checks to connect Fiber Coupled VCSEL Laser Diode 850nm to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SM780, PM780, 50/125 · Fiber Buffer: 900μm tube
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 850nm
- Check the Laser Diodes & Sources passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
- Control interface
- Driver: Non, PCB, Benchtop
- Match supply voltage, analog or digital command range, connector pinout and default optical state to the instrument interlock. Confirm the unpowered state explicitly — it decides what happens to the link on a power failure.
