The plastic optical fiber featured a 2.2-mm diameter and a 1-mm core. Telefónica described the fiber as easy to install; it required a simple cutter and obviated the need for connectors. The result was an installation cost “considerably lower” than conventional glass fiber, in the words of a Telefónica press release. The fiber will support transmission rates of 1 Gbps, the company added (see “IEEE 802.3bv specifies Gigabit Ethernet capabilities for plastic optical fiber”).
In the trials, which included approximately 30 homes, the instal
lation elements included the fiber and a media converter with the KDPOF chipset inside it. The media converter contains the plug and two Ethernet ports to enable the connection of a pair of fiber branches (see photo above).
The comparatively low cost and ease of installation are benefits plastic optical fiber proponents have touted for decades (see, for example, “Proponents hope home is where the plastic is”). The technology has been proposed for data center and enterprise network applications as well as home entertainment networks; automotive, aircraft, and shipboard use; and industrial networks.
Telefónica did not reveal deployment plans. The service provider says it also tested 60-GHz WiFi technology that it asserts could support capacity as high as 4.6 Gbps.
