Free Space Optics (FSO) Installation

Only digital transport can utilize free space optics for building-to-building links where fiber is either not available or cannot be deployed in a timely or cost-effective manner. Free space optics distances are determined by service level availability, but are typically in the range of 500 meters to 1 kilometer.

Wave Division Multiplexing (WDM)

InterReach ICS typically is transported over dedicated strands of fiber (a pair of fiber for transmit and receive paths.) Because of the digital transport, ICS can utilize WDM technology, essentially combining two waves to one, reducing the required fiber count by half. Optical budgets will be dependent on the added losses with WDM (the passive modules and added connectors) and the selection of the SFP transceivers.

Pay As You Grow

Expansion units can be added as growth or capacity needs change by simply adding additional transceivers, expansion units or remote units. Expanding the InterReach ICS system does not require adding splitters at the host location or re-optimization as long as the RF parameters remain the same. Conversely, non-utilized ports can simply be shut off without affecting system performance.
