Advantages of Passive Optical LAN

Optical Fiber connections can travel much more distance (up to 20 KM) when compared to copper-based connections (up to 100 meters), without needing any form of re-transmission. The core (aggregation) fiber switch can accommodate more than 7000 IP connections. The distribution layer uses passive optical splitters which do not need power (the entire distribution layer can be done away with, in some cases).

Since the distribution layer can be eliminated/doesn’t need to be powered, this architecture saves a lot of cables, space, wiring closets, power points, cooling costs, electrical costs, etc. Passive Optical LAN can handle high-bandwidth connections with real-time traffic. Each end-point can be provided with more than 1Gbps of bandwidth.

The Work Group Terminals, which connects the optical network to the RJ-45 end-point copper ports, coming in POE versions, as well. Passive Optical LAN is a carrier-class solution – It is already being used to provide network connectivity to individual homes. Hence, the technology is tested and reliable.

POL equipment manufacturers claim that both capital costs and maintenance costs are cheaper than copper networks. POL manufacturers claim that optical network is more secure than copper networks because information cannot be ‘tapped’ by capturing the electromagnetic radiation emitted (as in the case of copper cables). POL supports common security standards like AES, 802.1x, etc.

POL vendors claim that it is relatively greener as the solution uses less electrical power. Passive Optical LAN for enterprises has been standardized. Optical Fiber cables need not be changed every now and then to support higher bandwidth, unlike copper cables that need to be changed. For fiber networks, only the active components may require up gradation to support higher bandwidth.

Single vendor solution means single management interface and easier management/learning-curve (when compared to managing multiple switches manufactured by different vendors on a traditional LAN). POL can handle both IP voice and TDM phone connections using the same network. Good option for organizations that are based over a large area (educational institutions, hospitals, etc). Bend-resistive fiber cables are available for effective inside-building optical fiber cabling.
