3GHD-EO-2-SFP Rev. B
1 Product overview
The Flashlink 3GHD-EO-2-SFP is a 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-2-SFP the first choice for all optical transport demands.
The 3GHD-EO-2-SFP can transport all SD, HD and 3G signal formats in addition to DVB-ASI
and SMPTE310M. It performs optical refreshing and signal re-clocking, which is selectable
on application. The optical inputs are embedded in optional SFP module, which makes the
module configurable to application specific needs. The open system platform of Nevion
Flashlink system allows easy interoperability with third party fiber optical systems.
The 3GHD-EO-2-SFP unit has also two electrical outputs for each converter, which reduces
the need for additional DA’s.
