Features

• Supports any length of SMF from the Tellabs OLT through the splitter up to the limit of the 28dB optical budget
• Allows re-use of multimode fiber cabling from the splitter location to where the ONTs are mounted (all Tellabs ONT models are supported)
• Economical one-to-one MMF cabling solution without stranding ports on passive optical splitters
• Eliminates the cost of installing new singlemode fiber in the horizontal pathways and the final access drops
• SMF SC/APC connector on OLT/splitter side and MMF LC/UPC connector on ONT side
• Allows full rate PON service over multimode fiber cabling up to 550 meters
• Qualified for OM1, OM2, and OM3 multimode fiber cable types
• Completely passive operation, no power or maintenance required

Features

Smart
It is a mode adapting jumper cable that has Singlemode Fiber (SMF) connector to the passive optical splitter facing the Optical Line Terminal (OLT). This allows for the operation of 10G XGS-PON and 2.5G G-PON over Multimode Fiber (MMF) between the jumper and the Optical Network Terminals (ONT). The Tellabs FlexSym SMF-MMF Modal Adapter Cable has unique underlying technology that cancels modal dispersion association with MMF transmission.

Stable
The Tellabs FlexSym SMF-MMF Modal Adapter patch cord can work in conjunction with 2:x passive optical splitter to provide industry leading fiber route diversity and geographically dispersed OLTs using FSAN-based Type-B PON redundancy. This redundancy provides for port-to-port, card-to-card, OLT-to-OLT and PON Path protection switching. Network redundancy is an optional architecture for when the highest level for resiliency is required.

Scalable
The SMF-MMF Modal Adapter cable can scale enterprise LAN infrastructure regardless of SMF or MMF cabling. Existing MMF cabling can be repurposed to reach ONTs mounted in telecom rooms (intermediate distribution frames) within a building, and ONTs mounted in plenum space, above ceilings, below ceilings, in walls, in office cubicles or at desks, or even in main distribution frames in the main data centers of remote buildings – all Tellabs ONT models are supported.

Savings
With the Tellabs FlexSym SMF-MMF Modal Adapter cable, installations gain all the benefits of a Passive Optical Network, while economically using MMF cabling solution without the need to replace the MMF with SMF cabling. Furthermore, the one-to-one MMF cabling solution saves costs by not stranding ports on passive optical splitters.
