JDSU SC1C40084 27XF003FP 1 x 8 Single Mode Optical Switch with Fiber Pigtails: Reliable 1×8 Routing for Automated Fiber Test Systems

The JDSU SC1C40084 27XF003FP 1 x 8 Single Mode Optical Switch with Fiber Pigtails is a precision 1×8 single-mode optical switch designed to route a single optical input to any of eight outputs under remote control. It is used in automated component test systems, multi-DUT production lines, and long-term monitoring setups where a single source or detector needs to address several fiber paths without manual reconnection.

Key Features and Benefits of the JDSU SC1C40084 27XF003FP 1 x 8 Single Mode Optical Switch with Fiber Pigtails

• 1×8 routing configuration — Connects one source or instrument to eight independent fiber paths, eliminating the patch-cord swaps that introduce wear and repeatability errors.
• Single-mode optimized — Designed for 9/125 µm telecom fiber, with low insertion loss and high return loss across the C- and L-bands.
• Fiber pigtail interface — Direct pigtails avoid the connector-pair losses introduced by mated bulkhead designs, preserving budget in sensitive measurements.
• Low insertion loss — Keeps the switch's contribution to the test path small enough to characterize low-loss components without correction math.
• High repeatability between switch cycles — Returns to the same insertion loss on every actuation, which is critical for automated test routines that rely on stored calibration values.
• Long operational lifetime — Rated for millions of switching cycles, suitable for production environments where the switch operates continuously for years.
• Remote control interface — Driven through standard digital control lines for direct integration into automated test executives.
• Compact form factor — Fits into rack-mount enclosures and OEM test fixtures without consuming valuable bench space.

Advanced Capabilities

The value of a high-quality optical switch in an automated test system is often underestimated until repeatability problems start to show up in the data. Every time a switch actuates, its internal mechanism — typically a moving prism, mirror, or fiber alignment block — has to return to a position that matches the calibration done at system setup. If repeatability is poor, the loss budget through the switch drifts between cycles, and a 0.1 dB switch drift turns into a 0.1 dB measurement error on every device under test. The SC1C40084 holds repeatability tight enough that automated systems can be calibrated once and trusted for thousands of measurements.

The pigtailed configuration is the other engineering decision worth highlighting. Adding connectors at the switch ports introduces two extra mated pairs in every signal path, each contributing typically 0.2–0.5 dB of additional loss and a reflection that limits ORL performance. Direct pigtails sidestep both problems: the user can splice or terminate the fiber leads in the configuration that best fits the application, whether that means fusion-spliced inline connections in a permanent system or custom connectors chosen to match the rest of the test bench.

Calibration and Quality Assurance

Every JDSU SC1C40084 27XF003FP is calibrated prior to shipping to OEM specifications. The order includes a Calibration Certificate, Calibration Label, and full Calibration Data. This means the switch arrives traceable, audit-ready, and ready to use straight out of the box — no need to schedule a calibration cycle before putting it into service.
