  • Optical transceivers for path-protected passive optical metro access rings
    Publication number: 20050249499
    Abstract: For the special conditions of optical metro ring networks with entirely passive nodes, the invention proposes an optical splitting device in front of the optical transceivers, which has an asymmetrical splitting ratio. The excess attenuation caused by the beam splitting for the two paths can be adapted to the asymmetrical fiber link attenuation of the respective paths the device is connected to.
