JDSU SB1C10121_17AF000FP 1x12 Single-Mode Analog Fiber Optic Switch with FC/HPC Front Bulkheads

JDSU SB1C10121_17AF000FP 1x12 Single-Mode Analog Fiber Optic Switch with FC/HPC Front Bulkheads

The JDSU SB1C10121_17AF000FP is an SB Series fiber optic switch designed for controlled optical signal routing in laboratory, production, telecom, and photonics 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, instrument, receiver, or test fixture at a time.

This configuration uses 9/125 µm single-mode fiber and supports wavelengths from 1270 nm to 1670 nm. The optical input and all 12 outputs are configured as FC/HPC bulkheads on the front panel. The part-number configuration also identifies the switch as an analog version rather than the standard return-loss version.

The 1x12 architecture is useful in systems where one optical signal must be routed sequentially among multiple paths. Controlled switching 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_17AF000FP

The JDSU SB1C10121_17AF000FP provides practical optical path selection for engineers, laboratories, production facilities, and service organizations working with single-mode fiber optic systems.

• 1x12 switch configuration: Routes one optical input to one of 12 selectable output channels.
• Analog configuration: Uses the analog SB Series option identified by configuration code A.
• 9/125 µm single-mode fiber: Supports compatible telecom, laboratory, production, and photonics applications.
• Broad wavelength range: Supports optical signals from 1270 nm to 1670 nm.
• FC/HPC optical connectors: Provides straight-contact FC interfaces for compatible single-mode patch cords.
• Front-panel input bulkhead: Places the optical input on the front panel for convenient access.
• Front-panel output bulkheads: Provides direct access to all 12 output channels from the front of the switch.
• No external pigtails: The bulkhead configuration does not require a pigtail cable-length selection.
• Controlled optical routing: Supports repeatable path selection in multi-device and multi-channel test systems.
• Reduced connector handling: Helps minimize repeated manual reconnection of optical patch cords during testing.

1x12 Optical Signal Routing

The JDSU SB1C10121_17AF000FP provides one optical input and 12 selectable outputs. The switch connects the input signal to one selected output at a time, allowing the signal to be routed toward the required device under test, receiver, detector, optical component, or production fixture.

This arrangement is useful when one laser source must be shared among multiple devices under test. It can also support systems where several optical paths must be connected sequentially to a common optical power meter, spectrum analyzer, receiver, or other measurement instrument.

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

Analog Switch Configuration

The configuration code A identifies this model as an analog SB Series switch. This distinction is important because the documented SB Series part-number structure separates the standard configuration, identified by code X, from the analog configuration, identified by code A.

The analog designation should not be interpreted as a standard return-loss specification. Exact analog control behavior, electrical interface requirements, operating levels, command functions, and supporting accessories should be verified from the individual unit and its applicable operating documentation.

Buyers integrating the switch into automated equipment should confirm the available control connections and required external hardware. These control details cannot be determined solely from the optical portion of the part number.

Single-Mode Operation from 1270 nm to 1670 nm

The JDSU SB1C10121_17AF000FP uses 9/125 µm single-mode fiber and supports wavelengths from 1270 nm to 1670 nm. This broad range covers common telecom and photonics wavelengths, including applications near 1310 nm, 1490 nm, 1550 nm, 1625 nm, and other wavelengths within the supported range.

The switch can be integrated into systems used for optical power measurement, insertion-loss testing, source distribution, receiver selection, wavelength-dependent component evaluation, and other professional single-mode applications.

The fiber type, wavelength range, connector polish, and mating interfaces should remain compatible throughout the optical system. Incompatible fibers or connectors can increase insertion loss, reduce return loss, and affect channel-to-channel measurement repeatability.

Front-Panel FC/HPC Bulkheads

The SB1C10121_17AF000FP is configured with front-panel bulkheads for the input and output ports. This arrangement provides direct access to the optical input and all 12 outputs 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 single-mode patch cords should be selected according to the connector polish and keying requirements of the complete optical system.

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

System Integration

The JDSU SB1C10121_17AF000FP is intended for integration into a professional optical test or routing system. Channel selection may be coordinated with optical sources, power meters, attenuators, receivers, spectrum analyzers, 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 analog control interface, operating signals, external cables, and supporting hardware should be confirmed for the individual unit. Only control equipment specifically identified in the product listing should be considered included.

Optical Connector Care

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