JDS Uniphase SC2F20102+27AF000FP 2x10 FC/PC Single-Mode Programmable Optical Switch

JDS Uniphase SC2F20102+27AF000FP 2x10 Single-Mode Programmable Optical Switch

The JDS Uniphase SC2F20102+27AF000FP is a rack-mount programmable optical switch designed for controlled routing of single-mode fiber optic signals. The instrument provides two optical inputs and ten selectable outputs, allowing either input to be connected to any one output through a blocking F-configuration switch fabric.

This configuration uses 9/125 µm single-mode fiber and operates across a wavelength range from 1270 nm to 1670 nm. It is suitable for optical systems operating near common telecommunications wavelengths, including 1310 nm, 1490 nm, 1550 nm, and 1625 nm.

The supplied configuration code identifies rear-panel bulkhead connections and FC/PC optical interfaces. This rear-panel arrangement is convenient for rack-mounted systems because optical cables can remain routed behind the equipment while the front-panel display and controls remain accessible.

The SC Series uses expanded-beam lens technology, precision stepper-motor positioning, and internal temperature control to provide repeatable optical alignment. The switch can be operated locally from the front panel or integrated into automated systems through its GPIB and serial RS-232 interfaces.

2x10 Blocking Optical Routing

The SC2F20102+27AF000FP provides two optical input ports and ten optical output ports. An operator or automated controller selects one of the two inputs and routes that signal to one selected output.

The instrument does not divide the selected input among multiple outputs. It also does not operate as two independent 1x10 switches. The F switch fabric creates one active connection between the selected input and output while the remaining paths are blocked.

This architecture is useful when two sources, transmitters, or reference signals must share a common group of devices under test or measurement channels. It can also route signals in systems where preventing additional simultaneous connections is important.

F-Configuration Switch Fabric

The JDS Uniphase F configuration is a blocking MxN switch arrangement. It permits any one input to connect with any selected output without establishing other optical connections.

This operation differs from the D configuration, which provides simultaneous connections between a bank of inputs and outputs. It also differs from the E configuration, which aligns other inputs and outputs with adjacent channels.

The F configuration is appropriate for source selection, receiver routing, individual component testing, and applications requiring one controlled optical path at a time.

Expanded-Beam Lens Technology

The SC Series uses expanded-beam lens technology to establish the selected optical connection. Collimating lenses direct the optical signal while a precision stepper motor aligns the selected input and output channels.

This design supports low insertion loss and repeatable channel selection without requiring external patch cords to be moved whenever the optical path changes. Internal temperature control helps maintain mechanical alignment during extended operation.

The switch is passive within the optical path. It does not generate, amplify, detect, regenerate, modulate, or convert the transmitted optical signal.

9/125 µm Single-Mode Fiber

The fiber code in the supplied configuration identifies 9/125 µm single-mode fiber. Connected sources, patch cords, receivers, detectors, components, and test instruments should use compatible single-mode fiber.

Multimode fiber should not be substituted in a precision single-mode test path. Mixing fiber types can change optical coupling, increase loss, and produce measurements that do not represent the intended optical system.

Single-mode patch cords should be routed with a suitable bend radius and protected from pulling, twisting, crushing, and repeated movement. Mechanical stress can affect transmitted power and polarization conditions.

1270 nm to 1670 nm Wavelength Range

The wavelength code F identifies operation from 1270 nm to 1670 nm. This broad range supports many single-mode telecommunications and photonics applications.

The switch can route compatible signals near 1310 nm, 1490 nm, 1550 nm, and 1625 nm. Other wavelengths within the documented range may also be used when the connected source, patch cords, devices, and receiving instruments are compatible.

Each input-to-output path should be referenced at the wavelength used for the final measurement. Path loss and connector behaviour can vary with wavelength and the complete external setup.

Rear-Panel FC/PC Bulkhead Connections

The configuration code identifies rear-panel bulkheads for both the input and output ports. This arrangement places the two inputs and ten outputs behind the instrument for structured rack and test-system cabling.

The connector code FP identifies FC/PC optical connectors. FC/PC interfaces use threaded coupling and a non-angled physical-contact ferrule.

FC/APC patch cords must not be connected directly to FC/PC bulkheads. Angled and non-angled ferrule geometries are incompatible and can cause high insertion loss, poor return loss, unstable transmission, and connector damage.

Every optical connector should be inspected and cleaned before use. Protective caps should remain installed on unused ports.

Optical Performance

For the documented two-input single-mode F configuration, typical internal insertion loss is 0.5 dB and maximum internal insertion loss is 1.0 dB. These values exclude losses introduced by the external connectors.

Typical polarization-dependent loss is 0.03 dB, with a documented maximum of 0.07 dB. Low PDL helps reduce changes in transmitted power as the input state of polarization varies.

Single-mode crosstalk is specified at a maximum of -80 dB. This optical isolation helps limit unwanted leakage from unselected paths into the active connection.

