Software-controlled optical circuit switching
Rapid provisioning, protecting, testing and monitoring of connections. Eliminates human error from manual patching. Enables remote operations. Reduces manpower costs.
Maximised performance and uptime
Minimal impact on network optical power budgets. Maximised reliability, uptime, and switch availability. Minimal power consumption (compared to OEO switch).
Secure transmission
Light passes through switch unaltered. Data not interrogated for routing. Integration into host control system and security.
Optical circuit switches, also known as all-optical switches, are optical-to-optical-to-optical (OOO) switches and are highly efficient for rapidly switching large volumes of high-bit-rate traffic between fibers and for low-latency applications. By complementing optical-to-electrical-to-optical (OEO) switching in your network with OOO switching, you will create a strong and cost-efficient set-up that enables you to “switch when you can and route when you must”.
OOO switches have a unique value proposition over traditional OEO switches, since they transmit the original input light signal through a transparent all-optical switch core – without converting it into an electrical signal and with minimal insertion loss. The transparent nature of OOO switches makes them protocol, format and data rate-agnostic.
Since they do not buffer or regenerate the optical signals, OOO switches have extremely low data latency compared to OEO switches.
An optical circuit switch enables your system to rapidly provision, protect, test and monitor vast quantities of cross-connections. This leads to maximised network uptime and increased efficiency. It also makes remote operations possible, which both reduces manpower costs and eliminates human error.
Lower total cost of ownership (TCO)
Optical circuit switching technology is future-proof, since it does not need to be upgraded or replaced as signal formats change and bit rates increase over time.
Software-defined networking (SDN)
Optical circuit switches make managing cross-connects in software-defined networks highly efficient. The switch provides the flexibility to adjust traffic flow, to accommodate increased demand while maintaining network security.
Low power consumption
With the environmental impact of data centers and IT infrastructure coming under increasing scrutiny, there are significant benefits to adopting a lower-power switching technology such as optical circuit switching wherever possible.
The POLATIS optical switching core does not rely on moving parts such as robotic arms or MEMS-mounted mirrors to create and maintain optical connections.
Instead, the HUBER+SUHNER-patented DirectLight™ beam-steering technology makes connections using compact piezo-electric actuators to align collimated beams of light from opposing arrays of input and output fibers with minimal loss, distortion or interference between paths. Alignment is maintained using feedback from integrated position sensors to ensure connection stability over time, temperature and external disturbances.
This means that, in contrast to other OOO switches, the POLATIS switching occurs completely independently of the power level, colour or direction of light on the path. This enables the switch to hold optical connections on unlit paths, which permits the pre-provisioning of dark fibers, and allows bidirectional transmission.
With its DirectLight™ optical switch technology, the POLATIS enables transparent, robust connections, even on dark fiber.
The DirectLight™ beam-steering technology sets the industry standard for highest performance and lowest optical loss.
The POLATIS® Series 6000 Optical Switch is a high-performance, fully non-blocking all-optical matrix switch available in sizes from 4x4 up to 192x192. It is designed to meet the highest performance and reliability needs of the most demanding applications with exceptionally low optical loss, compact size, low power requirements and fast switching speeds. With support of Software-Defined Networks (SDNs) via an embedded OpenFlow and NETCONF control interfaces, the Series 6000 enables extremely low latency for time-critical traffic required for new virtual cloud services in hybrid packet-optical data centers. The Series 6000 is based on POLATIS patented DirectLight™ optical switching technology that has been proven in the most challenging data center, telecom and defense applications and is also used by major network equipment manufacturers to automate testing of optical components and subsystems.
