WARNING
Never look directly into an optical fiber. Non-reversible damage to the eye can
occur in a matter of milliseconds.
"
Do not hook up the 7707CVT series DWDM cards and any 7707CVR series cards
directly with a short fiber optic cable. The 7707CVT series DWDM card
produces +7dBm of power which will damage the receiver if connected directly.
"
Do not hook up the 7707CVT series cards that output more than -7dBm of power
(see 7707CVT series specifications for output power of various laser types) and
7707CVR series high sensitivity (-H versions) receiver cards directly with a
short fiber optic cable. The 7707CVT series cards that produce more than -
7dBm of power will damage the receiver if connected directly.

7707CVR Composite Video and Analog Audio Fiber Receiver
1. OVERVIEW
The 7707CVR is a VistaLINKTM enabled, composite analog video and analog audio fiber receiver for
broadcast video quality signals. This single card module accepts a fiber optic input, demultiplexes the
signals, performs D to A conversion and outputs NTSC or PAL analog video and up to four balanced
analog audio signals. The companion 7707CVT Composite Video and Analog Audio fiber transmitter
digitizes and multiplexes the analog video and up to four analog audio signals and converts them to an
optical signal for transmission.
The 7707CVR-2 Dual Composite Video and Analog Audio fiber receiver is a dual channel version that
accepts a fiber optic input, demultiplexes the signals, performs D to A conversion and outputs 2 NTSC or
PAL analog video signals and up to four balanced analog audio signals. The companion 7707CVT-2 Dual
Composite Video and Analog Audio fiber transmitter digitizes and multiplexes 2 analog video and up to
four analog audio signals and converts them to an optical signal for transmission.
The 7707CVR-2-WAV2 fiber receiver accepts a fiber optic input and delivers one video output (CH1) and
one complete AUDIO OUTPUT (CH2) and up to 6 balanced analog audio signals. The companion
7707CVT-2-WAV2 transmitter digitizes one Video (CH1) and one complex audio (CH2) and up to 6 analog
audio signals and converts them to an optical signal for transmission.
The 7707CVR and 7707CVR-2 occupy one card slot and can be housed in either a 1RU frame, which will
hold up to three modules, or a 3 RU frame, which will hold up to 15 modules.
Features:
• Single card fiber demultiplexer for analog video and audio signals
• Supports both NTSC and PAL video signals
• Broadcast quality analog video and audio performance
• Adjustable gain and DC offset, and pre-emphasis for up to 300m of Belden 1694 coaxial cable
• Minimal Audio to Video latency
• Comprehensive signal and status monitoring via four-digit card-edge display, or through SNMP and
VistaLINKTM enabled capability
• Fully Hot-swappable from front of frame with no fiber disconnect/reconnect required
• Supports Single mode (8-10 µm) and Multi-mode (50/62.5 µm) fiber optic cable
• Accepts any wavelength in the 1270nm to 1610nm range

2. INSTALLATION
The 7707CVR comes with a companion rear plate that has two BNC connectors, one twelve pin terminal
header with removable terminal block and one SC/PC, SC/PC with cover flap, ST/PC or FC/PC optical
connector. For information on mounting the rear plate and inserting the module into the frame see the
7700FR chapter section 3.
Figure 4: 7707CVR Rear Panels
OPTICAL INPUT SC/PC, SC/PC with cover flap, ST/PC or FC/PC female connector. This wide range
input accepts optical wavelengths of 1310nm accommodating standard or 1270nm to 1610nm
CWDM transmission schemes.
"
Do not hook up the 7707CVT series DWDM cards and any 7707CVR series cards
directly with a short fiber optic cable. The 7707CVT series DWDM card
produces +7dBm of power which will damage the receiver if connected directly.

"
Do not hook up the 7707CVT series cards that output more than -7dBm of power
(see 7707CVT series specifications for output power of various laser types) and
7707CVR series high sensitivity (-H versions) receiver cards directly with a
short fiber optic cable. The 7707CVT series cards that produce more than -
7dBm of power will damage the receiver if connected directly.
ANALOG VIDEO OUTPUTS On the 7707CVR there are two composite analog video outputs. On the
7707CVR-2 there is one output for each video channel. Each output can have cable pre-
emphasis applied independently. (See section 5.3.3 for information on setting the desired pre-
emphasis)
WAUDIO Complex audio output
ANALOG AUDIO OUT Balanced analog audio outputs for 4 channels. Each output (+, -, GND) is
on three of twelve pins on the twelve pin terminal header.
2.1. CARE AND HANDLING OF OPTICAL FIBER
"
Never touch the end face of an optical fiber. Always keep dust caps on optical fiber
connectors when not connected and always remember to properly clean the optical
end face of a connector before making a connection.
The transmission characteristics of the fiber are dependent on the shape of the optical core and therefore
care must be taken to prevent fiber damage due to heavy objects or abrupt fiber bending. Evertz
recommends that you maintain a minimum bending radius of 5 cm to avoid fiber-bending loss that will
decrease the maximum attainable distance of the fiber cable. The Evertz fiber optic modules come with
cable lockout devices, to prevent the user from damaging the fiber by installing a module into a slot in the
frame that does not have a suitable I/O module. For further information about care and handling of fiber
optic cable see section 3 of the Fiber Optics System Design chapter in the front of the binder.
