TeliSwitch
Technology
TeliSwitch introduces unique telecom architectures that address the key issues faced by operators in fiber optic network physical layers when they deploy optical networks, whether as backbone and backhaul networks, access networks, or in data centers.
TeliSwitch fiber cross-connect technology supports a unique feature set:
- Marginal optical impairments
- Non-blocking
- No-rearrange
- Latched connections
Marginal optical impairments and Latched connections attribute to physical fiber connections, where a robotic system plugs standard latching connectors into sockets. Accordingly, optical impairments stem entirely from selected connector performance and once plugged, connections remain unaffected by power failure or instability
Non-blocking and No-rearrange attribute to TeliSwitch patented architecture, implementing Polar rather that Cartesian design. Polar design exploits fiber ability to be slightly twisted without impairing the signal.
The patent
TeliSwitch technology is protected by several registered and pending patents.
The design is constructed around a spine, through which fibers reach plates (white elements in the image). These plates host one or more optical sockets each. Plates can be independently rotated, placing socket at desired angular coordinate.
Design bottom, not visible in the image, hosts vertically placed reels. Every reel holds fiber adequate to reach any plate. Reel structure, allowing pulling the fiber out and collecting it back into the reel, void of fiber damage or optical impairment, is TeliSwitch patented as well.
Thus, fiber extends to desired plate vertically, never crossing any other fiber.
Robotic subsystem establishes connection by rotating plate to desired angle, pulling fiber from the reel up to the target socket and plugging the connector into the socket. Accurate motion mechanics are assisted by visible image analysis. Robotic system removes connection by unplugging and graceful fiber retraction into the reel. Sockets not in use are protected from pollution by standard rubber plugs, as in a manual patch panel. Likewise, connectors not in use are protected from pollution parked at a dedicated parking plate.
Various device scales and connection topologies are achieved by these degrees of freedom:
The specialized robot performs the actual connection between the chosen self-retracting patch-cord loved inside a reel to the target switching connector mounted on a rotating plate. The robot is completely independent of the optical module, a feature that assures service continuity in case of loss of power or failure of the robot.
