Passive Optical LANs

Passive Optical LANs (POL) are fiber optic-based local area networks that offer increased bandwidth and lower TCO than traditional copper-based LANs. Unlike Cat 5, POL utilizes a fiber backbone which makes the POL network future-proof, avoiding the need for disruptive rip-and-replace approach to keep up with evolving technological requirements.

EnerSys pioneered the use of NEC Class 2 distributed power systems to bring power to the POL Optical Network Termination (ONT). The power is safely delivered over copper cables to ONTs located far from the power source. To minimize cost, the copper cables are often installed at the same time as the fiber optic cables.

The Class 2 technique eliminates the reliance on AC outlets for power and UPS systems for battery backup. It does not require installation by certified electrical personnel. This remote power method improves network reliability, simplifies installation, and lowers the Total Cost of Ownership.
