JDSU SB1C10121_22XB000FP 1x12 Multimode Fiber Optic Switch with FC/HPC Front Bulkheads

JDSU SB1C10121_22XB000FP 1x12 Multimode Fiber Optic Switch with FC/HPC Front Bulkheads

The JDSU SB1C10121_22XB000FP is an SB Series multimode fiber optic switch designed for controlled optical signal routing in laboratory, production, research, and automated test systems. It provides one optical input and 12 selectable output channels, allowing a single optical source or signal path to be connected to one device, detector, receiver, or test fixture at a time.

This configuration uses 62.5/125 µm multimode fiber and supports wavelengths from 750 nm to 940 nm. The optical input and all 12 outputs are configured as FC/HPC bulkheads on the front panel. The model also incorporates the standard SB Series return-loss configuration identified by code X.

The 1x12 architecture is useful in systems where one multimode optical signal must be routed sequentially among several optical paths. Controlled channel selection can reduce repeated patch-cord changes, protect optical interfaces from unnecessary handling, and improve consistency during component characterization, production screening, system verification, and multi-channel measurement procedures.

Features and Benefits of the JDSU SB1C10121_22XB000FP

The JDSU SB1C10121_22XB000FP provides practical optical path selection for engineers, laboratories, production facilities, and service organizations working with multimode fiber optic systems.

• Reduced connector handling: Helps minimize repeated manual reconnection of sources, detectors, and devices under test.

1x12 Multimode Optical Routing

The JDSU SB1C10121_22XB000FP connects one optical input to one selected output channel. The remaining output channels are not part of the active optical path until selected by the switch control system.

This configuration is useful when one multimode source must serve several devices under test. It can also be used where multiple test paths need to be connected sequentially to a common detector, receiver, or measurement instrument.

Automated or controlled path selection can improve test throughput by reducing manual fiber changes between measurements. It also supports more consistent test configurations by maintaining permanent connections between the switch outputs and the associated devices, fixtures, or measurement paths.

62.5/125 µm Multimode Fiber Configuration

The fiber code in the JDSU SB1C10121_22XB000FP identifies 62.5/125 µm multimode fiber. The switch should be used with compatible multimode optical sources, patch cords, detectors, receivers, and other system components.

Multimode measurements can be affected by source launch conditions, modal distribution, fiber length, connector alignment, bending, and patch-cord construction. Consistent launch conditions and matching fiber types are important when comparing optical performance among the 12 output channels.

This unit should not be described as a 9/125 µm single-mode switch. The fiber code 2 identifies the installed optical configuration as 62.5/125 µm multimode fiber.

750 nm to 940 nm Wavelength Range

The wavelength code B identifies the supported range from 750 nm to 940 nm. This range is intended for compatible multimode applications and supports near-infrared optical routing within laboratory, production, sensor, detector, and component test systems.

The optical source, detector, fiber, and connector interfaces should all support the intended operating wavelength. Equipment designed exclusively for longer telecom wavelengths may not provide appropriate performance in the 750 nm to 940 nm range.

Complete system performance also depends on the source launch, fiber modal distribution, patch-cord condition, connector cleanliness, detector area, and condition of the internal switch paths.

Front-Panel FC/HPC Bulkheads

The JDSU SB1C10121_22XB000FP uses front-panel bulkheads for the optical input and all 12 outputs. This arrangement provides direct access to every optical channel without requiring rear-panel fiber routing or permanently attached pigtails.

The FC/HPC configuration uses straight-contact FC interfaces. Compatible FC/PC or FC/HPC multimode patch cords should be selected according to the connector polish and keying requirements of the complete optical system.

FC/HPC connectors should not be mated directly with FC/APC connectors. Straight-contact and angled-contact connectors use different ferrule geometries, and direct mating can damage the interfaces or degrade optical performance.

System Integration

The JDSU SB1C10121_22XB000FP is intended for integration into a professional multimode optical test or routing system. Channel selection may be coordinated with optical sources, power meters, receivers, detectors, attenuators, fixtures, and automated production equipment.

One optical source can serve several test paths through the switch. A compatible control system selects the required output before initiating a measurement on the connected component or optical path.

The required control interface, command set, external cables, and software should be confirmed for the individual unit. These electrical and control details cannot be determined solely from the optical configuration portion of the model number.

Optical Connector Care

All FC/HPC connector end faces should be inspected and cleaned before connection. Dust, residue, scratches, or damaged ferrules can increase insertion loss and produce unstable measurements.

Protective caps should be installed on unused input and output ports. A 1x12 switch contains 13 optical interfaces, so a consistent inspection and cleaning process is important for reliable channel-to-channel operation.

Patch cords should be routed with appropriate bend-radius control and strain relief. Excessive bending, pulling, or lateral force at the front-panel bulkheads can affect optical performance or damage the patch cords and switch interfaces.

Comprehensive Functional and Performance Testing

Formal metrology calibration may not be applicable to every fiber optic switch configuration. When calibration or optical characterization is technically applicable and supported, the JDSU SB1C10121_22XB000FP is calibrated or characterized before shipment. This process may include evaluation of channel repeatability, insertion loss, optical path performance, and switching operation.

Following successful calibration or characterization, the equipment may include a calibration label, calibration certificate, and related test data, depending on the switch configuration and selected service.

If formal calibration is unavailable or not applicable, the switch receives comprehensive functional and performance testing. This process may include verification of the input port, all 12 output channels, channel selection, optical continuity, connector condition, available control functions, and supported optical performance.

This testing helps verify that the switch operates correctly and that its available functions have been evaluated before it is released for shipment. The exact test scope, optical data, documentation, and included service records should be confirmed before purchase when these items are required for laboratory, production, regulatory, or quality-management applications.

Buyer Considerations

The JDSU SB1C10121_22XB000FP is a configuration-specific multimode fiber optic switch. Buyers should confirm that the 1x12 architecture, 62.5/125 µm multimode fiber, 750 nm to 940 nm wavelength range, FC/HPC connectors, standard return-loss configuration, and front-panel bulkheads match the intended optical system.

This unit should not be confused with a similarly numbered 9/125 µm single-mode configuration. The fiber code 2 and wavelength code B identify the SB1C10121_22XB000FP as a 62.5/125 µm multimode switch designed for the 750 nm to 940 nm range.

Buyers should review the condition of the input and all 12 output interfaces, channel-selection operation, control connections, enclosure, power requirements, included cables, and available test results before purchase.
