Our high-power connectors incorporate several advantageous features. We use copper ferrules with a bored front to dissipate heat better and free-standing fiber tips to minimize the probability of damage to uncoupled light. The front part of the connector is epoxy-free to prevent burning. It has a key pin so that each connector can be pre-aligned to achieve and ensure uniform low loss. AR coating is an option to further reduce the loss and increase reliability. Moreover, we offer mode-stripping which removes most of the light from fiber cladding. We further offer fiber end-cap enhancement of these connectors for higher power handling, which expands the Mode Field Diameter and thus reduces the power density at the glass-air interface to a level below the damage threshold.
