Photosensitive Single Mode Fiber

Thorlabs offers a range of photosensitive single mode fibers designed to provide high photosensitivity for UV radiation. These fibers offer low splice loss to transmission fiber and are suitable for a range of applications. Please see the table below for specifications regarding each product. We recommend T06S13 for use as a stripper tool when removing the buffer from these optical fibers in preparation for connectorization.

Response from Chris at Thorlabs: Thank you for your feedback. The effective index of the GF1 fiber is 1.469 at 1310 nm and 1.470 at 1550 nm.

Response from Jeremy at Thorlabs: We do not have data for the attenuation for the GF1. As an estimate, it would be on the order of tens of dB/km at 1550nm. The attenuation is relatively large because of the heavy doping but the typical length used is a few meters so the attenuation is not a big concern.

Could you give me the data of the attenuation @1550 nm ( dB/Km ) for this kind of photosensitive fiber ?
