1.5 General Safety
1.5.1 Cautions and Warnings
Disconnect all power from electronic devices before servicing. Some equipment may have
multiple power cords requiring disconnection.
1.5.2 Laser Safety
WARNING: Fiber optic equipment may emit laser or infrared light that can injure your
eyes. Never look into an optical fiber or connector port. Always assume that fiber optic
cables are connected to a laser light source.
CAUTION: Do not install or terminate fibers when a laser may be active.
WARNING: Never look directly into a live optical fiber. Always wear appropriate laser
safety glasses when working with open fiber cables that might be connected to an
operational laser transmitter. Direct open fibers ends away from faces.
CAUTION: Use of controls or adjustments or performing procedures other than those
specified herein may result in hazardous radiation exposure.
If a fiber optic laser device output is recognized as a higher than Class 1 product (Class 1M, for
example), the device is evaluated, labeled, and certified by TUV. Class 1 and 1M outputs are
not considered hazardous, but laser safety practices should always be observed.
A fiber optic transceiver emits either single-mode or multi-mode light into a fiber optic strand.
Take the following precautions when handling optical fibers.
• Wear safety glasses when you install optical fibers.
• Be aware of the risk of laser radiation exposure.
• Always assume that fiber optic cables are active because transmitted light is invisible to
the human eye.
• Never look directly into a beam (T
light can damage your eyes.
• Place optical fibers in a safe location during installation.
• Protect optical fiber connectors with clean dust caps for safety and sanitation.
• Follow the manufacturer instructions when using optical test equipment.

1.5.3 Laser Device Classifications
Laser devices of class 1M, class 2, class 2M and class 3R
Precautionary measures are only necessary to avoid a permanent direct looking into the laser
beam; for classes 2 and 2M is a momentary (0.25 sec.) irradiation in a wave length range
between 400 nm and 700 nm, as it may occur when you accidentally look into the beam, not
considered to be dangerous. However, you should not level the laser beam intentionally at
people. The use of optical aids (e.g. binoculars) together with laser devices of the classes 1M,
class 2M and class 3R may increase the danger for the eyes

Fiber Driver® EM316EDFA User Guide
1.5.4 Static Electricity
Eliminate static electricity in the workplace by grounding operators, equipment, and devices
including components and computer boards. Grounding prevents static charge buildup and
electrostatic potential differences. Transporting products in special electrostatic shielding
packages reduces electrical field damage potential.
1.5.5 Workplace Preparation
A safe and effective workplace provides the following items.
• ESD protective clothing/smocks: Street clothing must not come in contact with components
or computer boards since the various materials in clothing can generate high static charges.
ESD protective smocks, manufactured with conductive fibers, are recommended.
• Electrostatic shielding containers or totes: These containers (bags, boxes, etc.) are made of
specially formulated materials, which protect sensitive devices during transport and storage.
• Antistatic or dissipative carriers: These provide ESD protection during component movement
in the manufacturing process. It must be noted that antistatic materials alone will not provide
complete protection. They must be used in conjunction with other methods such as totes or
electrostatic shielding bags.
• Dissipative tablemat: The mat should provide a controlled discharge of static voltages and
must be grounded. The surface resistance is designed such that sliding a computer board or
component across its surface will not generate more than 100 V.
• Operator grounding: Keep a wrist strap or ESD cuff in constant contact with bare skin with a
cable for attaching it to the ESD ground. The wrist strap drains off the static charge of the
operator. The wrist strap cord has a current-limiting resistor for personnel safety. Wrist straps
must be tested frequently to ensure that they are undamaged and operating correctly. Use
special grounding heel straps or shoes when a wrist strap is impractical. These items are
effective only when used in conjunction with a dissipative floor.
• ESD protective floor or mat: The mat must be grounded through a current-limiting resistor.
The floor or mat dissipates the static charge of personnel approaching the workbench.
Special conductive tile or floor treatment can be used when mats are not practical or cause a
safety hazard. Chairs should be conductive or grounded to the floor with a drag chain.

2 Introduction to EM316EDFA Optical Amplifiers
The fiber optic amplifier module is used to increase an optical signal for extended range or clarity
without electrical conversion circuitry. The MRV EM316EDFA modules boost an optical input up to 20
decibels. The amplifier also has a bandwidth of 40 nm, making it suitable for use in wavelength
division multiplexing (WDM) applications as an optical spectral amplifier. The module may be
controlled from the network through the MRV EM316LNXNM-OT Network Manager Module.
Optical amplifiers operate in different modes, depending upon their position in the optical link. The
EM316EDFA is available in two configurations to fill the necessary roles in your network.
EM316EDFA-BR
EM316EDFA-LPR
The example below illustrates how the EM316EDFA optical amplifiers fit into an optical link.

EM316EDFA-BR is used as long haul booster module in combination with an EM316EDFA-LPR inline
pre-amplifier.

2.1 Features
The EM316EDFA board can run in standalone mode without any input from a management
module. The EM316EDFA analog input power determines the output power because the module
runs at a fixed gain.
EM316EDFA status is reported through SNMP through a network management module as well as
by LEDs on the front panel.
The green “SD” LED on the front panel indicates input greater than the thresholds corresponding to
the EDFA module type, as indicated in the table below.
EM316EDFA-BR -8 dBm
EM316EDFA-LPR -30 dBm
A green LED at front panel (Optical Output) indicates output power greater than -10 dBm.
The module temperature is measured from 0
against excessive heat, the laser shuts down when measured temperature reaches 70

3.5 Module Installation
EM316xx cards are hot-swappable in a powered Fiber Driver chassis. Install the EM316xx module
by aligning the edge of the card with the rail of the chassis slot. Hand-tighten the thumb screw. Do
not over-tighten.
The thumb screw is on the left when installed in the BU-1, BU-2, BU-3, and BU-4 chassis. The
thumb screw is on the bottom when installed in the BU-16 chassis.
3.5.1.1.1 Tools
• 6-inch Phillips #1 screwdriver (for some module screws)
• 6-inch flat-tip 5.0 screwdriver
3.5.1.1.2 Procedure
Follow all guidelines to eliminate static electricity while handling the module and other electronic
devices. Refer to the front of this manual for some safety suggestions.
Step 1 Remove the blank panel or old module from the target chassis slot. Unfasten the
mounting screws with a 6-inch Phillips screwdriver, or disengage any thumb screws by hand.
Figure 4 -- Remove the required blank panels
To comply with FCC regulations and for optimal cooling air flow, a cover panel or a module must
cover every chassis slot. To limit external signals, no chassis slot should remain open when the
unit is operational. Secure modules and panels with appropriate screws for grounding and
further compliance.
