2 Topology Examples
This chapter provides examples of the following types of topologies and applications
x Basic topology
x Cascaded idRUs
x Master Slave topologies
x Redundancy driven topologies – RF source and dual-system redundancy driven topologies
x Special applications such as single CPRI link, idDAS for Australia, and WCS applications.
NOTE: Additional topologies are supported. Each type of topology requires the appropriate setup and
configuration procedures.
2.1 Basic Topology
This overview of a basic topology is designed to provide better understand the interoperation of the idDAS
elements. The basic topology consists of the following elements:
x 1x APOI – conditions up to 16 RF sectors
x 1x MTDI – performs RF to optic conversion for up to 16 conditioned RF band sectors
x 1x MSDH – routes the RF bands from the MTDI, towards up to 15 connected remotes. Ethernet backhaul
is routed from the each connected Ethernet port to the parallel remote unit.
x idRUs – remote units
NOTE: Each MSDH supports up to 16 standard SFPs (<10 km), where eight of the SFPs can be long range
(>10 km).
