T3 Daisy Chain

The Optimux-45 DS3 fiber mux can be deployed in a daisy chain topology connecting buildings within a business park or campus. In this drop-and-insert application, the Optimux-45 DS3 fiber mux drops E1 and/or T1 services for different business entities within each building. The Optimux-45 DS3 fiber mux implements the G.747 standard to optimize fiber utilization (up to 21 E1 or 28 T1 lines per T3 link). The Optimux-45 DS3 fiber mux is connected via a T3 DS3 fiber mux to the central office/POP, where it can operate opposite a FOMi-T3 fiber modem or another Optimux-T3 DS3 fiber mux.

Market Segments

- Cellular operators

- Utilities (railways, electric companies, etc.)

- Operators serving a distant business park

- Large enterprise (e.g., university) deployed in multiple buildings

- BLEC serving multiple buildings

 

Features and Benefits

- Enables drop and insert of a combination of E1 and T1 services according to G.747 standard

- Optimizes fiber utilization by delivering 21 E1 or 28 T1 lines over a single link

- Optimizes bandwidth utilization by packing E1 (and T1) traffic onto a 45 Mbps T3 line, considering the 50 Mbsp packet size of SDH/SONET containers

- Bus topology saves cost of installing fiber links between the buildings and the POP, because one fiber cable serves all buildings in a daisy chain configuration

- Enables carriers to extend networks up to 110 km (69 miles) from central office/POP
