Transceivers Introduction Optical switches POLATIS technology overview Direct light technology POLATIS all-optical switches (OOO) enable data center operators to make and change single or multiple cross-connects on the fly securely, remotely and from anywhere as part of an SDN-enabled network. The patented DirectLight® (1) beam-steering technology at the core of POLATIS optical switches makes connections between opposing arrays of input and output fibers with minimal loss, distortion or interference between paths and switching occurs completely independently of the power level, colour or direction of light on the path. POLATIS optical switches are agnostic with regard to data rates and protocols and can hold dark fiber connections.

Optical power monitoring is used where the data center operator wants to monitor either an absolute loss of signal or a relative degradation of signal over time, which might indicate an optical component is beginning to fail. The user can set alarm conditions for either application in the switch software. Optical power monitors are also deployed when the optical switch is being used as a qualified optical demarcation point between different carriers’ liabilities.
