OVERVIEW
The 2405OE Fiber to Electrical converter provides an economical method of converting incoming optical
distribution for SMPTE 259M (143 - 360Mb/s) serial digital signals to in-plant coaxial distribution. The
companion 2405EO Electrical to Fiber converter facilitates conversion from coaxial distribution at the
source. The 2405EO is ideal for use in portable, remote and link extension applications where the small
size, rugged enclosure and high performance operation meet the stringent requirements of these
applications.
The 2405OE converter features one optical input, one coaxial input with two re-clocked serial digital
outputs. A coaxial SDI input can be used as a fallback source, in case of optical link failure or can be
selected as the primary input. It has been designed to be used primarily as a reclocking SMPTE 259M or
DVB-ASI distribution amplifier and converter, however SMPTE 310M (19.4 Mb/s) signals can also be
reclocked.
Features:
•
Reclocking for all SDTV video rates including SMPTE 259M (143Mb/s-360Mb/s), SMPTE 344M
(540Mb/s), DVB-ASI (270Mb/s) and SMPTE 310M (19.4Mb/s)
•
Independent isolated output drivers to ensure no cross channel loading effects and maintain polarity
from input to output for DVB-ASI applications
•
Operation with multi-mode or single-mode fiber
•
SC/PC, ST/PC or FC/PC connector options
•
Comprehensive signal, laser and modules status indicator LEDs
•
Rugged, small form factor enclosure
•
Low power +12 VDC operation
