Optische Sender-Empfänger für pfadgeschützte passive optische Metrozugriffringe

摘要

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.
