Tellabs, a provider of passive optical LAN (POL) technology, is at the 2018 BICSI Winter Conference in booth #1201, showcasing a demonstration of a Tellabs Optical LAN system operating the 2.5G ITU G.984 PON protocol simultaneously over a common optical distribution network supporting symmetrical 10G ITU G.989 PON.
The Tellabs demo is powered by communications networks specialist Alpha Technologies, with testing and monitoring provided by EXFO. According to Tellabs, "This industry-first display proves that customers deploying today’s PON technology can support future bi-directional 10 Gigabit connectivity speeds over the same infrastructure without the disruptive rip-and-replace that happens with traditional copper-based IT networks."
Per a press release describing the demo, "The Tellabs Optical Line Terminal (OLT) and Optical Network Terminals (ONT) demonstrates that 2.5G ITU G.984 PON simultaneous over a common optical distribution network supporting 10G ITU G.989 PON can be delivered via the same system, and better yet, from the same PON service module." Tellabs reiterates that the demo "shows how today’s PON users can upgrade to future 10G connectivity speeds without having to replace existing equipment, cabling, splitters and powering systems."
“Our symmetrical 10 gigabit OLAN solution strategy is that it minimizes the impact on our existing customers and ensures today’s infrastructure is leveraged," comments Jim Norrod, Tellabs' president and CEO. "That means that the investment in existing single-mode fiber and passive optical splitter installed inside buildings and across campus network is protected. We are on pace to deliver the latest 10G PON technology, in the best form-factor, utilizing the least amount of power and providing the best cost value to our customers. This is a true breakthrough when compared to the disruptive rip-and-replace that occurs with legacy copper-based IT networks.”
In the demo, the Alpha Technologies eLimiter+ Class 2 Remote Power Distribution Unit showcases the ability to remotely power 10G ONTs along with today’s PON architectures.
“The eLimiter+ provides users with the ability to avoid costly and cumbersome AC power at the ONT. The Class 2 design meets NEC requirements, increases overall network reliability and lowers the total cost of ownership,” comments Grant Clark, Alpha Technologies' vice president of product management and development. “It’s exciting to provide part of the infrastructure continuity that enables POL networks to deliver more bandwidth in the future.”
For its part in the demo, EXFO’s new PON Power Meter - PPM-350D - demonstrates accurate and simultaneous power level measurement of downstream and upstream signals supporting wavelengths for both next-gen PON and legacy GPON.
“EXFO’s innovative PPM-350D automatically detects and adjusts to the standard thresholds for next-gen and legacy passive optical network technologies, ensuring error-free readings for the service installers,” comments Stephane Chabot, EXFO’s vice president, test and measurement. “Seeing our test solutions in action over a real XGS-PON setup is a great opportunity for our customers to witness the interoperability of EXFO’s innovations with a system vendor such as Tellabs.”
