Tellabs unveils enhanced PON Protection

May 13, 2020
Tellabs' enhanced PON Protection functionality provides for fiber route diversity and OLT redundancy across the optical distribution plant of an enterprise network.

Tellabs, a specialist in passive optical network (PON) technology, announced that the Tellabs FlexSym Series, and its System Release 31.3 (SR31.3) Advanced Availability Software Package, is now available and supports enhanced PON Protection functionality.

The company says its enhanced PON Protection provides for fiber route diversity and optical line terminal (OLT) redundancy across the optical distribution plant of an enterprise network.

By utilizing 2:x passive optical splitters, typically with 2:16, 2:32, 2:64 split ratios, Tellabs says its PON Protection functionality provides the highest degree of network uptime availability with: protection across two PON service cards in a single OLT chassis; and protection across two PON service cards in geographically dispersed redundant OLTs.

Additionally, Tellabs FlexSym Series SR31.3 Advanced Availability Software Package adds an innovative new feature called “PON Path Protection.”

With PON Path Protection, the system software proactively monitors the path’s health across the network, and if it detects the OLT has lost connectivity to the network, it will automatically switch to protection. This enables the ability to route traffic around a network failure by shifting traffic to the standby PON.

"No other enterprise optical LAN equipment manufacture has this capability," states Tellabs.

Further, the PON Path Protection feature adds the capability to detect the failure of major card-level components and intelligently switch to the optimal path. This ensures uninterrupted traffic flow of real-time and critical business services. It also allows for the failed card to be replaced in a maintenance window without affecting any network uptime availability.

“Simply stated, the enhanced PON Protection functionality enables our enterprise optical LAN customers to reduce the LAN downtime impact on their employees and business operations by eliminating lost employee productivity, and lost connectivity to corporate resources and e-commerce,” comments Rich Schroder, Tellabs president and CEO.

Schroder adds, "The financial gains for our customers relative to operating their business with the highest degree of network availability are tremendous."
