7705OE-HD HDTV Optical to Electrical Converter, 19.4Mb/s to 1.5Gb/s

Revision 1.6 7705OE-HD - 1

1. OVERVIEW

The 7705OE-HD Fiber to Electrical converter provides an economical method of converting incoming

optical distribution for SMPTE 292M (1.5 Gb/s) HDTV serial digital signals to in-plant coaxial distribution.

The companion 7705EO-HD Electrical to Fiber converter facilitates conversion from coaxial distribution at

the source. The converter features one optical input with three re-clocked serial digital outputs. The

7705OE-HD has been designed to be used primarily as a reclocking 1.5Gb/s distribution amplifier,

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 7705OE-HD is available in 2 different versions with different optical input sensitivity. (See

specifications for complete information)

7705OE-HD -15 dBm input sensitivity

7705OE-HD-L -22 dBm input sensitivity

Features:

•Operation from 19.4Mb/s to 1.5Gb/s

- Reclocking for SMPTE 292M (1.485Gb/s)

SMPTE 305M, SMPTE 310M, M2S, DVB-ASI, etc.

•Supports single-mode and multi-mode fiber optic cable

•Fully hot-swappable from front of frame with no fiber or BNC disconnect/reconnect required

•Can be housed in either a 1RU frame which will hold up to 3 modules, a 3RU frame which will hold

up to 15 modules, 3RU portable frame that holds up to 7 modules or a standalone frame which will

hold 1 module

•Comprehensive signal and card status monitoring via four digit card edge display

Input:

•Optical input range from 1270nm to 1610nm

•Input sensitivity up to -23dBm

•SC/PC, ST/PC, FC/PC connector options

Outputs:

•Three serial digital BNC outputs for fan-out, loop-through or monitoring

•Wideband Jitter < 0.2 UI (reclocked)

Status LEDs:

•Signal presence indication

•Module status indication

2. INSTALLATION

The 7705OE-HD comes with a companion rear plate that has 3 BNC connectors and 1 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 section 3 of the 7700FR chapter.

Figure 2-1: 7705OE-HD Rear Panels

HD INPUT: There is a SC/PC (shown) ST/PC or FC/PC female connector for optical 10-bit serial

digital video signals compatible with the SMPTE 292M standard. The 7705OE-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 any other signal 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 three 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.

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

2mW, and wavelengths of 1310nm or from either 1270nm 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.

7705OE-HD - 8 Revision 1.6

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.

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 A and B boards remove the jumper and re-install it so that

only one side is connected.
