Important Safety Instructions
Read and follow all warning notices and instructions marked on the product
and included in the manual.
Veuillez lire et respecter toutes les notices d'avertissement et les instructions
indiquées sur le produit et inclues dans le manuel.
Laser Safety Instructions
Zhone equipment and associated optical test sets use laser sources that emit
light energy into fiber cables. This energy is within the red (visible) and
infrared (invisible) regions of the electromagnetic spectrum.
Laser products are subject to federal and state or provincial regulations, and
local practices. Regulation 21 CFR 1040 of the U.S. Bureau of Radiological
Health requires manufacturers to certify each laser product as Class I, II, III,
or IV, depending upon the characteristics of the laser radiation emitted. In
terms of health and safety, Class I products present the least hazard (none at
all), while Class IV products present the greatest hazard.
Although Zhone optical products have a Class I certification, hazardous
exposure to laser radiation can occur when fibers connecting system
components are disconnected or broken.
Certain procedures carried out during testing require the handling of optical
fibers without dust caps and therefore increase the risk of exposure. Exposure
to either visible or invisible laser light can damage your eyes under certain
conditions.
Read and observe the following precautions to decrease the risk of exposure
to laser radiation.
WARNING! Risk of eye damage. At all times, when handling
optical fibers, follow the safety procedures recommended by your
company.
WARNING! Avoid direct exposure to fiber ends or optical
connector ends. Laser radiation may be present and can damage
your eyes.
WARNING! Never look into an active optical fiber or an optical
fiber connector opening of an active or powered-up unit.
Note: When working with optical fibers, take these precautions:
•Wear safety glasses when installing optical fibers.
•Clean hands after handling optical fibers. Small pieces of glass are not
always visible and can cause eye damage. Get medical assistance
immediately for any glass that comes into eye contact.
Important Safety Instructions
zNID 27xx Series Hardware Installation Guide 13
•Prevent direct exposure to optical fiber ends or optical connector ends
where laser signals are directly accessed. Do not handle pieces of optical
fiber with fingers. Use tweezers or adhesive tape to lift and discard any
loose optical fiber ends.
•Wear rubber gloves to clean optical connectors. The gloves prevent direct
contact with the isopropyl alcohol and prevent contamination of the
ferrules with skin oils.
•Place all optical fiber clippings in a plastic container provided for that purpose.
•Handle optical fibers with caution. Place the optical fibers in a safe
location during installation.
•Follow the manufacturer instructions when using an optical test set. Incorrect
calibration or control settings can create hazardous levels of radiation.
Instructions de sécurité relatives au laser
Le matériel de Zhone et les ensembles de tests optiques associés utilisent des
sources de laser qui émettent de l'énergie lumineuse dans les câbles optiques.
Cette énergie se situe entre les régions rouge (visible) et infrarouge (invisible)
du spectre électromagnétique.
Les produits laser sont sujets à des réglementations fédérales et étatiques ou
provinciales, ainsi que des pratiques locales. La Réglementation 21 CFR 1040
du U.S. Bureau of Radiological Health oblige les fabricants à certifier chaque
produit laser selon les Classes I, II, III, ou IV, en fonction des caractéristiques
de la radiation laser émise. En termes de santé et de sécurité, les produits de
Classe I présentent le moins de danger (aucun), alors que les produits de
Classe IV présentent les plus grands dangers.
Bien que les produits optiques de Zhone disposent d'une certification de
Classe I, une exposition dangereuse aux radiations laser peut se produire
lorsque les composants du système de connexion des fibres sont déconnectés
ou cassés.
Certaines procédures réalisées lors des essais nécessitent la manipulation de
fibres optiques sans capuchons antipoussière et augmentent donc le risque
d'exposition. L'exposition à la lumière laser visible ou invisible peut
endommager vos yeux dans certaines conditions.
Lisez et observez les précautions suivantes pour diminuer le risque
d'exposition aux radiations laser.
WARNING! AVERTISSEMENT ! Risque de blessure aux yeux.
Lors de la manipulation de fibres optiques, suivez en permanence
les procédures de sécurité recommandées par votre société.
WARNING! AVERTISSEMENT ! Evitez l'exposition directe aux
extrémités des fibres ou aux embouts des connecteurs optiques.
Le laser pourrait vous irradier et blesser vos yeux.
About This Guide
14 zNID 27xx Series Hardware Installation Guide
WARNING! AVERTISSEMENT ! Ne regardez jamais dans une
fibre optique active ou une ouverture de connecteur de fibre
optique d'un appareil actif ou sous tension.
Remarque : Lorsque vous travaillez avec des fibres optiques, prenez ces
précautions :
•Portez les lunettes de protection lorsque vous installez des fibres optiques.
•Lavez-vous les mains après avoir manipulé des fibres optiques. De petites
pièces de verre ne sont pas toujours visibles et peuvent provoquer des
affections oculaires. Obtenez une assistance médicale immédiatement
pour tout morceau de verre entrant en contact avec les yeux.
•Evitez l'exposition directe aux extrémités des fibres optiques ou aux
extrémités des connecteurs optiques où les signaux laser sont directement
accessibles. Ne manipulez pas de parties de fibres optiques avec les
doigts. Utilisez des pinces typographiques ou du ruban adhésif pour lever
et éliminer des extrémités lâches de fibres optiques.
•Portez des gants de caoutchouc pour nettoyer les connecteurs optiques.
Les gants protègent du contact direct avec l'alcool isopropylique et évitent
la contamination des ferrules avec les huiles de peau.
•Placez toutes les rognures de fibre optique dans un récipient en plastique
fourni à cet effet.
•Manipulez les fibres optiques avec précaution. Placez les fibres optiques
dans un endroit sûr lors de l'installation.
•Suivez les instructions du fabricant lors de l'utilisation d'un ensemble de
test optique. Un étalonnage ou des paramètres de contrôle incorrects
peuvent provoquer des niveaux dangereux de radiation.