The complete performance of an installed system also depends on connector cleanliness, patch-cord quality, source stability, wavelength, polarization, receiving equipment, and external components.

Switching Repeatability and Stability

Typical sequential switching repeatability is ±0.005 dB, with a documented maximum of ±0.01 dB. Sequential switching refers to movement through channels in their normal order.

Typical random switching repeatability is ±0.02 dB, with a documented maximum of ±0.04 dB. Random switching refers to movement between channels that are not necessarily adjacent.

Insertion-loss stability is specified at ±0.03 dB typical and ±0.05 dB maximum. The documented stability specification represents the drift of a channel relative to a reference channel during a ±3 °C ambient-temperature variation over seven days.

The switch should stabilize for one hour at ambient room conditions before measurements requiring the documented optical performance are performed.

Switching Time and Operating Life

Switching time is specified at 300 ms for the first channel movement and 12 ms for each additional channel traversed. Total switching time depends on the distance between the present position and the requested position.

The SC Series switching platform is rated for more than 80 million switching cycles. This supports repetitive use in automated production, environmental testing, component qualification, and laboratory research.

Automated software should provide sufficient settling time after each switch movement before accepting a measurement from the connected test instrument.

Maximum Optical Input Power

Maximum optical input power is specified at 300 mW. The output of lasers, optical amplifiers, and other high-power sources should be measured before connection.

The 300 mW switch rating does not establish a safe input level for equipment connected to the output ports. Every detector, receiver, optical power meter, and device under test must remain within its own input-power specification.

Appropriate optical attenuation should be used whenever the source power could exceed the safe operating range of the switch or downstream equipment.

Front-Panel and Remote Control

The SC2F20102+27AF000FP can be operated locally using front-panel keys and a numeric keypad. Local control supports setup, input selection, output selection, path verification, troubleshooting, and maintenance.

GPIB and serial RS-232 interfaces support remote operation through compatible computers and test-system controllers. Automated switching can be coordinated with optical sources, power meters, attenuators, spectrum analyzers, receivers, and other instruments.

The SC Series also provides four open-collector drivers for compatible external switch modules. Each driver supports a maximum sink current of 100 mA.

Optical Path Mapping and Referencing

Both input ports and all ten output ports should be mapped before the switch is placed into service. The rear-panel labels should be compared with the active optical path reported by the front-panel display or remote interface.

A stable compatible source can be connected to the first input while a calibrated optical power meter monitors the outputs as each path is selected. The procedure should then be repeated with the second input.

The completed map should confirm every available input-to-output combination and verify that the remaining paths are blocked. This map should be retained for automation software, cable labeling, troubleshooting, and maintenance.

For precision testing, each available path should have its own reference value. The reference record should identify the input, output, wavelength, source power, patch cords, connector condition, and optical power meter used.

Measurement and Connection Considerations

The switch and connected instruments should stabilize for at least one hour before measurements requiring the documented optical specifications are performed.

Every FC/PC bulkhead and patch cord should be inspected and cleaned before connection. Protective caps should remain installed on unused ports.

The selected source and detector must be compatible with the 1270 nm to 1670 nm wavelength range and 9/125 µm single-mode fiber. Optical input power must remain below the 300 mW switch limit and within the limits of all downstream equipment.

Channel references should be checked again after any connector is cleaned, replaced, disturbed, or reterminated.

Comprehensive Functional and Performance Testing

The JDS Uniphase SC2F20102+27AF000FP receives comprehensive functional and performance testing before shipment. Testing may include AC power operation, startup, display response, front-panel controls, numeric-keypad operation, input selection, output-channel selection, blocking-path operation, GPIB communication, RS-232 communication, and available external driver functions.

Optical testing may include mapping both inputs across all ten outputs, confirming that unselected paths remain blocked, checking optical continuity, comparing relative insertion loss, verifying repeated switching, and testing representative wavelengths within the supported 1270 nm to 1670 nm range.

The rear-panel FC/PC bulkheads, alignment sleeves, connector threads, protective caps, display, controls, communication interfaces, AC inlet, cooling system, enclosure, model label, and option markings may be inspected for contamination, damage, or excessive wear.

The exact test scope depends on the available single-mode sources, calibrated power meters, return-loss equipment, polarization measurement equipment, FC/PC reference cables, communication hardware, and required channel coverage.

Calibration Before Shipment

When technically applicable and selected, the JDS Uniphase SC2F20102+27AF000FP can be calibrated or performance-verified before shipment. Evaluation may include optical path mapping, insertion loss, return loss, switching repeatability, crosstalk, switching time, and operation at selected wavelengths within the supported range.

Calibration documentation should identify each tested input and output, switch position, wavelength, optical source, reference cable, power meter, measurement procedure, recorded value, and applicable uncertainty.

Buyers requiring formal calibration should specify the wavelengths, optical parameters, input-to-output paths, quantity of tested combinations, certificate type, recorded results, and required measurement uncertainty before purchase.
