Simplified Architecture for Increase Reliability and Lower Power Consumption. Passive optical local area networks (POLs) can simplify your LAN. By leveraging the low losses and high bandwidth of single-mode fibers, POLs significantly reduce the cabling infrastructure and reduce the number of active devices in the network. Based on single-mode fibers and passive splitters, a POL can serve up to 7000 users over a 20 km radius with a single LAN aggregation switch. The POL’s point-to-multipoint architecture can reduce the electronics required in the LAN, leading to significant savings in power, cooling, and space requirements. Passive optical splitters enable a single optical fiber to serve multiple users. Intermediate wiring closets and workgroup switches can be eliminated. Passive fiber distribution hubs replace active workgroup switches. A single fiber can deliver signals to a local user area, where a passive fiber splitter divides the signal for delivery to individual users. This can reduce the number of cables by a factor of 32:1.
Everything You Need To Deploy an End-to-End Solution.
Save Money, Space, and Power
POLs can offer savings up to 50% in capital expenses and 75% in operating expenses over a traditional LAN. Because POLs simplify the network infrastructure, they can save you money in several ways:
- Reduced Electronics. Active network electronics are only required at each end, in the optical line terminal (OLT) and the optical network terminal (ONT). Everything in between is based on passive distribution hubs and splitters. Without the need for intermediate switches, wiring closets can either be eliminated or significantly reduced in size.
- Lower Power Consumption. The reduction active electronic equipment translates into lower power usage.
- Simplified Cabling Infrastructure. A single fiber can support up to 32 users after the splitter. Not only does this significantly reduce the number of cables that need to be run, the bend-insensitive single-mode fibers are small and easily routed.
- Easier Management. Passive optical LANs are easier to manage. The simplified architechture means moves, adds, and changes are easier than ever.
