Fiber End-Caps

Installing fiber End-Caps without impacting the optical quality of the main fiber and measuring the length of the final end-cap is very challenging. Coastal Connections has resolved these issues and builds 1,000s of end-cap assemblies every year for companies around the world.

High Power Mating Connector (PFC)

We believe Coastal Connections is the only company building high power mating cables with standard SMF-28E and SMF-Ultra, the most common single-mode fibers used. The technology is also compatible with other fibers.  Furthermore, Coastal Connections’ connector appears to be compatible with its strongest competitor.

Aligning PM Fibers to Each Other

Some LiDAR and interferometers require multiple PM fibers to be aligned to each other in a single ferrule or capillary. Other assemblies need the PM stress rods to be aligned to a flat or other feature. Coastal Connections has developed the tooling to align PM fibers very accurately and does it regularly.

Multi-Core Fiber Alignment

Coastal Connections developed the technology to align multi-core fibers very accurately in connectors and achieve low insertion losses.

Multi-Channel Vacuum Feedthroughs

Coastal Connections is possibly the only company in the world that can install many PM fibers in a single vacuum feedthrough. A vacuum feedthrough seals on a vacuum chamber allowing fibers to pass into the chamber without passing air at high vacuums.

PZ Fiber Termination

PZ Fibers polarize the light in the fiber as opposed to polarization-maintaining (PM) fibers that simply maintain the polarized light that goes into the fiber. These fibers have a lot of internal stresses that makes terminating them challenging.

Precision Length Cables

Many sensors require the optical path lengths to be controlled. Whether it is 100-meter-long cables where the individual channels need to be matched to within 1cm of each other or 0.3-meter cables where the fibers need to be within 1mm of each other. Coastal Connections also matches cables to +/-20ps of time delay.

Long Cable Feeding

Coastal Connections builds jacketed cables with custom fibers up to 100 meters long and does not know of any other company doing this without jacketing 1,000-meters of fiber which is impractical for very expensive fibers.

Testing PM PER Over Temperature

Testing PM PER Over Temperature
Coastal Connections measure Polarization Extinction Ratio (PER) over time and temperature automatically recording the values the entire time.

Measuring Beam Pointing Angles in Production

For free space optics and verifying ferrule quality knowing the angle of the fiber in the ferrule is very crucial, as the ID of fiber optic ferrules are not parallel to the OD.  Coastal Connections measures ferrules angles to 1/100th of a degree regularly in production.
