ADOT - MC03 Network Fibre Kit - Media Converter Kit

Audiophile-grade kits to simplify the isolation of high-end audio systems using fibre optic components carefully optimised for hi-fi use.

Plug and play with no computer configuration required.

System operation is completely unchanged.

Suitable for use with all network-connected audio systems whether NAS–or streaming-based.

ADOT MC03 FIBRE NETWORK KIT (Single-Mode or Multi-Mode): 

• ADOT MC03 Media Converter
• Power Supply - Plixir BDC 2A custom built low noise PSU with three stage noise reduction. (and power supply)
• A 1.5m fibre cable
• A pair of fibre terminations known as SFP adapters

This Ethernet Media Converter by ADOT uses fibre-optic components to simplify isolation for your hi-fi system. Featuring a superior power supply, custom-built by PLiXiR. This product is designed for use with the Melco / DELA 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.

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 improves the sound quality of a network player. This is possible simply by setting a couple of switches. Internally, the construction of the kit 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. ADOT 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. 

ADOT 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 0s and 1s, 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.
