SAFETY

Safety Precautions

The optical emissions from the units are laser-based and may present eye hazards if improperly used. NEVER USE ANY
KIND OF OPTICAL INSTRUMENT TO VIEW THE OPTICAL OUTPUT OF THE UNIT. Be careful when

working with optical fibers. Fibers can cause painful injury if they penetrate the skin.

Laser Safety Procedure

GENERAL FEATURES

The Olson OTDV-1250 Video/Stereo Audio, Data and Ethernet Fiber Optic Link provides a very high-quality system for
transporting baseband NTSC RS-250 or PAL B, D, G, H and I video signals, stereo audio signals and bidirectional data
with complete EMI immunity via multimode or single-mode optical fiber. The combination of video, stereo quality audio,
data for touch screens, pan, tilt & zoom or pure data transport for communications and the addition of au to-negotiating
10/100Mb/s Ethernet make these links ideal for broadcast, contribution and distribution quality V/A/A transport, tele­conferencing, distance learning, and surveillance applications. Each unit is built in a rugged, shielded enclosure. Units
are available with four channels of audio and unidirectional transport options.

The defining feature of the OTDV-1250 is versatility. While there are numerous fiber optic broadcast transport links
available, the addition of user/field-swappable SFP modules allows the unit to be rapidly reconfigured for any conceiv­able fiber requirement

All signals are handled using state-of-the-art digital techniques resulting in no degradation in performance regardless of
the fiber type and distance. All signals are digitized to a single serial data stream that easily fits into Gb/s data stream.
Extensive use of overhead messaging allows the two units to be aware of problems at the far end.

TRANSMIT SIDE

The left side is the transmit side. J1 is the composite video transmit. J2 is the S-video transmit. J3 is the stereo audio
transmit. The right side is the receive side. J4 is the composite video receive. J5 is the S-video receive. J6 is the stereo
audio receive. D1, D2, D3 & D4 give the status of the unit. Switch S1 selects whether the audio input is configured to be
high impedance or 600 Ohms.

POWER, DATA, ETHERNET, AND OPTICS SIDE

The left side is the power and alarm section. Pins 1 & 2 of J7 are the DC power input. Pins 3 and 4 are the alarm output.
The center section is the data interface. J8 is the low-speed data interface. Switch S2 is used to select RS-232 or RS-422.
J9 is the bidirectional 10/100Mb/s Ethernet data port. The right side con tains the SFP module interface (J10) and the unit
status LED (D5).

Model OTDV-1250, 025-000571 Rev. X5 4 www.olsontech.com

Alarm Output Specifications:

The alarm output is driven by a normally closed MOSFET. It should be pulled to an external voltage (50V max) through
a resistor. The MOSFET has a typical “on” resistance of 330 ohms. The external resistor should be chosen such that the
maximum current is less than 25mA.

The alarm output is at high impedance when the unit is functioning properly, and at low impedance when there is no
power or no optical signal is present at the receiver, or the SFP is missing.

2) The output level will track the input level.

3) The standard transceiver model offers either two or four audio channels.

4) Input impedance is switch selectable by the user. The high impedance setting is single end input.

5) The data protocol is switch selectable by the user.

6) The OTDV-1250 utilizes high-efficiency switching power supplies internally. The power dissipation is nearly

constant as the input voltage changes. The highest curr ent draw will occur at the lowest input voltage and vice
versa. Note that excessive noise and ripple on the power supply may degrade some of the performance parame­ters.

INSTALLATION

Optical Connectors

There are many optical connectors on the market. The OTDV-1250 offers LC and SC/UPC types of connectors. One of
the most common errors encountered in the field is the use of th e wrong type of connectors. The most common is using
SC/PC (Flat) with SC/APC(angled). The connectors will fit together but the optical loss will be high and performance is
unpredictable and both connectors may be permanently damaged.

Cleaning Optical Connectors

Fiber optic connectors should be clean and capped, so one can usually remove the cap and make the connection without
cleaning the connector but if there is any doubt, clean the optical conn ectors b efore making the connectio n. After making
the connection, there is no need clean the connector while the connector remains connected. Use caution when handling
the connectors. Any grease from your finger, scratches or small pieces of dust can strongly affect performance. To clean,
use a lint-free wipe such as Kimwipes or cotton swab, moisten with alcohol and gently wipe the tip of the connector. Let
the connector air dry completely or use dry compressed air to dry. When making the connection, be sure the key aligns
with the bulkhead connector. With LC connectors, gently press in until the connector “clicks” in to place.
