3GHD-EO-D15xx Rev. 2

1 Product overview

The Flashlink 3GHD-EO-D15xx.xx is a single 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-D15xx.xx first choice for all optical
transport demands.

The 3GHD-EO-D15xx.xx 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 narrowband temperature stabilized
+5dBm DWDM DFB lasers. 3GHD-EO-D15xx.xx is suitable for medium and long haul
applications. The open system platform of Nevion Flashlink system allows easy
interoperability with third party fiber optical systems.

The 3GHD-EO-D15xx.xx unit has also two electrical outputs, 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.

1.1 Constraint on number of cards in a frame

Only 5 cards with DWDM transmitters should be assembled in one Flashlink
frame (FR-2RU-10-2). This constraint applies for both PWR-AC15/15/5/5V and
PWR-AC-75W, in single and redundant power configuration.

This constraint applies also regardless of the normal power consumption of the card, as it is
related to the start current at power up.
