SECTION 1: INTRODUCTION
BEFORE YOU BEGIN
All personnel testing optical fibers should be adequately trained in the field of fiber optics before using any fiber optic test equipment.
If the user is not completely familiar with testing fiber optics, they should seek competent training. Such training can be acquired from
a variety of sources, such as local hands-on training classes or online courses.
Optical Channel Monitors (OCM) are used to take incoming signals from Dense Wave Division Multiplexers (DWDM), and split these
signals into separate channels based on the grid of frequencies/wavelengths defined in the ITU-T Rec. G.671 standard. The output
power of each channel is measured and plotted on a graph.
DWDM systems typically use singlemode fibers as the physical medium, and singlemode lasers for transmission. As such,
technicians working with DWDM systems should follow industry standard laser safety procedures to protect their eyes from
accidental exposure to the high-intensity laser outputs of DWDM transmitters.
The OCM-C from OWL is capable of measuring 96 DWDM channels from 191.30 to 196.05 Terahertz, using 50 Gigahertz spacing.
Each of these channels are measured for optical power levels, which are compared to user-definable minimum and maximum power
levels (useful for determining PASS/FAIL). Captured data is then plotted on a bar graph on the color LCD display – each channel
shows different colors to denote whether the signal is too high, too low, or within acceptable power levels.
Users can also choose specific ranges of channels to scan, toggle views between hertz and wavelength, and choose whether to use
frequency or wavelength for channel numbering (lowest value is channel 1). Two cursors are available so users can zoom in on a
specific range of channels for closer inspection.
Scan data can be stored in permanent memory, which can be recalled on the LCD display and downloaded into our OCM software.
The color LCD display implements state-of-the-art display technology that “flips” the display between portrait or landscape mode
automatically simply by rotating the device 90°.
Powering the OCM-C is a re-chargeable Lithium-polymer battery that allows for hours of normal usage.up to 20

Eye Safety
look into the connector port of any fiber optic test or transmission equipment, patch cable, fiber link, or other
installed fiber. Always assume that active laser equipment is attached to optical fibers, and is powered on.
Electrical Safety
Only use appropriate AC adapters for charging this device. Use of inappropriate power adapters could cause damage to
the device, and could cause harm to the user from fire and electrical shock.
Operational
eep connector ferrules and optical connector ports clean to prevent irreparable damage to the test port. For best results,
replace dust caps after each use.
Connector
do NOT insert APC (Angled Physical Contact) connectors into the test port, unless the port is clearly
marked asAPC.
Service

Channel information is located below the bar graph area, and will change when the
cursors are moved to new channels.
The three columns of information are as follows:
COLUMN 1 channel number at cursor position
channel number at cursor position
COLUMN 2 wavelength/frequency of channel at cursor position
wavelength/frequency of channel at cursor position
total optical power being received from all channels
COLUMN 3 optical power of channel at cursor position
optical power of channel at cursor position
difference in channel optical power between red and
green cursor positions
NOTE: Channels with peaks are saturated (i.e. too high to be measured accurately – over -10 dBm).
The power values will change color when saturated channels are selected. When a channel includes
saturated data points, the data is no longer accurate.
When saturated data points are detected, it is suggested to use an attenuator of an appropriate value
to adjust the optical power below -10 dBm.
To compensate for the additional attenuation, add the attenuator value as Insertion Loss (see the OCM
CONFIGURATION menu for more information).

OSA CONFIGURATION
INPUT GAIN – sets the gain of the OSA receiver.
LOW normal gain
HIGH increases gain by 10 dB
AUTO device auto-adjusts the gain based
on total incoming optical power
INSERTION LOSS – sets the insertion loss in dB of the OSA
connection to the fiber under test. The default value is 0.0
dB because a direct coupled fiber should have a low
insertion loss.
However, if the connection is a tap port of a fiber splitter, or if
you are using an in-line attenuator to “pad” the signal, the
insertion loss of the tap port or attenuation value of the
attenuator should be used. This insertion loss value is
added to the measured channel power to give the actual
channel power on the fiber under test.
PEAK THRESHOLD – in LOW gain mode, this is the
minimum power in dBm that a channel must have to be
considered active. The valid range is -20.0 to -50.0 dBm.
CHANNEL SPACING – sets channel spacing to 50GHz or
100GHz according to ITU G.694.1 DWDM channel grid
CHANNEL OFFSET – selects the OCM module channel
number to be used as the first channel number based on the
user’s particular channel number system.
For example: if the frequency of the user’s channel 13 is the
same frequency as the OCM module channel 1, set the
channel offset number to 13.
See the appendix for the OCM-C channel grid.
