PM cables transmit a single-mode of light, from 350nm to 2,000nm, while maintaining the alignment of the polarization axis. PM cables are used in many applications including flow cytometry, downhole sensing, gyroscopes, and signal modulation. Coastal Connections typically stocks 20 different PM fibers to meet your needs.
SM cables transmit a single-mode of light, from ultraviolet (320nm) through infrared (2,000nm) including visible light (390-700nm). They were originally developed for long haul telecommunication systems however they are now used for Optical Coherence Tomography (OCT), LASIK eye surgery, military sensors, wind sensors, space communications, fiber to the home and many other applications. Coastal Connections typically stocks 30 different SM fibers to meet your needs.
MM cables transmit multiple modes of light, from ultraviolet (30nm) through Mid infrared (7,000nm) with core sizes ranging from 25um to 1mm. MM cables were originally developed for transmitting signals over shorter distances than SM fiber such as local area networks in buildings. Currently they are also used for power transmission, OCT, industrial sensors, laser surgery, and many other applications. Coastal Connections typically stocks 50 different MM fibers to meet your needs.
Coastal Connections is the world’s leading supplier of Fiber End-Caps for PM, SM and MM fibers in ferrules and connectors. Fiber End-Caps reduce the power density where laser light enters or exits the fiber resulting in longer life cables. Light with wavelengths shorter than 430nm can deposit contaminants onto the core of fibers. By adding a Fiber End-Cap, the power density is reduced eliminating the depositing of contaminants.
Laser Pigtails are designed for permanent coupling to a laser which makes their quality crucial. Typically, one side is a custom ferrule or capillary that is coupled to a free space laser beam while the other end has a fiber optic connector. On many pigtails, there is a feedthrough which secures the external cabling to the laser housing. Behind the feedthrough, 900um OD tubing is used for flexibility inside the chassis. Coastal Connections has standard feedthroughs for Laser Pigtails.
The Qualified FC connector is designed to meet the harsh environments of aerospace applications however it is affordable enough to be used wherever a rugged FC connector is needed. The QFC can mate to a standard FC connector and be used with almost any fiber type or cable construction.
Coastal Connections has been supporting space-based fiber optics since 2003. Prior to this Andy Devine, its president and founder, spent 2 years qualifying a fiber optic connector to survive 10 years of thermal cycling in space. Coastal Connections Qualified FC connector was tested to survive in space reducing your risks. Fiber end-caps further reduce your risk in free space communications.
Coastal Connections supports many major defense contractors and government research labs. Our expertise is sought after due to our ability to terminate unique optical fibers and their ability to survive in demanding environments. As an ITAR registered company, we control the import and export of defense related articles and information.
Vacuum feedthroughs allow optical fibers to pass through a vacuum chamber’s wall while maintaining a seal. Coastal Connections specializes in building custom feedthroughs with multiple fibers reducing your risk of a vacuum leak. Our proprietary fiber sealing technology does not add stress to the fiber allowing for sealing on bend sensitive fibers. Coastal Connections is the only company in the world that sells multichannel feedthroughs with polarization maintaining fibers.
As high power lasers come down in cost and the applications that require them goes up the use of high power cables is becoming much more common. The biggest risk in 1 to 60 Watt systems is burning of the fiber core due to power density at the end of the fiber. In higher power systems heat dissipation must also be considered. Properly built connectors can handle 150,000 Watts/mm2 of power in the core and 25,000 Watts/mm2 of power at the fiber end-face.
Fiber Bundles are used to transmit large spots of light, couple multiple fibers to a detector or for probes. Fiber bundles can have as few as two fibers, where one transmits light and the other collects it, or as many as 61 fibers. Fiber bundles typically use steel tubes to form probes or are inserted into SMA, FC, or E-2000 connectors. Coastal Connections can build the fiber bundle you need.
