S2Net and Passive Optical Networks (PON)

Passive optical networks (PON) offer an exciting opportunity as next-generation access networks. Being cheap, high-capacity, reliable and easy to maintain, they are an attractive infrastructure option for Providers as both Copper replacement and to carry next-generation broadband services.

The S2Net network management suite recognises the importance of PON, supporting their provisioning, management and maintenance with the same power, flexibility and ease-of-use as existing infrastructure technology.

S2Net keeps you on the cutting edge of infrastructure provisioning, maximising profit and maintaining your competitive edge by managing the latest offerings in the technology-driven marketplace of today and tomorrow.

Why Passive Optical Networks?

PON are an extremely attractive option for futureaware Providers. Their main advantage over other infrastructure options are:  

  • Price – PON hardware is cheap and easy to install and manage
  • Performance – PON architecture is extremely high-bandwidth, giving maximal capacity with minimal overhead
  • Reliability – PON hardware is reliable, providing an ideal platform to maximise performance while minimising network outage.

Business Benefits for Passive Optical Networks

100% Consistent Data View – a unified, multivendor, time-spanning database improves design confidence and reduces errors, ensuring rollouts are delivered on time while minimising rework.

Sophisticated Validation – avoid errors with technology-aware and process-aware validation. All S2Net tools are driven by configurable rules to ensure your PON network is consistent and correct throughout the lifecycle of all components.

Standards-based Data – the database model is based on accepted ITU and IEEE PON standards, supporting all equipment regardless of vendor.

Automated Business Processes – S2Net streamlines provisioning through powerful rulesbased automation, letting you not only design PON infrastructure, but also its utilising services.

Open Integration – S2Net uses standard interfaces to connect with other systems, so does not lock you into a proprietary solution or prevent you from using products from other vendors. Build on your existing OSS investment.

Extensibility – extend the S2Net business, technology and engineering rules in-house to deploy new generations of PON infrastructure and utilising services quickly.

Maximise Network Utilisation – clever design algorithms locate and consume idle infrastructure to maximise network utilisation.

Maximise Reliability – S2Net reinforces the inherent reliability of PON networks with sophisticated design validation and Effect-of- Failure reports.

Vendor-independence – S2Net supports PON equipment from leading suppliers, such as Alcatel Lucent, Sony Ericsson, Nortel, Siemens Nokia, Fujitsu, NEC, Cisco and Marconi.

S2Net Support for PON Technology

S2Net supports a number of variations of the PON architecture that each rely on different technology:  

  • BPON – ATM-based PON from ITU G.983
  • GPON – Higher-bandwidth PON from ITU G.984
  • EPON – Ethernet-based PON based on the IEEE 802.3ah standards

S2Net supports all PON layers, from the physical inventory and fibre through CWDM, ATM and Ethernet to IP.

Equipment management – S2Net provides inventory support for active and passive components of a PON, including passive splitter components, cables and fibres, as well as OLT and ONT components to more complex equipment in the access network.

Fibre management – S2Net provides a fibre management layer to link with GIS-based outside plant management while managing fibre usage, terminations and other related details.

WDM management – S2Net supports all standard CWDM and DWDM wavelength designs, including the commonly used 1310/1490/1550 nm pattern shown in Figure 1 and Figure 2.

ATM layer management – S2Net supports ATM UNI/NNI as well as automatic or user-based VPI/VCI assignment at the PON ATM layer. This is important for BPON and GPON in the ATM compatibility model.

GEM layer management – This is the replacement for ATM used as a generic encapsulation layer in GPONs. S2Net manages alloc IDs and port Ids used by GEM in a PON and their unique allocation to services.

Ethernet layer management – S2Net supports VLANs for traffic separation and management of the Ethernet UNI layer. It also supports automatic management of VLAN IDs within a VLAN (PON) domain.

COS-based bandwidth management – S2Net translates user-supplied COS parameters into technology details for ATM or Ethernet, alerting you of any likely bandwidth exhaustion that may arise during the provisioning process.

Automated design – S2Net provides automated, rules-based design of services based on voice and data requirements, able to add customer infrastructure where needed (such as fibre and splitters). These designs respect PON-based limitations, such as the types of card required in an OLT/CWDM network element, or the number of splitters allowed and their possible location. S2Net automatically assigns ATM UNI/VPI/VCI values, Alloc ID and port ID for GEM, plus Ethernet UNI/VLAN IDs in the PON and elsewhere.

Address management – S2Net manages and assigns IP addresses and address pools where required in the PON network.
