CVM singlemode 4 channel video modem for uni-
directional video, audio, data & contact closure
transmission, in-band management
Introduction
CVM is a common nominator for video modems (transmitter
& receiver) in the CFO OP-X platform. The CVM is a basic
building block for multi-channel video transmission system
providing unidirectional transmission of 4 video channels with
two uni-directional data, one audio and one contact closure
channels over one singlemode fibre. PAL, NTSC and SECAM
video formats are supported to provide a transparent video
transmission. It is also possible to transmit 2 S-video chan-
nels that comprises separate luminance (Y) and chrominance
(C) signals. All common data protocols are supported as well
and are easily configured by terminal software interface.
Optical transmission is based on DFB laser operation. The
multiplexed data stream of 540 Mbps enables a full quality
and a zero-delay video transmission in one singlemode fiber
over distances of tens of kilometres (over 70 km).
Management connection between CVM units and e.g. laptop
or PSION is based on a serial data communication by means
of any terminal type program.
Management software for CVM
series fibre optic link units is a Command Line Interface type
(CLI) and it is meant for configuration and controlling of CVM
link units (see page 19).
In addition to standard 1310 nm and 1550 nm outputs, the
CVM units complies to ITU G.694.2 CWDM wavelength grid
with 20 nm spacing. Available ITU CWDM channels for CVM
units are C11...C18.
All CVM units are compatible with all CFO rack systems.
Stand-alone options are available with the CMA module
adapter and a separate mains adapter.

GENERAL
The CVM is an eight channel optical transmitter
for uni-directional video transmission with two
uni-directional data, one audio and one contact
closure channel in a singlemode fibre. The
current consumption is max. 700 mA (+12V DC).
FRAME INSTALLATION
The module is to be pushed along the guide
rails into the installation frame (e.g. CSR216 or
316 series) and secured with the four locking
screws. The unit can be freely positioned in any
slot in the frame. The empty positions in the
frame should be blanked off with cover plates.
The supply voltage is to be provided by a
CPS384 power supply unit.
VIDEO INPUTS AND INDICATOR LEDS
The impedance of the video inputs (BNC
female) is 75 Ω. The nominal input level is
1 Vpp.
Each video input is equipped with the dual
colour VIDEO led on the front panel. In case a
video signal is present and in nominal level
(and the unit detects video synchronization
pulses), the VIDEO led is green. If there is no
video signal, or the video level is too low, the
VIDEO led is yellow.
The video inputs (1...4) are switched to the
Normal video or Data/S-video usage by DIP
switches on the bottom of the unit. The default
factory setting is normal video.

S-VIDEO CONNECTION
It is also possible to transmit two S-video signals that com-
prises separate luminance (Y) and chrominance (C) signals.
This, however, uses two channels per one transmission channel
as shown in picture 2 below. Connect Yand Csignals to any of
video inputs (1...4). Make sure that the Yand Cconnections are
corresponding both at transmitter and receiver.
Note! The video LEDs (1...4) on the front panel are locked
to the synch pulse transmitted in the Ychannels.
DIP SWITCHES
Normal video position is meant for normal composite video or
S-video’s luminance (Y) signal transmission.
Data/S-video position is meant when connect CSX series
multiplexer in system or when transmit s-video’s chrominance
(C) signal. The DIP switch at the bottom of unit is meant for
unit’s programming. The default factory setting is “normal”.

LINK STATUS AND MODULE INDICATOR LEDS
When the optical input signal level is adequate and in syncron-
ization to input data is achieved, the LINK STATUS led on the
front panel is green. If optical input signal level is adequate,
but no syncronization is achieved the LINK STATUS led blinks
green/yellow. If optical input signal is missing or it’s level is too
low, the the LINK STATUS led is yellow.
When the supply voltage is not in the permitted range
(10.5...14 V DC) or there is a transmitter laser failure, the
MODULE led colour on the front panel is red.
When the unit’s
temperature is not in the permitted range, the MODULE led
blinks green/red.
During normal operation MODULE led is
blinking green (blinking indicates embedded software is
working properly).

