APC

2017-10-26T16:01:32+02:00

APC DHD Series 52 modules communicate with each other via single CAT5 cables. These cables use the proprietary APC technology (Audio, Power, Control). Through APC, digital audio data and electrical power are transferred, as well as core-internal control data such as logic control, TFT control data, surface control data, firmware updates. This DHD-internal standard is not intended for use with third-party equipment.

Fibre optical connections

2022-08-11T16:40:12+02:00

Fibre optical connections DHD Gigabit Audio - GA In general, all multi-mode fibre-optic cables can be used which are recommended for “IEEE 802.3 Gigabit Ethernet (1.25GBd), 1000BaseSX”. These are the fibre-optic cable types OM3 and OM4. Cables with a core diameter of 50/125 μm and 65,5/125 μm can be used, but we recommend for cable length of more than 200 m a core diameter of 50/125 μm.
