A robust, reliable, and flexible transport over the OXC. On the core side, the interface is paired with a front-end interface (e.g. PCIe PHY).
On the optical side, the interface implements high-speed SerDes to interface with external optical pluggable modules (e.g. SFP/QSFP etc.).
The main function of the interface is to retime the front-end in the optical clock domain and vice versa. The interface can be paired with various front-end configurations with dynamic gearboxes to accommodate the varying datum speed and width requirements (on the receive side) and to faithfully reproduce (on the transmit side) varying sized front-end datum.
The interface is further customized to allow configuration with a varying number of SerDes (i.e. channels) to form bundles that implement a singleton-independent interface towards exactly one other FIC.
The interface implements Reed Solomon (RS) to provide forward error correcting capability and allows for de-skew and realignment of datum on the receiving side.
The interface also implements a register map to allow configure-ability via the local MSP (Linux). Additionally, the interface also provides an in-band control channel for one FIC to communicate with paired FIC over the optical interface.

OXC L1 Layer is a cluster of NxM cross connect switches, with each N input ports and M output ports arranged in scale-out topology to connect with different resources that are managed as part of this domain. Each port on the switch consists of an In (Rx) and Out (Tx) ports that can be interleaved (1-in, 1-out, 2-in, 2-out) or sequential (
OXC L1 Layer is a cluster of NxM cross connect switches, with each N input ports and M output ports arranged in scale-out topology to connect with different resources that are managed as part of this domain. Each port on the switch consists of an In (Rx) and Out (Tx) ports that can be interleaved (1-in, 1-out, 2-in, 2-out) or sequential (1, 2, ...N and N+1, N+2 ... N+M).
Benefits:
- Any port operates at any data Rate
- No upgrade needed when migrating from 10G to 100G/200G/400G or more
- No transceivers needed
- No OEO (Optical-Electrical-Optical) conversion i.e. lowest possible latency
Open-APIs - Each OXC provides standard SSH/HTTP/TL1/REST interfaces to manage the devices and build-up of cross-connects in the context of individual configurations.
Each OXC element maintains the up-to-date connectivity information in its database and remains persistent across reboots.
Each OXC element monitors the health of individual x-connections and reports out any alarms or unexpected system events.
