OVERVIEW
The 2405OE-HD Fiber to Electrical converter provides an economical method of converting incoming
optical distribution for SMPTE 292M (1.5 Gb/s) HDTV serial digital signals to in-plant coaxial distribution.
The companion 2405EO-HD Electrical to Fiber converter facilitates conversion from coaxial distribution at
the source. The converter features one optical input with two re-clocked serial digital outputs. The
2405OE-HD has been designed to be used primarily as a reclocking 1.5Gb/s distribution amplifier,
however, it can also be used as a non-reclocking SMPTE 310M (19.4 Mb/s), DVB-ASI, or SMPTE 259M
(143 to 540 Mb/s) distribution product.
Features:
•
Reclocking mode for SMPTE 292M (1.5 Gb/s) signals
•
Non-reclock mode for SMPTE 310M (19.4 Mb/s), SMPTE 259M (143 to 540 Mb/s) or DVB-ASI, or
most other bit rates less than 1.5 Gb/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
•
Low power +12 VDC operation
