Nano-OSA module

Figure 1.1: Nano-OSA module

The Nano-OSA is Viavi’s new generation of DWDM

analyzer modules. It scans the full C-band wavelength

range between 1260 and 1650 nm for commissioning,

upgrade, and trouble shooting of DWDM networks. The

Nano-OSA oﬀers the functionality and speed of an optical

spectrum analyzer in a handheld form at a fraction of the

price of an conventional OSA. The measurement result

is displayed in a graphical (trace) and numerical (table)

format providing detailed information of the power level

and the wavelength of DWDM channels.

Nano-OSA user manual 5/59

Introduction

SFP Slots

The Nano-OSA oﬀers 1 integrated SFP slot for mounting

one SFP transceiver module or tunable laser (to be

ordered separately). These SFP+ modules can be used

as a DWDM stimulus to check DWDM networks together

with the DWDM analyzer.

An activated transceiver module connected to the SFP+

slot emits optical radiation at the output “TX”. The

input “RX” of the transceiver module has no function.

The optical laser radiation is indicated by LEDs assigned

to the SFP slots. The SFP modules are hot pluggable

and can be changed during operation of the Nano-OSA.

2SAFETY INFORMATION

Intended and proper use

The Nano-OSA devices are meant for professional use

only.

User must meet the the user requirements to operate the

device.(see next section)

Intended use also includes reading and following all user

information available for the devices. In particular, the

safety instructions in this book and in the user manual

of the device.

This instrument is intended for measurements on optical

ﬁber devices and systems.

◮The instrument is intended for indoor usage only.

◮

Please make sure the instrument is not operated

outside the permitted ambient conditions.

◮Observe the speciﬁed measurement range.

◮

Always make sure that the instrument is in proper

working order before switching it on.

◮

The module shall only be operated in VIAVI ap-

proved mainframes.

User requirements

OSA devices must be operated by skilled and trained

people only.

Skilled and trained people are those, who successfully

completed an appropriate training for handling laser

products or have been instructed in detail in handling

these products.

Laser safety

General laser safety

Laser radiation can cause irreparable damage to

the eyes and skin.

The Nano-OSA SFP-Bay laser sources are Class 1 laser

products according to DIN EN IEC 60825-1:2014 or 60825-

1:2007. Class 1 lasers are safe under reasonably foreseeable

operating conditions, including the use of optical aids.

◮

Nevertheless, heed the normal precautions for working

with laser radiation and consider local regulations.

The laser class to be observed depends on the laser source

connected to the OSA module. This can reach up to laser

Class 4 for the high power versions. The beam as well as

reflections of a Class 4 laser can be dangerous for eyes and

skin, even without an optical instrument (magnifying glass,

microscope, binoculars) in front of the eye).

◮Always be aware of the hazard level of the device

to be connected!

To find out the appropriate laser

classification, associated wavelengths and optical power

levels, see the specifications in the operating manual of

the connected laser and follow the instructions given

there.

◮

Connect all optical fibers before switching on the radia-

tion source.

◮

Switch off the laser source before disconnecting the opti-

cal fibers.

◮

Never look directly into the output of a laser source or

into an optical fiber connected to it.

◮Do note expose skin to the beam.

◮Always cover unused ports.

◮

Heed the normal precautions for working with laser

radiation and consider local regulations.

Laser classiﬁcation of the SFP module

SFP laser classification

Laser radiation can cause irreparable damage to

eyes and skin.

Always be aware of the laser classification of the device to be

connected! To find out the appropriate laser classification,

associated wavelengths and optical power levels, see: – the

label on the SFP module – the “Specifications” chapter in

the user manual of the SFP

◮Use only class 1 laser products in the SFP slots.

◮

However, the user is free to use any other SFP

transceiver compatible with the SFP Multi Source

Agreement (MSA).

◮

In this case you must observe the laser classifica-

tion of the inserted SFP transceiver and its safety

instructions!

Safety instructions for class 1

laser products

Invisible laser radiation

Class 1 laser products are defined as safe in normal

operation mode

◮

Although the laser radiation from a class 1 laser prod-

uct will not harm eyes or skin, follow the general

laser safety instructions (see General laser safety in-

structions) to ensure maximum safety when working

with laser sources.
