Introduction
About Rattler 4
About Rattler 4
The Rattler 4 is a miniature HD/SDI to fiber optical signal converter. The Rattler 4 TX
Transmitter unit accepts a 75 ohm coaxial input and converts it into an optical signal via a
standard ST connector. The
Rattler 4 RX Receiver unit reconverts the signal back to a BNC
output.

The Rattler 4 can transmit any of the following signal types:
• 3 Gbps SMPTE 424M HD-SDI
• 1.5 Gbps SMPTE 292M HD-SDI
• 19.4 Mbps SMPTE310M
• 143 to 540 Mbps SMPTE2 59M/344M
• DVB/ASI 270 Mbps
• AES and MADI audio
• plus non-standard digital signals to 3 Gbps
The Rattler 4 is available in single and dual receiver and transmitter units as well as a dual
Transceiver unit.
Transmitters are available in standard 1310 wavelength, 1550 WDM wavelength, and
CWDM wavelengths. All 18 standard CWDM wavelengths are available. For CWDM
transmitters, an appropriate CWDM multiplexer (such as Grass Valley's passive CWDM units)
should be used to combine multiple CWDM signals from CWDM Rattler 4s and other
devices. An appropriate demultiplexer should be used (such as Grass Valley's passive
CWDM units) when using Rattler 4 receivers or the Grass Valley Python or Telethon active
demultiplexers and media converters.
Physically compact at 3.2 inches in length, the units are color-coded with Blue for Receivers
and Red for Transmitters.
All Rattler 4 units come with a permanently attached mini-XLR power connector . Power
comes from the supplied power supply or any mini-XLR jack equipped power supply
providing 5-16 volts VDC.
All units come with a set of power and signal LED indicators .
• The Receiver units have a four LED array to indicate signal strength.
• The Transmitter unit has a single LED to indicate signal presence.
