At the point several years ago when my digital streaming experience had begun to step up to the next level, I still was pretty much oblivious to the need for outboard improvements. For me, that was initially the big selling point of ethernet to fiber conversion – lowering the noise floor. Home Ethernet equipment and cabling can easily introduce unacceptable levels of digital noise into your playback environment. That is, to implement complete protection of your Ethernet-connected equipment from network-related lightning damage, which can be an extremely vexing problem in any audio setup. And although my previous goal for setting up an Ethernet to fiber conversion scheme was strictly to improve sound quality, that’s recently been augmented by another, previously unknown (to me, at least) rationale for this setup. I’d been reading about the ease of incorporating one for probably nearly four years now, but for whatever reason, my interest had never been taken to the next level, until just last week, when I caved and spent the $90 necessary to make it happen, at my local Micro Center. One of them involves my current subject, which is employing a Gigabit Ethernet media converter setup in combination with my digital streaming system. Trust me, I’ve been there, done that!Īnd along the way, some of the most useful hacks and hardware ancillaries intended to elevate the performance of digital music streaming have seemed to elude me, for whatever reason. Dealing with the hardware configurations isn’t horrific, it’s mainly the buggy, mind-numbingly stressful DLNA or UPnP open source software implementations needed to create a working music server. ![]() At almost ten years into this voyage, my personal experience tells me that the DIY route is not for the faint-of-heart. But my initial involvement with digital audio was more as a tinkerer, and there’s a whole cottage industry of home-brew designs (mostly based on Intel NUC or Raspberry PI configurations) out there. Recently, I’ve had the good fortune to evaluate several exceptionally good turnkey streaming setups, including the Euphony Summus Server/endpoint system that is the cornerstone of my home system. KDPOF's transceiver for Ethernet over POF, the KD1053, is optimised for low power and small footprint and transmits data at 1000/100Mbps on standard SI-POF, MC-POF, or PCS, according to 1000BASE-RH (IEEE 802.3bv).I’ve been involved in digital music streaming for around eight or nine years now, but have only truly taken a really deep dive in the last few years. ![]() This solution is mainly aimed at the highly controlled environment of data centres, and does not meet automotive norms.Ĭonsequently, the first choice for battery management systems is Gigabit Ethernet POF (GEPOF), which perfectly meets the requirements of carmakers by providing high connectivity with a flexible digital host interface, low latency, low jitter, and low linking time. Looking at optical connections, Glass Optical Fibre (GOF) does not provide enough margin for automotive requirements. "This is a tough requirement that is very hard to reach without a nearly perfect isolation that copper-based networks are unable to ensure," added Carlos Pardo.Ī low cost and low performance means to achieve galvanic isolation is an opto couplers based solution, which is rather unreliable and offers very limited speed performance. Galvanic isolation is also necessary between the primary and secondary systems of both AC/DC and DC/DC converters due to the presence of hazardous high voltage (above 25VAC or 60VDC).Īccording to the FMVSS 305 and ECE-R standards, the isolation barrier between battery and exposed conductive parts should maintain 500Ω/V before and after a crash impact. The lack of galvanic isolation between the domains of a battery management system causes a serious threat to the user and a source of severe damage to the electromechanical parts of the car. ![]() In addition, they are easy to upgrade to 1000Mbps when a higher data rate is required. ![]() Optical connections with POF provide the optimal means to achieve galvanic isolation, providing 100Mbps Ethernet compatible solutions with enough margin to withstand the harsh automotive environment.
