Abstract
An optical communications network comprising a Head End Unit connected to a plurality of groups of Network Termination Equipments (NTE) and/or Optical Network Units (ONU), wherein downstream communication is by Time Division Multiplex, wherein a group is multiplexed onto a stream and a plurality of streams are combined into a higher speed multiplex and upstream communication is by Time Division Multiplex Access is characterized by enabling the NTE's or ONU's to negotiate bandwidth in respect of low level upstream traffic and by pre-allocating bandwidth to individual NTE's or ONU's in respect of high level upstream traffic.

An optical communications network, comprising:
- a head end unit connected to a plurality of groups of network termination equipments (NTE) and/or optical network units (ONU), wherein downstream communication is by time division multiplex, wherein one of the groups is multiplexed onto a stream, wherein a plurality of streams is combined into a higher speed multiplex, wherein upstream communication is by time division multiplex access, wherein a broadcast channel is transmitted once and once only to all recipients on all the streams, wherein one of said NTE and said ONU comprises a broadcast comparator for checking all the streams for broadcast cells, and wherein any of said NTE and/or ONU is operative for extracting broadcast traffic from any of the streams.
