Abstract
An optical fiber distribution network includes non-destructive read taps disposed in series which create extremely small attenuations of an optical signal being tapped, and which increase the bandwidth of an optical fiber being tapped. The network further includes non-destructive write taps disposed in another series which each inject an optical signal into a second optical fiber while inducing minimal attenuation of a pre-existing optical signal in the second fiber.
