Optical fiber that makes the connection between the Mosquito and the transducer. An adapter can also be used between the transducer and the delivery fiber.
the delivery fiber makes the optical connection between an optical transducer and the sensor [electro-photonics device]. Requires cutting a piece of optical fiber and connectorizing it.
Optical guide, can be of glass of polymer. Usually it comes in a cylindrical shape. Can be MM (multimode) or SM (single mode)
