The 2408LT is an outdoor fiber optic transmitter for RF signals in the satellite L-Band or wider frequency range. It accepts a single RF input on coaxial cable and provides a single output for optical transmission. Packaged in a compact, standalone enclosure, the 2408LT is ideal for mounting on or near the satellite dish antenna structure. The -WP version features dust and water protection allowing outdoor mounting without a secondary enclosure. A full-power RF monitor output provides a convenient means of obtaining peak satellite signal strength, or additional signal distribution.
Gain may be adjusted manually or managed automatically via AGC. With SmartMON™, incoming RF signal strength, LNB current, status of connected 2400PSU-8 power supply and other data are relayed over the fiber output for monitoring through SNMP/VistaLINK® (requires SmartMON™ capable companion fiber receiver). The 2408LT also provides a DC pass through mode for LNB power and comprehensive indicators that provide status information on the input DC power and RF drive level as well as LNB power status.
