802.3bv - The Power of Plastic Optical Fiber

August 16, 2018 at 8:00 AM

 

In the realm of IEEE standards, 802.3 is bringing a lot to the table for today’s newest innovations. This standard includes several iterations that support ground breaking technology, including 802.3at and 802.3bt that support Power over Ethernet (PoE), 802.3bz that delivers 2.5 and 5 Gbps speeds over copper and now we can add 802.3bv to that list. 802.3bv was developed to support Power over Plastic Optical Fiber (POF) and it’s slated to deliver groundbreaking speed and performance.

 

First, let’s take a look at plastic optical fiber and all of its capabilities. It is a large core, step-index optical fiber capable of speeds of up to 1 Gbps. It is easy to install, cost effective, durable and is an ideal choice for networks reaching 80 meters with infrastructure that connects to switches and/or wall plates. POF will be able to meet the higher bandwidth demands of developing technology and can be used in new applications for home, industrial and automotive networks. Thus, there has been a push for the development of 802.3bv to support all of the possible POF applications.

 

The IEEE 802.3bv standard is an amendment to the 802.3 standard that allows 1000 Mb/s speeds, allowing POF to meet the increased bandwidth needs of those automotive, industrial and home network connectivity applications. 802.3bv delivers Gigabit Ethernet operation over POF and defines physical layer specs for home, industrial and auto industries. With 802.3bv, POF Ethernet networks will have the support of a robust and reliable media option. Automotive applications will have operation over a minimum of 15 meters with 4 POF connections, and distances of at least 40 meters with zero POF connections. Home and industrial applications will be able to achieve lengths of at least 50 meters with one POF connection.

 

There are three physical layer specifications in this amendment, specifically designed for the industries targeted. All use 1000BASE-H encoding over duplex POF cable and red light wavelength transmission.

 

  • ·        1000BASE-RHA – 1000 Mb/s speeds for home network and consumer applications 

 

  • ·        1000BASE-RHB – 1000 Mb/s made for industrial applications

 

  • ·        1000BASE-RHC – 1000 Mb/s rates designed for automotive applications

 

With the development of 802.3bv, yet another layer of power and possibility has been added to the realm of IEEE standards, ensuring that the world of technology has no intention of slowing down.
