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 directed to one connected device, instrument, 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 input and output ports are configured as FC/HPC bulkheads located on the front panel. The switch also uses 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 test paths. Controlled switching can reduce repeated fiber reconnections, protect optical interfaces from unnecessary handling, and improve consistency during component characterization, production screening, system verification, and multi-channel measurement procedures.

1x12 Multimode Optical Signal Routing

The JDSU SB1C10121-22XB000FP provides one multimode optical input and 12 selectable outputs. The switch connects the input signal to one selected output at a time, allowing the optical signal to be routed toward the required device under test, receiver, detector, component path, or production fixture.

This arrangement is useful when one optical source must be shared among several devices under test. It can also support systems where multiple optical paths must be connected sequentially to a common detector or measurement instrument.

A 1x12 optical switch can improve test efficiency by reducing the need to disconnect and reconnect fibers between measurements. Controlled switching can also improve setup consistency and reduce wear on optical connectors during repetitive test procedures.

62.5/125 µm Multimode Fiber Configuration

The JDSU SB1C10121-22XB000FP uses 62.5/125 µm multimode fiber. This fiber configuration should be matched with compatible multimode sources, patch cords, receivers, detectors, and other optical equipment.

Multimode measurements can be affected by launch conditions, modal distribution, source characteristics, fiber length, connector alignment, and bending. Consistent patch cords and launch conditions should be used when comparing measurements among the 12 output channels.

This model should not be described as a 9/125 µm single-mode switch. The fiber code in the supplied part number identifies the installed configuration as 62.5/125 µm multimode fiber.

750 nm to 940 nm Wavelength Range

The wavelength code B identifies the 750 nm to 940 nm range for compatible multimode configurations. This range supports near-infrared optical routing for laboratories, component testing, source distribution, detector evaluation, and other multimode applications.

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

The exact optical performance of a configured system also depends on the source launch, patch-cord construction, connector condition, modal distribution, detector area, and condition of the internal switch paths.

Front-Panel FC/HPC Bulkheads

The SB1C10121-22XB000FP is configured with front-panel bulkheads for the optical input and outputs. This arrangement provides direct access to the input and all 12 output channels without requiring rear-panel fiber routing or permanently attached pigtails.

The FC/HPC connector 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 system.

FC/HPC interfaces should not be mated directly with FC/APC connectors. Straight-contact and angled-contact connectors have different ferrule end-face geometries, and direct mating can damage the interfaces or produce poor 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, and automated production equipment.

In an automated system, one optical source can serve several test paths through the switch. The system controller 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 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 12-output switch contains multiple optical interfaces, making a consistent inspection and cleaning process 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 optical path performance, channel repeatability, insertion loss, 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 connection, 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.

The SB1C10121-22XB000FP should not be confused with a similarly numbered 9/125 µm single-mode configuration. The fiber code 2 and wavelength code B identify this unit as a 62.5/125 µm multimode switch 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.
