SRY-RX-B2-144 ETL StingRay100 CWDM AGC Broadband Receive Fibre Converter
Description
Model SRY-RX-B2-144, 100 series CWDM (coarse wavelength division multiplexing) StingRay RF over Fibre module is designed to provide compact fibre links up to 50 km, with eight wavelengths on a single fibre cable. It is a RECEIVE module that converts an optical signal to BROADBAND (50-2450MHz).The modules has AGC (Automatic Gain Control) with automatic link optimisation for FAST SET-UP.It is designed to be housed in a 100 series indoor chassis & work with ETL's transmit modules SRY-TxxB2-143.The StingRay RF over Fibre module is available in a variety of RF connector and optical connector types. See below for related modules and chassis.
The StingRay CWDM system comprises of transmit RF over fibre modules and a multiplexer module to combine up to 8 wavelengths on to a single fibre cable at the transmit end.A demultiplexer module and receive RF over fibre modules are then used at the receive end to split the separate wavelengths. The StingRay series CWDM range of RF over fibre modules can convert L-band (850 MHz - 2450 MHz) and Broadband (50 MHz - 2450 MHz) frequencies up to 50km transmission distances. 
Fibre Connectors
Optical fibre connectors are used to terminate the end of an optical fibre cable and enables quick connection.Angle Polished Connectors
All of the connectors we offer are APC connectors (Angled Physical Contact). APC connectors are used as they provide extremely reliable way of achieving the high return losses essential in RF systems.
APC connectors have the fibre end face polished at an 8-degree angle to prevent light that reflects from the interface from traveling back up the fibre.
Due to the angle of the connector, the reflected light does not stay in the fibre core/cladding but instead leaks out into the cladding. APC connector return loss is around -60 dB.We offer 2 optical fibre connector types that offer low loss and create an extremely reliable connection:
