Methods and systems for bias control in an optical switch fabric include monitoring optical power at outputs of a plurality of switch elements in an NN switch fabric that has N inputs, N outputs, and M2 stages, each switch element having a respective unique radio frequency tone. A bias control of each of the plurality of switch elements is adjusted. It is determined whether the optical power at the outputs of each respective switch element after bias control adjustment conform more closely to a predetermined criterion relative to the monitored optical power at the outputs of the respective switch element prior to adjustment.

Data center interconnections, which encompass WSCs as well as traditional data centers, have become both a bottleneck and a cost/power issue for cloud computing providers, cloud service providers and the users of the cloud generally. Fiber optic technologies already play critical roles in data center operations and will increasingly in the future. The goal is to move data as fast as possible with the lowest latency with the lowest cost and the smallest space consumption on the server blade and throughout the network. Accordingly, it would be beneficial for new fiber optic interconnection architectures to address the traditional hierarchal time-division multiplexed (TDM) routing and interconnection and provide reduced latency, increased flexibility, lower cost, lower power consumption, and provide interconnections exploiting NMD Gbps photonic interconnects wherein N channels are provided each carrying M wavelength division signals at D Gbps.

Devices, computer-readable media and methods are disclosed for determining reachability for a wavelength connection in a telecommunication network. For example, a processor deployed in a telecommunication network may calculate a fiber loss on a link in the telecommunication network using optical power measurements and determine that a destination node of a wavelength connection is not reachable via a path that includes the link based upon the fiber loss of the link that is calculated. In one example, the determining is based upon a number of links in the path, an effective fiber loss for each link in the path, a penalty for nodes in the path, and an acceptable loss value. The processor may further perform a remedial action in response to determining that the destination node of the wavelength connection is not reachable via the path.

Apparatus and methods automatically track the physical connection configuration of fiber optic cables using high spatial resolution RFID tag readout and high-resolution optical scanning In further embodiments, the acquisition of s RFID and/or optical scans are performed by a robotic scanning system.

Implementations described and claimed herein provide systems and methods for a configurable optical peering fabric to dynamically create a connection between participant sites without any physical site limitations or necessity of specialized client and network provider equipment being located within such a facility. Client sites to a network may connect to a configurable switching element to be interconnected to other client sites in response to a request to connect the first client site with a second site, also connected to network, via the switching element. A request may trigger verification of the requested and, upon validation, transmission of an instruction to the switching element to enable the cross connect within the switching element. The first site and the second site may thus be interconnected via the switching element in response to the request, without the need to co-locate equipment or to manually install a jumper between client equipment.

Aspects of the present disclosure describe systems, methods. and structures directed to an integrated 3-way branching unit switch module suitable for undersea application.
