7705EO-HD SMPTE292M Re-Clocking Electrical to Fiber Converter
1. OVERVIEW
The 7705EO-HD Electrical to fiber converter provides an economical method of connecting in-plant
coaxial distribution and longer distance optical distribution for SMPTE 292M (1.5 Gb/s) HDTV serial digital
signals. The companion 7705OE-HD Fiber to Electrical converter facilitates conversion back to coaxial
distribution at the destination. The 7705EO-HD converter features one auto-equalized coaxial input with
two reclocked serial digital outputs and one reclocked fiber output. The 7705EO-HD has been designed to
be used primarily as a reclocking 1.5Gb/s distribution amplifier and converter, however, it can also be
used as a non-reclocking SMPTE 310M (19.4 Mb/s), DVB-ASI or SMPTE 259M(143 to 540 Mb/s)
distribution product.
The 7705EO-HD is available in different versions to meet a variety of applications. (See specifications for
complete information)

2. INSTALLATION
The 7705EO-HD comes with a companion rear plate that has three BNC connectors and one SC/PC
(shown), 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 2: 7705EO-HD Rear Panel
HD INPUT Input BNC connector for 10-bit serial digital video signals compatible with the SMPTE 292M
standard. The 7705EO-HD can also be used in non-reclock mode with SMPTE 310M
(19.4 Mb/s), SMPTE 259M (143 to 540 Mb/s) or DVB-ASI, or most other signals with bit rate
less than 1.5 Gb/s. See section 5.1 for information on operating the module in non-reclock
mode.
HD OUTPUT There are two BNC connectors with reclocked serial component video outputs, compatible
with the SMPTE 292M standard. In non-reclock mode these outputs contain an equalized copy
of the input signal.
There is one SC/PC (shown) ST/PC or FC/PC female connector with reclocked serial
component video outputs, compatible with the SMPTE 292M standard. This connector is the
optical output from the 7705EO-HD as shown in section 3.3.

CLASS 1 LASER PRODUCT
Background colour: yellow
Triangular band: black
Symbol: black
2.1.2. Assembly
Assembly or repair of the laser sub-module is done only at Evertz facility and performed only by qualified
Evertz technical personnel.

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.

7705EO-HD SMPTE292M Re-Clocking Electrical to Fiber Converter
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.

5.1. SELECTING RECLOCK OR NON-RECLOCK MODE
There are two jumpers J8 and J9 that determine whether the module will operate as a reclocking
distribution amplifier with SMPTE 292M (1.5 Gb/s) video signals or as a non-reclocking distribution
amplifier with other data rates.
For the A and B revision of the board:
HD / BYPASS To select the normal reclocking mode remove both of these jumpers. For convenience you
may re-install the jumper so that only one side is connected.
To select the non-reclocking mode install both of these jumpers.
For the C revision and later of the board:
RCLK/NON-RCLK To select the normal reclocking mode put both of these jumpers in the RCLK
position. To select the non-reclocking mode install both of these jumpers in the NON-RCLK
position.

7705EO-HD SMPTE292M Re-Clocking Electrical to Fiber Converter
5.2. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper located at the front of the module determines whether local faults (as shown
by the Local Fault indicator) will be connected to the 7700FR frame's global status bus.
FRAME STATUS To monitor faults on this module with the frame status indicators (on the PS FRAME
STATUS LED's and on the Frame's Fault Tally output) install this jumper in the On position.
On Rev A and B boards install the jumper. (default)
When this jumper is installed in the Off position local faults on this module will not be
monitored. On rev Rev A and B boards remove the jumper and re-install it so that only one
side is connected.
5.3. SETTING THE EQUALIZER WARNING THRESHOLD
The EQ trimpot R28 located near jumper J8 is used to set the threshold of the cable equalizer warning.
The equalizer warning is factory set to 125 meters of Belden 1684 cable, but may be adjusted for other
cable types or cable lengths. To adjust the cable equalizer warning threshold, connect a signal to the
input of the DA using the required length of cable. Adjust the trimpot slowly until the Equalizer warning
LED comes on. You can verify that the equalizer warning is operating correctly by removing a few meters
of cable from the input. The LED should go off.
