- Combines optical fibre technology with IP/Ethernet technology
- Provide traffic management and multiplexing features within any overall fibre or WDM connection
- May include layer 2 networking features such as VLAN tagging
- May include service adaptation features such as legacy SDH & PDH conversion
- May include very low speed traffic management such as telemetry
Packet optical systems is a carrier class technology that provides a successor to previous generations of carrier fibre networking systems such as SDH, PDH & PCM services that have often supported applications such as telephony, SCADA and low speed data.
Packet optical connections can also be used to provided leased line connections operating at sub-wavelength rates, typically at less than 10Gb/s.
Packet optical platforms often incorporates advanced traffic management, network monitoring, network protection and add-and-drop multiplexing.
Packet optical systems often provide support for legacy TDM and low speed connections that are found in utility networks. These are converted from their native synchronous nature to modern packet-switched service connections. Utility industries often require connections for special devices such as pumps switches and sensors. Carrier features such as synchronisation (for mobile networks) are usually supported.
Each of these network features is combined onto fibre and WDM connectivity systems for transmission to other network locations.
Packet switching technologies are usually found within carrier networks where a wide range of service types need to be supported.
