The SVLAN values are configured from the SDN software.
They use a single SVLAN tag for business customers that passes through the OLT and ONU. Our OLT strips the SVLAN tag and the ONU strips the CVLAN tag. For high speed internet, they use a single VLAN per OLT port and a CVLAN for the ONU on the OLT.
#VIRTUAL ARCHITECT FOR MAC SOFTWARE#
The Virtual OLT software communicates to the OLT modules and ONUs over via dedicated VLANS per OLT port (Layer 2 Ethernet OAM). Switches and Routers can provide the data plane for the OLT while a software function is required to merge the single OLT ports and numerous ONUs into a logical OLT system and tie it together with the other data plane devices. The Tibit MicroPlug module can provide a single PON port of a Virtual OLT. This document gives an overview of the system requirements to provide a PON access solution using the Tibit MicroPlug OLT module.įigure 4: Virtual OLT software architecture The MicroPlug allows the operator to flexibly select the architecture that fits the requirements. The Tibit MicroPlug does not require or dictate a particular architecture. Existing OLT blades can achieve higher density and greater flexibility by using the Tibit MicroPlugs locally or remotely. The PON modules provide standard compliant interfaces that allow for compatibility with many readily available ONUs and ONTs on the market.Ī PON access system can be created by combining the Tibit OLT module with a Network Function Virtualization Software layer, Ethernet Routers, Ethernet Switches, and other white box solutions. Tibit provides both EPON and GPON PON flavors of the modules at 10Gbps speeds. The Bridge chip contains an embedded processor to allow for in-band module control and configuration locally or remotely over an Ethernet switching infrastructure. An integrated Bridge chip allows the Tibit MicroPlug module to connect a PON Network to a point-to-point Ethernet SFP+ socket that is commonly found on Ethernet switches, routers, and many other optical networking devices. In all cases, the Tibit OLT Module provides the application specific portion of an OLT in a single pluggable form factor. Additionally, the Tibit OLT module can be used to create forward looking Virtual or Distributed OLT system solutions. Tibit OLT modules can be used to create higher density or more flexible versions of today’s integrated solutions. The Tibit MicroPlug Modules are key pieces of technology in the design of a next generation OLT.
