7705OE-HD HDTV Optical to Electrical Converter, 19.4Mb/s to 1.5Gb/s
Revision 1.6 7705OE-HD - 1
1. OVERVIEW
The 7705OE-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 7705EO-HD Electrical to Fiber converter facilitates conversion from coaxial distribution at
the source. The converter features one optical input with three re-clocked serial digital outputs. The
7705OE-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.
The 7705OE-HD is available in 2 different versions with different optical input sensitivity. (See
specifications for complete information)
7705OE-HD -15 dBm input sensitivity
7705OE-HD-L -22 dBm input sensitivity
