Closet-Based Switch Replacement

A solution for economical one-to-one closet-based Ethernet switch replacement that reuses the last 100m CATx cables in the horizontal, walls and drops.

The industry's only rack mountable Optical Network Terminal with 48-ports of Ethernet

It is a foregone conclusion that Optical LAN is good for new builds. However, many still believe that OLAN is not ideal for brownfield renovation projects. This is because there are false assumptions that if the last 300 feet of copper cables are not touched during a renovation, it’s easier to just refresh the traditional closet-based Ethernet switch. This untruth is perpetuated because people wrongly believe that the current form-factor of Passive Optical LAN ONTs don’t match workgroup switch footprint. They also unfortunately believe that introducing a new technology, like Optical LAN for greenfield and not brownfield, makes it difficult for the IT staff to manage two LAN technologies.

So, how can we stop this vicious cycle and start leveraging Optical LAN for newbuilds as well as renovation projects?

The Tellabs FlexSym ONT248 is the industry’s only rack mountable one-rack unit offering the delivery of 48-ports of Ethernet enabling reuse of existing cable infrastructure while providing the benefits of Passive Optical LAN.  It is compliant with ITU-T G.9807 providing XGS-PON symmetrical 10 Gbps downstream, and 10 Gbps upstream transmission. Using the Tellabs FlexSym ONT248 simplifies legacy Ethernet switch replacements, while leveraging an OLAN infrastructure.

One-for-One Legacy Switch Replace

The Tellabs FlexSym ONT248 is an economical closet-based switch replacement. It comes equipped with symetrical 10G XGS-PON and 48-ports gigabit Ethernet all Power over Ethernet (PoE) enabled. When installing the power, cable, and cable management all stays the same. Thus, you can reuse last 100m CATx cables in the horizontal, walls and drops.

Reduce Fiber Runs

Another great benefit of the Tellabs FlexSym ONT248 is how it reduces fiber cabling building-to-building and floor-to-floor. Passive Optical LAN technology is based on wave division multiplexing therefore both upstream and downstream wavelengths can be transmitted across the same fiber - lowering cabling requirements by 50%.

Extended Thermal Range

The Tellabs FlexSym ONT248 allows extended temperature range inside IT equipment rooms. That means you can follow the lead of the major data centers best practices taking advantage of natural convection cooling. This reduces the need for conditioned air in the telecommunications, thus the lower AC needs directly saves money in lower energy usage.

Lower Operational Costs

Lower annual software, support and training costs are yet one more advantage of the Tellabs FlexSym ONT248. With an Optical LAN design has fewer devices to license and Tellabs' software is sold in perpetuity elminating annual costs. Tellabs allows customers to upgrade software fixes without holding them hostage to new feature rates. Finally, traditional switch manufacturers’ annual 24X7 TAC support costs are approximately over 3x higher than Tellabs.
