JDS Uniphase SA Series SA-Z491 (8×8)

The JDS Uniphase SA-Z491 is an 8×8 optical switch designed for telecommunications and networking test environments requiring precision fiber routing and signal distribution. This fiberoptic unit combines relay and precision stepper motor switching architecture with configurable direct-drive lines, enabling group or individual channel operation via front-panel controls or remote command interfaces.

## Technical Specifications

The SA-Z491 accommodates single-mode fiber at 9/125 µm with FC/PC or SC/PC connectors. Switch control operates through IEEE 488.1 parallel and RS232C serial interfaces, with front-panel numeric keypad access for channel selection and configuration management. Non-volatile memory supports STORE and RECALL functions for switch and driver settings.

Power requirements: 110/115/230/240 V AC at 50–60 Hz, single-phase, maximum 100 VA consumption. Optional 48 V DC @ 2 A supply available. Fusing: 5×20 mm, T1.6A/250V time-delay. Main supply voltage must remain within ±10% of nominal.

## Key Features

• 8×8 matrix switching architecture
• Single-mode fiber compatibility (9/125 µm)
• Dual-interface control: IEEE 488.1 and RS232C
• Front-panel step-up/step-down channel selection
• Address selection and return-to-local functionality
• Configurable relay and stepper motor drive lines
• Non-volatile configuration storage
• Low-voltage AC/DC dual-supply operation

## Typical Applications

Optical test labs, telecommunications network validation, fiber-optic signal routing, system integration test benches, and multi-wavelength signal distribution in enterprise and laboratory environments.

## Compatibility & Integration

IEEE 488.1 GPIB and RS232C connectivity enable instrument-level integration into automated test systems. Local front-panel control accommodates manual operation and verification workflows. Single-height chassis with optional connector panels support flexible optical interface configurations.
