Installing POF in the home is very fast and simple but, like other communication installations, it should be verified. The typical way to confirm that the installation is working is to check the link LED indicators. But this provides no indication of how well or how badly the POF link is working. It makes a difference because optical communication suffers attenuations from the fiber length, bending, a bad cut or bad insertion. An installation working close to the sensitivity limit may fail in the future due to small extra attenuations (aging, thermal changes, equipment is hit, etc.)

In order to ensure that the installation has been done properly and is operating with a sufficient margin, checking the link quality is recommended. This video demonstrates the KDPOF debugging tool. It allows monitoring of the POF links in an installation where a KDPOF daisy-chain outlet is used. The monitor application will give information about the outlet ID, operating time, connected ports speed and, of course, the link margin of the optical ports.

List of materials used in the video:

  • 2x POF media converters + PSUs
  • 1x POF daisy chain outlet + PSU
  • POF cable
  • 2x laptop
  • 1x STB
  • 3x UTP cable
  • KDPOF monitoring tool

Installing POF will help to improve the Internet connectivity in the home. A POF link can cover up to 50 m, giving 1 Gb/s performance. The installation does not require high-level skills and can be done with simple tools. POF cable is typically installed through the existing conduits in the house, so it’s easy to reach any room and keep the cable hidden.

This video shows how to connect and check a point-to-point (P2P) POF link by using commercial media converters. Key points are the simplicity and quickness of the cut and connect. The media converter consists of one RJ45 copper port and one optical POF port. It allows the implementation of a P2P link which can cover, for example:

  • Improve wireless connectivity of the furthest room: [Router] <-> POF <-> [WiFi Access Point]
  • Move the router to the optimum place: [ONT] <-> POF <-> [Router]

List of materials used in the video:

  • 2x POF media converters + PSUs
  • POF cable
  • POF cutter
  • 2x laptops
  • 2x UTP cable

At the virtual WEKA Bordnetz-Kongress 2020 (Wire Harness Congress) on September 22, 2020, KDPOF displayed insights and update on Optical Multi-Gigabit Connectivity. Juergen Schachtschneider, Automotive Manager Central Europe & Greater China, and César Esteban, Applications & Support Manager, presented how automotive networks profit from optical technology. Electric and autonomous driving architectures are substantially pushing the challenges for wiring systems. Issues include electromagnetic interference (EMI), electromagnetic susceptibility (EMS), and weight reduction. On top, automotive applications, utilization, and safety requirements are boosting the necessary network speed tremendously. The new 48-volt electrical architecture in cars additionally pushes the envelope in terms of cross-domain isolation requirements. Copper links for communication rates above 100 Mb/s need heavy and expensive solutions to comply with the stringent OEM’s EMC specs, resulting in high cost and very difficult engineering. Moreover, the weight of the ever-growing diameter of the required cables plays against the race for range increase of electrical powertrains.

Optical network technology overcomes these trends thanks to its inherent galvanic isolation, robustness, low cost, and low weight. Carmakers will benefit from optical links for communications between the 48-volt and the 12-volt domains. For weight, the optical network will save more than 30 percent of the equivalent copper-based harness weight. Optical Ethernet provides 100 Mb/s and 1 Gb/s network solutions today, and multi-gigabit Ethernet is the significant upcoming breakthrough for in-vehicle networks. The standardization effort for optical multi-gigabit is already in progress within the IEEE as an amendment to the Ethernet standard 802.3.

The installation does not require high level skills and can be done with simple tools. POF cable is typically installed through the existing conduits in the house, so it’s easy to reach any room and keep the cable hidden.

This video shows how to connect and check a daisy-chain (DC) POF installation by using commercial equipment. Key points are the simplicity and quickness of the cut and connect. The daisy chain POF outlet consists of two RJ45 copper ports and two optical POF ports. It allows installations in DC topology, which can cover multiple rooms.