Installation precautions
Maximum operating temperature should not exceed the range of 0° C to 40° C
(32° F to 104° F).
Ensure that proper cable grades are used for all system and network
connections. For best results, use the cables and connectors recommended in
this document.
Connect the system to the power supply circuit as described in this document.
Before making fiber connections, be sure that the optical cable fiber tips and
components are clean and free of dust and debris. Follow established cleaning
procedures if required.
Note: Sharp bends in fiber cables create undesirable optical
attenuation or loss. The zNID fiber tray provides fiber spools and
hooks to avoid sharp bends in the fiber cable. A minimum bend radius
of 30 mm (1.2 in) is recommended for stripped fiber.
La température maximum de fonctionnement ne doit pas dépasser le plage de
0° C à 40° C (32° F à 140° F).
Assurez-vous que les rangs de câbles corrects sont utilisés pour tous les
raccordements du système et du réseau. Pour les meilleurs résultats, utilisez
les câbles et connecteurs recommandés dans ce document.
Raccordez le système au circuit d'alimentation comme décrit dans ce
document.
Avant de réaliser les raccordements des fibres, soyez sur que les embouts de
fibre des câbles optiques et les composants sont propres et libres de poussière
et autres débris. Suivez les procédures de nettoyage établies si nécessaire.
Note: Remarque : Les courbes serrées dans les câbles optiques
créent une atténuation ou une perte optique indésirable. Le plateau de
fibres zNID fournit des bobines et des crochets de fibre afin d'éviter
les courbes serrées dans le câble optique. Un rayon de courbure
minimum de 30 mm (1,2 po) est recommandé pour la fibre dénudée.

42 zNID 27xx Series Hardware Installation Guide
Manage the optical cable
When making a fiber optic connection, avoid touching the fiber cable ends to
the outside of the mating connector. Touching can contaminate the
connectors.
Fiber handling
Before making any connections, be sure that the optical cable fiber tips and
components are clean and free of dust and debris.
The zNID fiber tray provides fiber spools and hooks to avoid sharp bends in
the fiber cable. A minimum bend radius of 30 mm is recommended for
stripped fiber and larger fiber needs a larger bend radius to guarantee the
specified system performance.
Note: Sharp bends in fiber cables create undesirable optical
attenuation or loss.
Testing optical power
Table 6 specifies how much laser power to expect on the fiber.

Optical fiber cable placement with the zNID mounting bracket
zNID 27xx Series Hardware Installation Guide 43
Optical fiber cable placement with the zNID mounting bracket
Using a fiber tray involves routing the optical fiber around the prongs, then
physically to the SC connector in the zNID 27xx .
Note: Sharp bends in fiber cables create undesirable optical
attenuation or loss. The zNID enclosure provides fiber spools and
hooks to avoid sharp bends in the fiber cable. A minimum bend radius
of 30 mm (1.2 in) is recommended for stripped fiber.
To place the fiber cable in the fiber tray:
1Inspect and clean the fiber connector to ensure it is free of impurities.
2Make sure the fiber segment is properly installed in the fiber tray, excess
cable is wrapped around fiber reels without having improper bends
leaving enough loose cable so that it will not take too sharp of a bend to
connect to the zNID.
Figure 14: Maintain the proper bend radius in the fiber
3Test the fiber cable to verify clean signals.
Note: It is recommended that the fiber cable be tested before
finishing.
