COMMUNICATIONS COMPONENTS
Key Features • 1x1, 1x2 (2x1), and 2x2 latching configurations
• Compact and suitable for PCB mounting
The JDSU SN Series fiberoptic switch is GR-1221 qualified and designed for use
in central office network applications. This reliable, miniature optical component
is available as a 1x1 (on/off), 1x2, and 2x2 switch.
Collimated lenses and a moving mirror minimize insertion loss and improve the
repeatability and stability of the switch parameters. The switch itself is directly
mounted on printed circuit boards (PCBs), and is equipped with status contacts
to provide an electrical readout of the switch position. Latching operation ensures
that the switch remains in position following power loss.
On request, JDSU also provides customized modular assemblies that incorporate
taps, wavelength division multiplexers (WDMs), splitters, and other components.
Applications
• Network switching in central office
environments
• Optical network protection and
restoration
• Configurable optical add/drop
• Transmitter and receiver equipment
protection
Compliance
• Telcordia GR-1221-CORE and
GR-1073-CORE
