Claim Text:
1. A method of transmitting source light to supply light to a plurality of Sagnac interferometers comprising: coupling said source light into a first directional coupler to split said source light into a second light beam and a third light beam and supplying light from said second light beam to a first Sagnac interferometer and supplying light from said third light beam to a second directional coupler; further coupling said first directional coupler to deliver light returning from said first Sagnac interferometer to a first detector and operating said first detector to provide a signal indicative of rotation of said first Sagnac interferometer; and coupling said third light beam into said second directional coupler that splits said third light beam into a fourth light beam and a fifth light beam, supplying light from said fourth light beam to a second Sagnac interferometer and further coupling said second directional coupler to deliver light returning from said second Sagnac interferometer to a second detector, and operating said second detector to provide a signal indicative of rotation of said second Sagnac interferometer.
