Revision 1.2

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 7707CVTA series DWDM cards and any 7707CVRA series cards

directly with a short fiber optic cable. The 7707CVTA series DWDM card produces

+7dBm of power which will damage the receiver if connected directly.

Do not hook up the 7707CVTA series cards that output more than -7dBm of power

(see 7707CVTA series specifications for output power of various laser types) and

7707CVRA series high sensitivity (-H versions) receiver cards directly with a short

fiber optic cable. The 7707CVTA series cards that produce more than -7dBm of

power will damage the receiver if connected directly.

Revision 1.2 7707CVTA-1

1. OVERVIEW

The 7707CVTA is a VistaLINK®enabled, composite analog video and analog audio fiber transmitter for

broadcast quality video and audio signals. This single card module accepts one NTSC or PAL analog

video input with up to four analog audio inputs, performs analog to digital conversion and transmits them

over a single fiber. The companion 7707CVRA Composite Video and Analog Audio fiber receiver

demultiplexes the signals and converts them back to analog form.

The 7707CVTA-2 Dual Composite Video and Analog Audio fiber transmitter is a dual channel version that

digitizes and multiplexes 2 analog video and up to four analog audio signals and converts them to an

optical signal for transmission. The companion 7707CVRA-2 Dual Composite Video and Analog Audio

fiber receiver 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 fiber output is available in an assortment of optical wavelengths, accommodating standard or CWDM

transmission schemes. (7707CVTA shown, 7707CVTA-2 similar)

7707CVTA13 1310 nm FP -7dBm output, suitable for distances up to 50 Km

7707CVTA13M 1310 nm FP 0dBm output, suitable for distances up to 75 Km

7707CVTA15 1550 nm DFB 0dBm output, suitable for distances up to 75 Km

There are several versions with built in isolators specifically suited to coarse wave division multiplexing

(CWDM) applications. These versions all have 0dBm output and are suitable for distances up to 75 Km.

2. INSTALLATION

The 7707CVTA 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 section

3 of the 7700FR chapter.

VIDEO IN: Input BNC accepts analog NTSC or PAL video signals. On the 7707CVTA-2 there are

separate video inputs for each of the video signals. This input provides equalization

compensation for up to approximately 250m of industry standard Belden 1694 coaxial

cable.

VIDEO OUT: (7707CVTA only) Output BNC connector for additional signal distribution or signal

monitoring.

Revision 1.2 7707CVTA-5

OPTICAL OUTPUT: Output SC/PC, ST/PC or FC/PC female connector. This output contains the Time

Domain Multiplex (TDM) of the digitized analog video signal and analog audio signal.

This optical output is available in 1310nm, 1550nm, up to sixteen CWDM wavelengths

(ITU-T G.694.2 compliant) and up to 40 DWDM wavelengths (ITU-T G.694.1 compliant). The

output wavelength is marked on the rear panel of each module. When connected directly to a

companion module, the output is compatible with multi-mode fiber optic cable. If not connected

directly (i.e. connected through CWDM, DWDM, WDM, or splitter/combiner) the output is

compatible only with single-mode fiber optic cable.

Do not hook up the 7707CVTA series DWDM cards and any 7707CVRA series cards

directly with a short fiber optic cable. The 7707CVTA series DWDM cards produce

+7dBm of power which will damage the receiver if connected directly.

Do not hook up the 7707CVTA series cards that output more than -7dBm of power

(see 7707CVTA series specifications for output power of various laser types) and

7707CVRA series high sensitivity (-H versions) receiver cards directly with a short

fiber optic cable. The 7707CVTA series cards that produce more than -7dBm of

power will damage the receiver if connected directly.

AUDIO IN:Balanced analog audio inputs for 4 channels. Each input (+, -, GND) is on three of twelve pins

on a twelve pin terminal header.

product to place the label it is reproduced here in the manuals.

•There is no date of manufacture on this label as it can be traced by bar code label placed on the

Printed circuit board of each Evertz plug-in module

•The Model number is one of: 7707CVTA13, 7707CVTA13-2, 7707CVTA13M, 7707CVTA13M-2,

2.1.4. Handling and Connecting Fibers

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 section of this manual binder.
