A Deep Dive into the Technical Advantages of Passive Optical LAN

A Deep Dive into the Technical Advantages of Passive Optical LAN

Earlier this year, APOLAN conducted its member survey to determine the top three benefits of POL adoption. They found that wireless synergies, technological superiority and investment protection topped the list of the key factors influencing decision-makers to choose Passive Optical LAN (or POL) for their LAN upgrades and new builds.

We recently shared an in-depth look at POL and wireless innovations in a recent blog post, “A Closer Look at Passive Optical LAN’s Synergy with Wireless Innovations.”  For our second installment of the POL benefits series, we are diving deep into the technology side of POL.

Here are the top technical advantages that decision-makers can benefit from when adopting POL as their network infrastructure of choice.

All Services Needed, One Network: Converging all network services is an important value-add feature of POL. The technology enables all services to be delivered across a single infrastructure, eliminating the need for multiple platforms while providing highly scalable, high-speed data services to all users. Voice (e.g., analog POTS and VoIP w/PoE), video, video conferencing services, WiFi and cellular access, and monitoring services (e.g., building automation system, security cameras and building sensors) are all supported with POL. In addition, streamlining all network needs into a single backbone delivers network simplicity and creates time-saving opportunities for IT teams.

The Cornerstone to Success – Availability and Scalability: To keep up with growing connectivity needs, modern network backbone technologies need to deliver scalability to accommodate more bandwidth needs as well as availability that keeps business going, with no unplanned interruption. In both situations, passive optical LAN provides superior rates when compared to copper-based LAN.

Going the Distance: Composed almost entirely of single-mode fiber optic cable, a POL can span for 20 km (12.5 miles) or more depending on the optics and splitter ratios deployed. Copper has a limitation of merely 300 feet. While not all networks may need to span such distances, it is particularly advantageous for multi-story buildings and campus networks where mid-span switching equipment is eliminated entirely. Even single building networks can take advantage of these flexible distances by no longer requiring a telecommunications closet or switch every 300 feet as is the case with legacy network architectures.

Future-Ready For Whatever Comes Next: As a single-mode fiber (SMF) infrastructure, POL virtually future-proofs a network. With its capacity to carry 101 Tbps of full-duplex bandwidth, SMF enables technology upgrades without requiring replacement of the cabling infrastructure, the most expensive part of the upgrade. POL extends the network lifecycle to 10 years or more, enabling gradual, more predictable costs for bandwidth upgrades over the lifetime of the network. 

Unmatched Security: With early adopters being the U.S. federal government and the U.S. Department of Defense, POL is a proven, highly secure technology. In comparison to copper-based LANs, POL reduces the number of vulnerable access points to which hackers have access. In addition, POL produces no EMI radiation and its ONT component does not store configuration or user information and requires no physical management access. Plus, with low human touch operations, POL is far less susceptible to human error, or negligent and malicious human activities.
