JDSU OAB1564+20FP0 C+L-Band In-Line Erbium-Doped Fiber Amplifier with FC/PC Connectors

JDSU OAB1564+20FP0 C+L-Band In-Line Erbium-Doped Fiber Amplifier

The JDSU OAB1564+20FP0 is a benchtop erbium-doped fiber amplifier designed to amplify compatible single-channel optical signals across the C-band and L-band. Configured as an in-line EDFA with FC/PC optical connectors, it supports telecommunications system testing, optical component characterization, amplifier emulation, subassembly manufacturing, and photonics research.

The OAB1564 operates across two documented wavelength regions: 1530 nm to 1560 nm in the C-band and 1570 nm to 1600 nm in the L-band. This dual-band capability allows one amplifier to support testing across a broad portion of the erbium amplification window.

The amplifier provides greater than 14 dBm of saturated output power and greater than 20 dB of small-signal gain under the specified measurement conditions. Its noise figure is less than 6.5 dB, while polarization-dependent loss is specified at 0.4 dB or less and polarization mode dispersion at 0.7 ps or less.

A user-friendly front panel includes an LCD for input and output power information, current control, and access to the optical interface. The compact half-rack benchtop enclosure can also be installed in a standard 19-inch equipment rack using the supported rack-mount kit.

C+L-Band Optical Amplification

The OAB1564 is designed to amplify optical signals across both C-band and L-band wavelength regions. Its documented operating ranges are 1530 nm to 1560 nm and 1570 nm to 1600 nm.

This broad spectral coverage supports optical transmission and component testing at multiple telecommunications wavelengths. It can be used with compatible sources, receivers, attenuators, switches, couplers, filters, and optical spectrum analyzers operating within the supported bands.

The wavelength range contains a gap between 1560 nm and 1570 nm. Performance within this interval should not be assumed from the documented C+L-band designation.

In-Line Amplifier Configuration

The OAB1564 is configured as an in-line optical amplifier. An in-line EDFA can be used to emulate amplification within an optical transmission system, compensate for path loss, raise the power of a low-level signal, or characterize the effects of amplification on connected components and receivers.

The amplifier is intended for compatible single-channel optical signals. Performance with multichannel DWDM loading should not be assumed from specifications provided for the OAB1564 single-channel configuration.

A complete test system may include a tunable or fixed-wavelength source, variable optical attenuator, optical switch, power meter, optical spectrum analyzer, receiver, and other compatible equipment.

Saturated Output Power

The documented saturated output power for the OAB1564 is greater than 14 dBm. This value is measured at 1550 nm with an input level of -4 dBm and at 1590 nm with an input level of 0 dBm.

Saturated output power describes amplifier performance when the EDFA is driven into a high-output operating region. Actual output power depends on wavelength, input power, amplifier condition, control settings, connector loss, and the connected optical path.

The output should be measured before the amplifier is connected to a sensitive detector, receiver, power meter, or optical spectrum analyzer. External attenuation may be required to protect downstream equipment.

Small-Signal Gain

The OAB1564 provides greater than 20 dB of small-signal gain under the documented test conditions. Small-signal gain is measured with an input level of -20 dBm.

This gain level allows the amplifier to raise low-power optical signals for system, receiver, and component testing. Available gain can vary with wavelength, input power, output loading, amplifier settings, and optical path loss.

A stable source and calibrated optical power meter should be used when measuring amplifier gain. The input and output readings should be taken at the same wavelength and under stable operating conditions.

Noise Figure

The documented noise figure for the OAB1564 is less than 6.5 dB when measured with an input level of -20 dBm. Noise figure indicates the amount of noise added by the amplifier relative to the optical input signal.

Noise performance is important in transmission experiments, receiver sensitivity testing, amplifier cascades, and component characterization. The observed system noise also depends on the source, measurement bandwidth, optical spectrum analyzer settings, external loss, and connected components.

Noise figure measurements require a suitable optical source, optical spectrum analyzer, reference procedure, and calculation method. An output power reading alone is not sufficient to determine noise figure.

Polarization Performance

Polarization-dependent loss is specified at 0.4 dB or less for the OAB1564. PDL describes the variation in transmitted optical power caused by changes in the input state of polarization.

