2. INSTALLATION
The 7705OE-3 comes with a companion rear plate that has three BNC connectors and three SC/PC
(shown), ST/PC or FC/PC optical connectors. For information on mounting the rear plate and inserting the
module into the frame see section 3 of the 7700FR chapter.
Figure 2-1: 7705OE-3 Rear Panel
SDI INPUT: There are three SC/PC (shown), ST/PC or FC/PC female optical connectors for 3
separate channels of SMPTE 297M optical 10-bit serial digital video signals
compatible with the SMPTE 259M, SMPTE 305M SMPTE 344M, DVB-ASI or
SMPTE 310M (19.4 Mb/s) standards.
SDI OUTPUT: There are three BNC connectors each with a reclocked serial component video output
converted from the corresponding channel. The output signals are compatible with the
SMPTE 259M, SMPTE 305M SMPTE 344M, DVB-ASI or SMPTE 310M (19.4 Mb/s)
standards. See section 5.2 for information about operating the module with SMPTE
310M signals.

2.1. CARE AND HANDLING OF OPTICAL FIBER
2.1.1. Safety
!
Never look directly into an optical fiber. Non-reversible damage to the eye can occur
in a matter of milliseconds.
The laser modules used in the Evertz fiber optic modules are Class I, with a maximum output power of
7mW, and a wavelength of 1270 to 1610nm.
2.1.2. Handling and Connecting Fibers
"Never touch the end face of an optical fiber.
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 3 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 of this manual.

4.1. STATUS INDICATOR LEDS
Two large LEDs on the front of the board indicate the general health of the module:
LOCAL FAULT: This Red LED indicates poor module health and will be On during the absence of a
valid input signal on all 3 inputs, if any input detects a weak optical carrier, or if a local
input power fault exists (i.e.: a blown fuse). The LOCAL FAULT indication can also be
reported to the frame through the FRAME STATUS jumper.
MODULE OK: This Green LED indicates good module health. It will be On when a valid input signal is
present on at least one of the input channels and board power is good.
There are three small LEDs that indicate the status for each channel.
PRESENT: This Green LED indicates the presence of a valid input video signal.

5. JUMPERS AND LOCAL CONTROLS
5.1. SELECTING WHETHER LOCAL FAULTS WILL BE MONITORED
BY THE GLOBAL FRAME STATUS
The FRAME STATUS jumper 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 Power
Supply FRAME STATUS LED's and on the Frame's Fault Tally output) install this
jumper in the On position. (default)
When this jumper is installed in the Off position local faults on this module will not be
monitored.
5.2. SELECTING THE RECLOCKING RATE
The RATE SELECT jumpers J18, J21, and J22, determine whether the channel 1, 2 or 3 respectively will
operate as a distribution amplifier with SMPTE 259M (143 to 540 Mb/s), SMPTE 305M, SMPTE 344M or
DVB-ASI video signals or with SMPTE 310M (19.4 Mb/s) signals.
RATE SELECT: To set the module to operate with SMPTE 259M, SMPTE 305M, SMPTE 344M or
DVB-ASI signals install the jumper in the 259M position.
To set module to operate with SMPTE 310M signals install the jumper in the 310M position.
