1 Product overview
The Flashlink 3GHD-EO and 3GHD-EO-2 is a single or dual multi bit-rate electrical to optical
converter module providing high performance media conversion for various signal formats
from 19.4Mbps up to 2970Mbps. Unmatched signal accuracy, even in critical applications
with pathological signal patterns makes the 3GHD-EO and 3GHD-EO-2 the first choice for all
optical transport demands.
The 3GHD-EO and 3GHD-EO-2 can transport all HD and SD signal formats in addition to
DVB-ASI and SMPTE310M. It performs electrical equalizing and signal re-clocking, which is
selectable on application. High quality optical transmitters using FP or DFB lasers are
suitable for short and medium haul applications. The open system platform of Nevion
Flashlink system allows easy interoperability with third party fiber optical systems.
The two modules also support Fibre breakage detection signalling. This feature allows for the
user to distinguish between a loss of signal at the input of the transmitter and a fibre
breakage towards the receiver.
The 3GHD-EO and 3GHD-EO-2 unit has also two electrical outputs for each channel, which
reduces the need for additional DA’s. The electrical input is equipped with a multi rate cable
equalizer providing an equalization of typically 75m of high quality coax cable at 2970Mbps.
