At 1550nm: Tight buffered fiber has a delay tempco of around 57 ppm/K Bare SMF28 has a delay tempco of about 7.9ppm/K Loose fibers in gel filled tube have a delay tempco of about 6.6ppm/K Bare Spectran fiber has a delay temcpco of about 5.1ppm/K Sumitomo phase stabilised fiber has a delay tempco of about 0.4ppm/K at 293K.
