1 Product overview
The Flashlink 3GHD-OE and 3GHD-OE-2 is a dual multi bit-rate optical to electrical 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-OE and 3GHD-OE-2 the first choice for all
optical transport demands.
The 3GHD-OE- and 3GHD-OE-2 can transport all HD and SD signal formats in addition to
DVB-ASI and SMPTE 310M. It performs optical refreshing and signal re-clocking, which is
selectable on application. The optical input comes with a sophisticated PIN diode with a
sensitivity typically better than
–20dBm operating in the 1200-1620nm wavelength range.
The module is also available as a long-haul version with typically -30dBm sensitivity. The
open system platform of Nevion Flashlink system allows easy interoperability with third party
fibre optical systems.
The 3GHD-OE and 3GHD-OE-2 unit has also three electrical outputs for each converter,
which reduces the need for additional DA’s
