SRY-SW-L1-214 ETL StingRay200 L-band Redundancy 2x1 Switch for 1+1 Fibre Redundancy System

Product Code: SRY-SW-L1-214


Model SRY-SW-L1-214, L-band 850 to 2450MHz hot swap, redundancy switch module operating over -10 to -30dBm mean power. The module incorporates RF detection at each of its input ports and switches over if the level is outside the predefined range. It occupies one slot in a in 200 series StingRay chassis and is supplied with two link cables. The module is intended to work with ETL's splitter module SRY-DIV-L1-213.

1+1 redundancy provides resilience for uplink and downlink transmissions over fibre. This is achieved by the provision of a splitter module at the transmit end and a switch module at the receive end. If one link is broken, the signal is switched to the redundant path.

It is designed to be housed in a 200 series indoor or outdoor chassis.

The StingRay Switch module is available in a variety of RF connector types. See below for related modules and chassis.

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:

FC/APC (Angled ferrule connector / fibre connector).
Ferrule diameter: 2.5 mm
Coupling type: screw
SC/APC (Angled subscriber connector / square connector / standard connector).
Ferrule diameter: 2.5 mm
Coupling type: Snap (push-pull coupling)
