Passive Optical LAN has clear economic advantages over traditional enterprise networks. These savings are seen for both capital and operational costs. Often the lower costs are a result of Passive Optical LAN (POL) ability to:
- Centralize intelligence and management
- Remove telecommunications rooms (i.e. IDFs, wiring closets)
- Reduce the need for midspan electronics, power, and cooling infrastructure
- Use smaller, lighter, less expensive cables to reduce pathway and space requirements
- Eliminate the need to refresh cabling infrastructures
The Association for Passive Optical LAN (APOLAN) Technology Committee members recently completed a POL cost comparison study. They did so by analyzing the cost of POL parameters (e.g. 4-port PoE ONTs, ONTs shared in cubicles, 2×32 splitters, zone box solution and no TRs) versus those of traditional parameters (e.g. 48-port PoE switches, One 10G uplink per TR, stacked switches and 2 CAT6 drops per user). The comparison was then built-out to represent one 4-story building with 90 users per floor, one 7-story building with 150 users per floor, and four 6-story campus buildings with 180 users per floor (POL cost comparison graph download provided below).
The resulting POL cost comparison savings identified during this exercise are as follows:
- POL saved 40% cost for the 4-story building with 90 users per floor
- POL saved 55% cost for the 7-story building with 150 users per floor
- POL saved 56% cost for the four 6-story campus buildings with 180 users per floor
Please note that all costs are representative estimates only and not quotes or guarantees. Actual costs will vary based on numerous factors including, but not limited to, geographic region and local market issues.
