Upgrading telephone exchanges

For its ongoing BTOpenreach program BT chooses Prysmian Group as its preferred partner to turn an innovative OCR Exchange concept into reality. BT and Prysmian Group co-designed the OAsys Optical Consolidation Rack to upgrade BT telephone exchanges around the country.

Special feature – they allow splicing of network fibre to pre-connectorised cables thus avoiding the need for individual cable jumpers. The OCR is a splice-only solution for FTTH PON networks with multiple customers on the same fibre to eliminate congestion. Delivered in a flat pack format the units can be assembled easily by one person.

The OCRs accommodate up to 8 sub-racks with 12 pull-out modules and 6 splice trays. Their total capacity allows 1152 fibres on a dual fibre per tray basis.
