A concept for balancing a load in a mobile communication network, comprising receivingreceive data from a radio transceiver using a first interface and determininga first receive data packet and a second receive data packet from the receive data, the first receive data packet and the second receive data packet being associated to different services. The concept comprises forwardingthe first receive data packet to a first processing unit using a second interface, and forwarding the second receive data packet to a second processing unit using the second interface.

Concept for load balancing in a radio access network

An optical duplexer, configured as a directional coupler, is integrated into an optical coupling arrangement with a fiber optic pigtail, constructed in planar-optical hybrid technology on a substrate (1). To reduce the required surface area and decrease optical cross talk, the branch of the directional coupler (waveguide 6, branch 7) is sharply bent. The bend is equipped with a reflecting mirror (11) integrated opposite the inner edge (10) of the bend. Furthermore, the waveguiding end of the bent branch (7) is equipped with a cylindrical lens. A laser diode (8) is located before this, and a photodiode (5) is located before the angled end of the straight-line integrated waveguide (2).

Optical coupling arrangement

An optical switch has a substrate and a transparent material in which a three-dimensional diffraction pattern is recorded which is capable of diffracting light, the material having non-linear optical properties and extending in the form of a first layer above the substrate. At least one first electrode and at least one second electrode are provided for varying the diffraction pattern in accordance with applied voltages.
