ADOT Fibre Optic Gigabit Network Conversion Kit MC01/02/03
This suite of Ethernet Media Converters by ADOT use fibre-optic components to simplify isolation for your hifi system. The MC01 kit features the Media Converter, two SFP's, a 1.5m fibre cable and a basic power supply. The MC02 features the same, but with a linear power supply. The MC03 features a superior power supply, custom-built by PLiXiR. This product is designed for use with the Melco S100 or other switches with SFP ports. For use with systems that do not feature SFP connections, you will need to additionally purchase the MC Accessory.
FutureShop's Expert Review of the ADOT Fibre Optic Gigabit Network Conversion Kit
ADOT's demonstrators used a contemporary favourite for testing: Birds by Dominique Fils-Aimé. Its minimalist instrumentation and Dominique's panned layered vocals filled the stereo image. Feeding our Melco N5 streamer, we began with the MC02's linear power supply. Compared with listening with no ADOT at all, it instantly made the song punchier with more powerful lower-mids; vocal layers began pleasantly separating.
Swapping to a single-mode cable dug deeper still into the mix, splitting apart the tonal range of Dominique's overdubbed lines. As we further upgraded our ADOT setup, we discovered just how much was going on with the subtleties of the track's percussion. The delicate nuances of the percussive taps revealed how dynamic the production of this music was. As always, we removed everything and listened again to hear what we missed – flatter, sluggish-sounding audio. To read the full review, visit our blog.
What ADOT say
Designing a fibre unit for hi-fi systems is a challenge. Because fibre is used in IT systems primarily for speed, and hi-fi doesn’t need fibre for speed, it needs it for clarity!
In fact, reducing the comms speed of the MC01 to 100Mb/s improves the sound quality of a network player. This is possible simply by setting a couple of switches. Internally, the construction of MC01 is to Enterprise Standards and this extends to the massive Ethernet magnetics that couple to the copper part of the network.
SFP adapters
There are many choices of fibre configuration and wavelength (colour) of the optical transfer. Audiophile DOT simplifies the decision by supplying a matched pair of Duplex SFP adapters with matched fibre.
Fibre
The fibre has to match the design parameters of the SFP adapters and so the Duplex fibre that is supplied is paired with the SFP adapters. Connectivity of the fibre adapters is critical and the terminations are all factory-made in clean-room conditions. 1.5m lengths mean that the devices can be tucked out of the way behind a hi-fi system.
There is a limit of several hundred metres for the fibre link. The fibre is also less than 3mm in diameter, and so is ideally suited for making the connection between the router and the hi-fi system, even in the largest homes or between buildings.
Audiophile DOT can supply standard lengths of optical fibre up to 50m; all are clean-room-assembled with individual performance tables supplied with each cable.

Why upgrade?
Analogue audio is delicate. Digital audio is just as delicate, plus digital data needs to be treated with the utmost respect to achieve the results that today’s high-resolution digital music files promise.
The reason is simple.
Behind the 0’s and 1’s, hi-fi electrical signals are still analogue, and just as susceptible to the influence from noise and interference. This additional noise damages the integrity of the pulse edges. This uncertain transition point, of a noisy pulse edge, results in timing errors and jitter. Using a high-performance audiophile data switch, such as the Melco S100, ensures that the data is as pristine as possible and switch management ensures that errant data packets are not presented to the hi-fi system. But, the Ethernet cabling is still a risk, being connected to noisy IT-type devices in the home and the cable is also an effective antenna, capturing EMC from the environment. Copper wire, used for Ethernet cables, is effective at conducting data, but is equally effective at conducting all manner of interference as well.
The solution is simple too.
By breaking the conducted signal, we remove the interference and isolate the hi-fi system. This is done with fibre optics––now the data can be communicated to the digital components, but without any risk of introducing any conducted interference and noise.
The basic Audiophile DOT MC01 Fibre kit comprises of:
- A single Audiophile DOT Media Converter (and power supply)
- A 1.5m fibre cable
- A pair of fibre terminations known as SFP adapters
Simple power supply upgrade options:-
The MC01 kit
Good level of isolation. Supplied as a complete kit with a universal voltage power adapter
The MC02 kit
Better level of isolation. Supplied with a linear power supply that ensures no additional noise is generated
The MC02 DUAL kit
This comprises of the MC02 kit and the MC Accessory (listed below). It is effectively and MC02 designed for compatibility with non-SFP devices.
The MC03 kit - NP or PLIX
The ultimate solution, supplied with a NuPrime LPS-205 linear power supply (MC03 NP), or a custom build PLiXiR Elite BDC 2A low noise power supply with 3 stage noise reduction (MC03 PLIX).

MC Accessory
A kit to allow MC series kits to be used with network switches that do not have SFP ports. Systems that do not have a Melco S100, will require a second media converter, available as an accessory to the main kit. This applies to installations using network players that normally simply connect to the residential network. Includes single MC01 Media Converter, power adapter lead to use existing power supply of MC01/02/02 kit, and 1m Melco CAT7 Ethernet Cable.

"...there is a greater sense of openness in the presentation and with it greater clarity, contrast and subtlety. All of which combines to produce a result that is closer to analogue than can usually be achieved with streaming services; it’s arguably not as good as locally stored music but good enough to enjoy at a proper volume level."

"The ADOT fibre kit brought an upgrade to my system better than achieved with a network switch at the same price. It delivers greater transparency and resolution from the streaming system regardless of the music source. Results will vary with the situation, but from where I sit ‘this is a definite contribution to road safety’, which – for those not well-dipped in 1980s British TV nostalgia – translates to 'it works damn well."

"I don’t just like the ADOT MC-01, I like it a lot. It has greatly enhanced my enjoyment of music and for those who already own a network switch that has an SFP input, it’s the proverbial ‘no brainer’. For those that do not own such a device, I would definitely recommend trying the MC-01 with the MC Accessory Kit, especially if you need long runs of cable from your router to your switch and indeed if you need to run that feed near power cables or other potential sources of electrical interference."
