Broadband Passive Optical Network
BPSK

Binary Phase Shift Keying; A digital modulation technique in which the carrier phase can have one of two possible values, namely 0 degrees or 180 degrees. [Sat07]
Bragg Grating

A technique for building optical filtering functions directly into a piece of optical fiber based on interferometric techniques. Usually this is accomplished by making the fiber photosensitive and exposing the fiber to deep UV light through a grating. This forms regions of higher and lower refractive indices in the fiber core. [Fib111]