Polarization mode dispersion is specified at 0.7 ps or less. PMD describes differential delay between polarization modes and can affect high-speed optical transmission systems.

The complete test setup may introduce additional PDL and PMD through patch cords, connectors, couplers, switches, attenuators, and devices under test. System-level measurements should account for all components in the optical path.

Input and Output Isolation

The OAB1564 provides documented input and output isolation of 40 dB and 40 dB. Optical isolation helps reduce unwanted reverse-propagating signals and reflections that could affect amplifier stability or connected sources.

System isolation also depends on connector condition, external isolators, return loss, patch cords, and the reflection characteristics of downstream devices.

FC/PC Optical Connectors

The FP connector code identifies FC/PC optical interfaces. FC/PC connectors use a threaded coupling mechanism and non-angled physical-contact ferrules to provide secure optical connections.

Compatible FC/PC single-mode patch cords should be used at the amplifier input and output. FC/APC connectors must not be directly intermated with FC/PC interfaces because their ferrule geometries are incompatible.

Every optical interface should be inspected and cleaned before connection. Contamination can increase insertion loss, create reflections, reduce available output power, destabilize measurements, and damage mating connector end faces.

Front-Panel Monitoring and Control

The OAB Series provides a front-panel LCD that displays input and output power information. This helps users monitor the optical levels entering and leaving the amplifier during setup and operation.

The front panel also provides current control and access to the optical interface. The amplifier should be operated according to the installed controls, displayed status, and applicable safety procedures.

External calibrated optical power meters should be used when traceable input and output measurements are required. Built-in monitor values are useful for operation and troubleshooting but should not be substituted for formal calibration unless supported by the required test documentation.

RS-232 Remote Control

The OAB Series supports RS-232 remote control for integration with compatible computers and automated test systems. Remote operation can coordinate amplifier settings and monitoring with sources, switches, attenuators, power meters, spectrum analyzers, and receivers.

Communication cables, software, drivers, command documentation, computers, and automation programs should be considered included only when specifically identified in the product listing.

Measurement Setup and Operation

The amplifier should be placed on a stable bench or installed using compatible 19-inch rack-mount hardware. Ventilation openings should remain unobstructed, and the unit should be operated within the supported temperature and humidity ranges.

Compatible single-mode FC/PC patch cords should be connected to the input and output. Every connector should be inspected and cleaned before mating.

The input source should operate within the documented C-band or L-band wavelength range. Source power should be measured before connection and should remain appropriate for the required amplifier measurement.

The amplifier should be allowed to stabilize before precision measurements are recorded. Input power, output power, gain, wavelength, and optical spectrum should be monitored using suitable calibrated instruments.

The output may exceed the safe input level of sensitive test equipment. A compatible optical attenuator should be used when required.

Laser Safety

The OAB1564 is a Class 3B laser product. Invisible optical radiation may be present at the output connector, open patch cords, adapters, and fiber ends.

Users should not look into the optical output or view the signal with optical instruments unless suitable controls confirm that the source is disabled and the path is safe.

The optical output should be disabled before connectors are inspected, cleaned, attached, or removed. Appropriate laser-safety procedures, protective equipment, warning labels, access controls, and system interlocks should be used for the complete setup.

Comprehensive Functional and Performance Testing

The JDSU OAB1564+20FP0 receives comprehensive functional and performance testing before shipment. Evaluation may include AC power operation, startup, LCD response, front-panel controls, current-control operation, input and output monitor functions, optical amplification, and RS-232 communication.

Optical testing may include continuity, input and output power measurement, gain verification, saturated output evaluation, operation at representative C-band and L-band wavelengths, noise assessment, and spectral inspection using compatible test equipment.

The FC/PC optical connectors, alignment sleeves, connector threads, protective caps, controls, display, communication port, power inlet, cooling openings, enclosure, safety labels, model label, and option markings may be inspected for contamination, damage, or excessive wear.

The exact testing scope depends on available C-band and L-band optical sources, calibrated optical power meters, variable attenuators, optical spectrum analyzers, FC/PC patch cords, communication accessories, and requested test points.
