With respect to optical fiber cabling, a device that changes electrical signals to optical signals using a laser and associated electronic equipment such as modulators. Among various types of light transmitters are light-emitting diodes (LEDs), which are used in lower speed (100 to 256Mbps) applications such as FDDI, and laser diodes, which are used in higher speed applications (622Mbps to 10Gbps) such as ATM and SONET.

Trirated Cable is a high temperature, flame retardant electrical cable designed for use in panel building. Trirated Cable
Trirated Cable is so called because it meets the requirements of three different international standards: The British Standards Institute (BSi) BS 6231, UL (or Underwriters Laboratories), and CSA (Canadian Standards Association). Combining three international standards in one product, makes Trirated Cable suitable for use in equipment required to meet both North American and European wiring regulations.
This single core cable is described as ‘high temperature cable’ because of the high temperatures to which it is subjected
Voltage rating is another area over which the different standards vary. UL and CSA give Trirated Cable a voltage rating of
