Method of encapsulating optical fibres, comprises (a) bonding optical fibre to a first surface of a flat member having first and second opposite major surfaces; (b) placing the flat member in an air-tight chamber; (c) locating a sheet of plastic material, in the chamber such that it is adjacent the first surface of the member, the sheet having a first and second major surfaces, the first major surface of the sheet facing the first major surface of the member to be significantly lower than the air pressure on the second surface of the sheet, thereby to cause the sheet to press against the member; and (e) heating the plastics sheet sufficiently to cause it to adhere to the first surface of the flat member, thereby to encapsulate the optical fibres. |
