Tellabs FlexSym Series is a future-proof architecture with unlimited capacity

Tellabs FlexSym Series, a symmetrical 10 gigabit XGS-PON solution that provides significantly more flexibility to design an enterprise Local Area Network (LAN) for both commercial and federal government customers. The Tellabs FlexSym solution provides the unique ability to serve both 10G and G-PON on the same system, and even on the same PON service card, providing infinite options and a graceful migration to future higher speed network needs.

 

With the Tellabs FlexSym solution, IT professionals, architects, consultants and engineers now have the tools to build enterprise networks flexibly to support current network speed requirements and scale up to 10 gigabits of symmetrical connectivity. FlexSym allows LANs to be more efficiently designed by minimizing network footprint, power and costs compared to legacy copper-based networks.

Tellabs FlexSym offers improved flexibility in LAN architecture and a graceful migration to future network demands by providing the following benefits.

 

  • Select XFP-based 10G XGS-PON and 2.5G G-PON at OLT
  • Choose G-PON ONTs and XGS-PON ONTs where needed
  • Mount ONTs in telecom closets and extend ONTs deep in buildings
  • Optical distribution network split ratio can be up to 64 wide splits
  • Single or dual feed Type-B PON protection for fiber route diversity
  • Extend 1G, 2.5G, 5G and 10G Ethernet speeds from the ONTs
  • Built-in reserve capacity to grow network density, and speeds
  • Software Defined LAN functionality today
  • Path to 100G network uplink and 40 gigabit NG-PON2 for the future

 

 

Quick Facts

 

  • 10 gigabit XGS-PON provides symmetrical transmission speeds.

 

  • Designed taking into account future generation wavelength impacts to ensure no wavelength conflicts.

 

  • Current single-mode fiber cabling and passive optical splitters support next-generation 10G PON and beyond.

 

 

  • Upgrade to Tellbs FlexSym Series 10G XGS-PON can be done on a per ONT (per super-user) basis.

 

  • ONT’s powering and space requirements are inline with today’s existing deployments levels.

 

  • Single-mode fiber has no known capacity ceiling.

 

Symmetrical connectivity

 

XGS-PON is defined as part of the ITU-T G.9807.1 (physical layer), G.987 (.2/.3/.4) and G.988.1. XGS-PON provides symmetrical (e.g. 10 Gbps downstream and 10 Gbps upstream) transmission, which is a hard requirement for true enterprise Passive Optical LAN.

 

Fiber’s unlimited bandwidth

 

Fiber optic cabling knows no upward limit to its capacity. Currently, fiber optic cable bandwidth records are hitting Petabyte speeds, which is a thousand times faster than Terabyte capacity.

 

Use 10G only where 10G is truly needed

 

It is a fact that 10G consumes more energy, is larger and costs more. Thus, it is best to be strategic as to what truly requires 10G connectivity. The good news is that upgrades to next-generation 10G XGS-PON can be done on a per ONT (per super-user) basis.

Compatibility with today’s infrastructure

 

Tellabs’ 10G XGS-PON solution takes into consideration both current and future impacts for system wavelengths, powering and space so as to eliminate any conflicts. Furthermore, current single-mode fiber cabling, passive optical splitters and fiber management infrastructure supports all generations of PON, including G-PON, XGS-PON and NG-PON.

 

Software Defined Networking

 

Tellabs Optical LAN is ideal choice for SDN. OLAN already matches SDN intent and already supports SDN like functionality today. 10G OLAN implementation will be the first step towards open-source and standards-based SDN.

 

Tellabs R&D leadership

 

Tellabs has a track record of deploying evolutionary PON technologies and scaling these technologies to millions of ports of PON.
