JDS FITEL HA9-Z064 100 dB 62.5/125 µm Multimode Variable Optical Attenuator

JDS FITEL HA9-Z064 62.5/125 µm Multimode Variable Optical Attenuator

The JDS FITEL HA9-Z064 is a programmable variable optical attenuator configured for 62.5/125 µm multimode fiber. It is designed for precise optical signal-level control in laboratory, telecommunications, manufacturing, calibration, and automated test environments.

The attenuator provides an optical attenuation range from 0 dB to 100 dB across wavelengths from 1200 nm to 1700 nm. Attenuation can be adjusted with 0.01 dB settability at 1300 nm, supporting controlled optical power changes for receiver sensitivity testing, link-loss simulation, component characterization, and instrument verification.

A built-in optical on/off switch provides more than 110 dB of isolation and operates in less than 20 ms. This shutter allows the optical signal to be interrupted without changing the programmed attenuation setting or disabling the connected source.

The HA9-Z064 designation identifies a factory-configured instrument. The supplied product information establishes a 62.5/125 µm multimode fiber configuration. The exact connector type, front-panel port arrangement, backreflection configuration, and installed splitter or switch options should be verified directly from the individual unit.

0 dB to 100 dB Optical Attenuation

The JDS FITEL HA9-Z064 provides adjustable attenuation from 0 dB to 100 dB. This range allows the instrument to simulate both low-loss and high-loss optical paths without requiring repeated replacement of fixed attenuators.

Low attenuation settings are useful for making controlled adjustments to a strong optical signal. Higher settings support receiver sensitivity measurements, weak-signal simulation, detector testing, and system loss-budget evaluation.

The instrument changes from 0 dB to 100 dB in 2.5 seconds or less. This response supports optical-level sweeps and automated measurements requiring multiple attenuation points.

62.5/125 µm Multimode Fiber Configuration

The HA9-Z064 is configured for 62.5/125 µm multimode fiber. Compatible multimode patch cords and devices should be used throughout the optical path to preserve the intended launch conditions.

Multimode measurements can be affected by numerical aperture, connector alignment, modal distribution, source launch conditions, fiber bends, patch-cord routing, and detector geometry. Reference fibers and connection conditions should remain consistent during comparative measurements.

Single-mode patch cords should not be substituted when the test procedure requires controlled 62.5/125 µm multimode performance.

Attenuation Accuracy and Repeatability

Within the documented wavelength regions from 1280 nm to 1340 nm and from 1470 nm to 1550 nm, attenuation accuracy is specified at ±0.1 dB or ±0.004 dB per decibel of attenuation, whichever is greater.

Attenuation repeatability is specified at ±0.015 dB under constant temperature and wavelength conditions. This repeatability supports automated receiver testing, production screening, component qualification, and measurements that revisit the same attenuation settings.

Complete measurement uncertainty also depends on source stability, operating wavelength, multimode launch conditions, connector cleanliness, patch-cord condition, and the optical power meter used to verify the output.

Multimode Insertion Loss

Insertion loss depends on the numerical aperture of the multimode fiber configuration. The documented maximum insertion loss is 2.2 dB for multimode fiber with a numerical aperture of 0.2 and 2.9 dB for multimode fiber with a numerical aperture of 0.3.

These values exclude external connector loss and the additional losses of any optional switch or coupler installed in the optical path.

The specific numerical aperture of the HA9-Z064 should be confirmed when insertion-loss requirements are critical.

Built-In Optical Shutter

The HA9 incorporates a built-in optical on/off switch with more than 110 dB of isolation. The shutter interrupts the optical path without changing the programmed attenuation value.

The documented switching time is below 20 ms. This function supports dark measurements, receiver protection, automated measurement sequences, and rapid transitions between optical signal and no-signal conditions.

The shutter should not replace normal optical safety procedures. The connected source should still be disabled before connectors are inspected, cleaned, installed, or removed.

Optional Optical Configurations

The HA9 platform was available with several optional optical configurations. These included a 1 x 2 optical switch, a 50/50 optical splitter, and a 10/90 optical splitter.

If a 1 x 2 optical switch is installed, the instrument can select between two optical inputs or outputs. The HA9 documentation notes that the auxiliary 5 V output is not externally available when this switch is installed.

Optional splitter or switch functions should only be included in the final product configuration when the applicable hardware is physically present and verified.

Measurement Setup

The JDS FITEL HA9-Z064 should be installed on a stable laboratory bench or in a suitable equipment rack with adequate clearance for ventilation, optical cables, communication cables, and AC power.

Compatible 62.5/125 µm multimode patch cords should be connected to the optical input and output. The connector family and ferrule polish must match the interfaces installed on the instrument.

All optical connectors should be inspected and cleaned before mating. A sensitive receiver or detector should initially be connected with the attenuator set to a high attenuation value.

The attenuation can then be reduced gradually while optical power and device response are monitored. The source wavelength should remain within the 1200 nm to 1700 nm operating range, and input power must remain below the documented 200 mW limit.

Comprehensive Functional and Performance Testing

The JDS FITEL HA9-Z064 receives comprehensive functional and performance testing before shipment. Evaluation may include AC power operation, startup, front-panel controls, display response, attenuation adjustment, optical shutter operation, and applicable remote-control functions.

Optical testing may include input-to-output continuity, insertion loss, representative attenuation values, attenuation repeatability, attenuation range, response time, and optical shutter isolation using compatible multimode sources and calibrated optical power meters.

The optical interfaces, pigtails or bulkheads, connectors, shutter, controls, display, communication ports, AC inlet, enclosure, labels, and installed options may be inspected for contamination, damage, corrosion, or excessive wear.

The exact testing scope depends on the verified connector type, port arrangement, numerical aperture, installed options, available multimode sources, reference patch cords, power meters, and requested wavelength and attenuation points.
