Evertz Microsystems 2408LT L-Band/Wideband Standalone Fiber Transmitter Series
Fiber link provides electrical isolation between antenna and facility mitigating ground loop and lightning issues
2408LT L-Band/Wideband Standalone Fiber Transmitter Series
The Evertz 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 super compact, standalone enclosure, the LT series is supreme 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 ultimate 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 2408 series 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.
For GPS applications, 2408LT13-5V-B50 can be used to power-up GPS antenna with 5V supply and transport GPS signals over fiber when combined with 2406LR-5V-B50 receiver
