Regulatory Information

USA Electromagnetic Interference Regulatory Statement

Electronic test and measurement equipment is exempt from FCC part 15, subpart B

compliance in the United States of America. However, EXFO Inc. makes reasonable efforts

to ensure compliance to the applicable standards.

The limits set by these standards are designed to provide reasonable protection against

harmful interference when the equipment is operated in a commercial environment. This

equipment generates, uses, and can radiate radio frequency energy and, if not installed and

used in accordance with the user documentation, may cause harmful interference to radio

communications. Operation of this equipment in a residential area is likely to cause

harmful interference in which case the user will be required to correct the interference at

his own expense.

Modifications not expressly approved by the manufacturer could void the user’s authority to

operate the equipment.

Canada Electromagnetic Interference Regulatory Statement

This equipment generates, uses, and can radiate radio frequency energy and, if not

installed and used in accordance with the instruction manual, may cause harmful

interference to radio communications. Operation of this equipment in a residential area is

likely to cause harmful interference.

Cet équipement génère, utilise et peut émettre de l'énergie radio-fréquence et, s'il n'est pas

installé et utilisé conformément à la documentation de l'utilisateur, il peut occasionner une

interférence néfaste aux communications radio. L'utilisation de cet équipement dans une

zone résidentielle est susceptible d'occasionner une interférence néfaste.

Caution: This equipment is not intended for use in residential environments and may not

provide adequate protection to radio reception in such environments.

Attention: Cet appareil n'est pas destiné à être utilisé dans des environnements résidentiels

et peut ne pas assurer la protection adéquate à la réception radioélectrique dans ce type

d'environnements.

This is a class A, group 1 product.

³Class A equipment: Equipment that is, by virtue of its characteristics, highly unlikely to

be used in a residential environment, including a home business shall be classified as

class A and shall comply with the class A limits specified in the applicable ICES

standard. Characteristics considered in this assessment include price, marketing and

advertising methodology, the degree to which the functional design inhibits

applications suitable to residential environments, or any combination of features that

would effectively preclude the use of such equipment in a residential environment.

Classe A: Matériel qui, en raison de ses caractéristiques, ne sera fort probablement pas

utilisé dans un milieu domiciliaire ni par des entreprises établies à domicile. Parmi les

caractéristiques considérées dans cette évaluation, il y a le prix, les méthodes de

commercialisation et de publicité, la mesure dans laquelle les fonctions de l'appareil

font qu'il ne se prête pas à des applications convenant au milieu domiciliaire ou toute

combinaison de ces caractéristiques qui aurait pour conséquence d'en prévenir

effectivement l'utilisation à domicile. Utilisé également pour indiquer les limites

d'émission correspondantes qui s'appliquent à un tel matériel.

³Group 1 equipment: group 1 contains all equipment which is not classified as group 2

equipment, and includes equipment such as laboratory and scientific equipment,

industrial process, measurement and control equipment.

Group 2 equipment: group 2 contains all ISM RF equipment in which radio-frequency

energy in the frequency range 9 kHz to 400 GHz is intentionally generated and used or

only used locally, in the form of electromagnetic radiation, inductive and/or capacitive

coupling, for the treatment of material for inspection/analysis purposes, or for transfer

of electromagnetic energy.

Appareils du groupe 1 : le groupe 1 réunit tous les appareils compris dans le domaine

d’application de la présente Norme, qui ne sont pas classés comme étant des appareils

du groupe 2. Le groupe 1 inclut les appareils scientifiques et de laboratoire, les

processus industriels, appareils de mesure ou de contrôle.

Appareils du groupe 2 : le groupe 2 réunit tous les appareils ISM à fréquences

radioélectriques dans lesquels de l’énergie à fréquences radioélectriques dans la plage

de fréquences comprises entre 9 kHz et 400 GHz est produite et utilisée volontairement

ou uniquement utilisée localement sous forme de rayonnement électromagnétique, de

couplage inductif et/ou capacitif, pour le traitement de la matière, à des fins d’examen

ou d’analyse ou pour le transfert d’énergie électromagnétique.

Optical Tunable Filter 1

1 Introducing the XTA-50

The XTA-50 is a flat-top tunable filter for fiber-optic component and system testing. It is

designed for closely-spaced channel selection and extraction in DWDM applications.

When an optical signal is detected at the XTA-50 input port, the input wave is directed

towards the output port after passing through the XTA-50 monochromator, which is tuned at

the center wavelength via the XTA-50 software.

Each XTA-50 provides on-board touchscreen controls and user interface to drive both

system common controls and parameters. All system operations are software-controlled

from the XTA-50 user interface.

The XTA-50 system may also be remote-operated via an external screen or standard USB-B

or Ethernet interfaces.

Technical Specifications

The following table lists the technical specifications of all XTA-50 models.

Optical Specifications

All specifications are given at 21°± 3°C after 30 minutes warm-up.

XTA-50 Overview

The XTA-50 is delivered with the following accessories:

³A power supply cord

³The calibration certificate and the test report

³A USB key containing the available drivers and user documentation

Cables for fiber-optic input/output are not provided.

Front Panel

Touch Screen

The touch screen enables you to perform all possible operations on the XTA-50.

To select a parameter, command or function on the screen, touch the corresponding

command with the tip of your finger or a touch screen stylus device.

If you apply simultaneous pressure with two or more fingers, the touchscreen will not

function properly.

Optical Connectors

The two following optical connectors, protected by a dust cap, are located on the front

panel:

³IN: channel filter input port.

³OUT: channel filter output port.

The two optical connectors are mounted on a drawer, which enables you to access the

internal optical connectors for cleaning (see Cleaning Optical Connectors on page 53).
