<p>An optical fiber (10) for use in making components of an optical communication system has cladding (14) and core (12) materials the constituents of which cause a component made from the fiber to have a rate of change with respect to temperature of a response to a signal which passes through zero at a temperature Tm which is at or near a selected temperature, or falls within a selected temperature range; and the value of Tm of a fiber can be controllably changed by changing the concentration of B2O3 in the fiber core material.</p> |
