A fibre interconnect is needed to connect one fibre to another. They can be useful for coupling patch cords to fibre-optic probes and other devices, or for any multiple-fibre application where coupling of standard optical fibres and accessories is preferable to creating costly and complex fibre-optic assemblies.
Bulkheads
Avantes bulkhead adaptors for TO-5 and TO-18 packages are ideal for coupling an LED to a fibre-optic cable: the back side has space for an LED.
