I just discovered this Wireless Network Technology, Today. The Association for Passive Optical LAN (APOLAN), a non-profit organization dedicated to driving the adoption of passive optical local area network technologies. Sounds very interesting. Check out the info and links, below...

Why Passive Optical LAN

Optical Line Terminal

The Optical Line Terminal (OLT) resides in the datacenter or core network. It connects to the core switch using traditional Ethernet pluggables.

Consists of modular PON cards
Provides redundant switching, control, and power capability
Each PON port typically connects 32 ONTs
Transmits Ethernet to end user ONTs on one wavelength (1490 nm)
Receives Ethernet from end user ONTs on a separate wavelength (1310 nm)
Utilizes 128 bit AES encryption for downstream (broadcast) traffic
Utilizes Time-Division-Multiple-Access (TDMA) for upstream traffic

Passive Optical Splitter

Passive Optical Splitters connect to each PON port and replicate traffic downstream (to the end user's ONT) while combining end user traffic in the upstream direction.

Requires no power or cooling (hence the word "passive")
Can be placed anywhere in the midspan of the fiber network
Typically deployed in above-ceiling fiber zone boxes near end user work areas
No need to perform cross connects after initial installation (networks are logically assigned)
The splitters and fiber components will last for decades

Optical Network Terminal

The ONT serves as the end user interface to the network.

Typically powered by a low voltage power brick
Converts the single mode fiber optical signal to RJ-45 Ethernet interfaces
Various models provide anywhere from 1 to 24 Ethernet Ports
Various models support Power-over-Ethernet (POE)
Supports VLAN, 802.1x, and QoS
Can be deployed on the desktop, wall-mounted, or rack-mounted

How to Build A Passive Optical LAN (Local Area Network)

Posted on November 8, 2016 by FS.COM

Local area network (LAN) is being widely deployed in the enterprise, university, hospital, army, hotel and places where a group of computers or other devices share the same communication link to a server. Most of the traditional LAN are based on Ethernet copper cable. As more and more devices and cables are adding to the existing copper based LAN, problems come out. Bottlenecks of bandwidth, cabling space, cable infrastructure are limiting the network services. To better organize the local area network and ensure the network performance, passive optical LAN based on optical fibers, also known as POL, is being deployed.

Passive Optical LAN VS. Traditional LAN