FIBRE CONNECTION
Depending on the model, the CVM unit operates either on
standard 1310 or 1550 nm wavelenghts or ITU CWDM
wavelenghts from 1471 nm (C11) to 1611 nm (C18) with 20
nm spacing.
All optical port connectors are of type SC/APC
8° female. The nominal optical output level is +3 dBm. The
optical output level is constant and cannot be adjusted.
Available optical link budget is 29 dB (see table 18).
When installing the fibre optic cable, do not exceed the mini-
mum bending radius when connecting cable to the system.
For correct optical operation ensure that:
* Protect opened connectors always with dustcaps
* Use only 8° angle polished SC/APC connectors
* Clean all connectors before mating by using metyl or
isopropyl alcocol and dry connectors by compressed air

AUDIO CONNECTION
The AUDIO connector contains one uni-directional audio
channel line (TX --> RX). The audio output impedance is
constant and cannot be adjusted. The audio output imped-
ance is 10 Ω.
The connector in use is a RJ-45 female connector (see
picture 5 and table 28 for detailed description).
The recom-
mended cable for AUDIO connection is CIC603 (RJ-45/open
wires, see table 27 for detailed description).
The AUDIO 600
led indicates the status of audio impedance and the AUDIO
OVL led indicates the status of audio level. See table 29 for
explanation of AUDIO connector’s leds.

The CCL connector
(RJ-45 female).
CCL OUT led indicates status of
CCL output signal.
In the (uni-directional) receiver
(RX) unit the CCL IN led is only
monitored by the optical transmitter
(TX). Therefore the CCL IN led in
receiver has no real value and is
always grey.
CONTACT CLOSURE LOOP (CCL) CONNECTION
The CCL connector contains one uni-directional contact
closure channel line
(TX --> RX) . The CCL input is a normal
short circuit on/off - signal between connector’s contact pins 8
and ground (pins 1, 2, 5 or 6).
The CCL output is a normal output relay (dry contact) on/off -
signal between connector’s contact pins 3 and 4.
The connector in use is a RJ-45 female connector (see
picture 13 and table 31 for detailed description) . The recom-
mended cable for CCL connection is CIC603 (RJ-45 male/
open wires, see table 30 for detailed description).
The CCL IN/OUT leds indicates the status of CCL connection.
See table 32 for explanation of CCL connector’s leds.
The CCL output channel can be alternatively configured for
VSA usage by using a PC and any terminal type communi-
cation software (see page 19) . The default factory setting is
CCL usage (CC1=CC1).

LINK STATUS AND MODULE INDICATOR LEDS
When the optical input signal level is adequate and in syncron-
ization to input data is achieved, the LINK STATUS led on the
front panel is green. If optical input signal level is adequate,
but no syncronization is achieved the LINK STATUS led blinks
green/yellow. If optical input signal is missing or it’s level is too
low, the the LINK STATUS led is yellow.
When the supply voltage is not in the permitted range
(10.5...14 V DC) or there is a transmitter laser failure, the
MODULE led colour on the front panel is red. During normal
operation MODULE led is blinking green (blinking indicates
embedded software is working properly).
ALARM CONNECTIONS
All alarms at the rear connector of the unit are low open
collector outputs, with the capability of 30 V/10 mA
switching.
Table 33.
Open collector alarms.
Note! At the rear of unit is located a DIP switch for factory
use only (see example picture below). If this switch is set
to “Program” (lower position), the unit goes to “program-
ming state” and then has no normal operation. Default fac-
tory setting is “Normal” (lower position).

VIDEO SOURCE ALARM (VSA)
The CCL output channel can be alternatively configured for
VSA usage. In receiver units the VSA is only monitored by the
transmitter’s video input. When VSA mode is enabled and
transmitter’s video input is missing
(link otherwise operates
normally, but e.g. only the camera is broken) , the CCL OUT
led blinks yellow and CCL output pins are closed. The VSA
function can be set on/off by using a PC and any terminal type
communication software (see page 19). The default factory
setting is CCL usage (CC1=CC1).
See table 35 for explanation of CCL connector’s OUT led
when VSA function is set active.
Note! Video detection has 20 sec delay before VIDEO
SOURCE ALARM is activated / inactivated.

FIBRE CONNECTION
Depending on the model, the CVM unit operates either on
standard 1310 or 1550 nm wavelenghts or ITU CWDM
wavelenghts from 1471 nm (C11) to 1611 nm (C18) with 20
nm spacing.
All optical port connectors are of type SC/APC
8° female. The nominal optical input level is -1 dBm. Available
optical link budget is 29 dB (see table 36).
When installing the fibre optic cable, do not exceed the mini-
mum bending radius when connecting cable to the system.
For correct optical operation ensure that:
* Protect opened connectors always with dustcaps
* Use only 8° angle polished SC/APC connectors
* Clean all connectors before mating by using metyl or
isopropyl alcocol and dry connectors by compressed air
