The objective of this video is to provide a solid understanding of Passive Optical LAN or POL. The topics addressed include a definition for POL, the basic components of a POL network, the history and evolution of POL and a description of the technology used in POL interfaces.

[Limited Availability] The Tellabs FlexSym Singlemode to Multimode 2x8 Splitter enable the cost-effective re-use of existing multimode fiber infrastructure inside buildings and across campuses. Tellabs FlexSym SM-MM 2x8 Splitter is ideal in scenarios where there is SMF cabling between buildings and MMF cabling within buildings. It also can be used when SMF cable is between main data center (MDF) to telecom closet (IDF) and MMF cable runs from telecom closet through-out access network (i.e. horizontal and drops).
Eliminates the cost of installing new singlemode fiber in the horizontal pathways and the final access drops
Supports any length of singlemode fiber from the Tellabs OLT to the splitter up to the limit of the 28dB optical budget
Supports OM1, OM2, OM3, and OM4 multimode fiber cabling
Completely passive operation with no power or maintenance required
Allows re-use of multimode fiber cabling from the splitter location to where the ONTs are mounted
Available in both 2x8 and 2x16 splitter versions
Optional support for Type-B PON redundancy adding additional resiliency to the network design
Allows full rate G-PON service over MM fibers up to 550 meters
@bhardy - We have rolled the 180C out to several sites as part of the limited availability process but field testing and feedback is not yet complete. We have not declared GA on this product yet but will keep you posted.
The Tellabs CER Data Utility is provided to facilitate the importing of data into the Cisco CER (Cisco Emergency Response) system. The utility will query the targeted OLTs LLDP data and retrieve equipment data that matches a specified system description name. This utility will perform a one-time execution (and data retrieval). The Windows system scheduler must be used if the utility needs to be executed at regular intervals.
This utility does not perform the import into the Cisco CER system. After the utility has been executed and the data has been obtained, separate steps to import the data into the Cisco CER must be taken.
Tellabs OLT SR29.2 or above and any EMS version are supported.
For installation, configuration and utility execution instructions, please reference ENG-010609.

Dante Audio Equipment
Dante Audio equipment is a commonly used protocol for distributing audio in large venues. Dante requires time synchronization for proper operation. It also is a very heavy user of multicast for almost all its messaging and streams. This allows all the nodes to stay in sync and audio output to be time wise synchronized.
This document defines how to configure the Tellabs equipment to optimize the Dante Equipment for maximum Scalability and reliable operation.
Key Optimizations Checklist
The following section summarizes the key configurations needed for proper Dante Operation on a Tellabs Optical LAN:
- Dante segregation to its own VLAN
- Use of CBR1 (CBRrt) with > 16 Mbps of Bandwidth
- Disable ONT Discovery on PONs with Dante Active
- Change PTP responses to Unicast on Dante
- Primary and Secondary timing source should be above the OLT.
- Manage CBR bandwidth based on network needs
- Mark Dante traffic with high priorities
Multicast In OLAN
OLAN systems are optimized for downstream multicast (Network Interface to ONT UNI direction). Multicast is less efficient when sent in the upstream direction. Within the PON where multicast is sourced, copies must be sent to ONT UNIs on that PON that are on the Dante VLAN. Many of the optimizations stated below attempt to minimize individual copies of multicast packets that need to be sent within a PON when a source is sending multicast upstream.
