Dual Channel Optical to Electrical Converter

SAMIM OED-3904 is a converter of digital video signals on a fiber optic link to 3G/HD/SD-SDI/ASI electrical signals. This card can be used along with electrical to optical signal converter cards on the receiver side. The OED-3904 features are input signal detection, two converters on one card, input fiber link detection, loss compensation, input re-clocking. According to link distance, it provides different SFP with various input sensitivity.


The OED-3904 is a converter of optical digital video signals to 3G/HD/SD-SDI/DVB-ASI electrical signals. The module can receive two video signals over fiber optic links via an SFP and provide four electrical outputs per channel. The OED-3904 performs automatic input signal detection, and two conversions on a single board. Users can use different SFPs with various sensitivity and wavelengths related to the link length and transmitter power.

This module operates in two modes of 1 to 8 and 2 to 4. For the 1 to 8 mode, the input 1 is converted to electrical signal and then is connected to all eight outputs. For the 2 to 4 mode, the input 1 is connected to the first four outputs and the input 2 is connected to the second four outputs. In this mode, changeover option is available. When the changeover is enabled, if one of the input signals is lost, its corresponding outputs are fed by the other input. All adjustments and controls can be applied directly by onboard DIP switches and the web-based user interface. LED indicators on the front edge of the module, inform the user about operational status of the module.
