Introduction

The TIA-3000 Optical to Electrical Converter is a convenient high bandwidth detection system for

ber optic applications. With a typical bandwidth of 30 KHz to 10 GHz, it accurately provides an elec-

trical replica of the optical signal presented to it. It is intended to drive a 50 ohm cable terminated in

its characteristic impedance.

The unit is equipped with an InGaAs/InP detector that is responsive in the wavelength range of 900

- 1700 nm. The TIA-3000 is provided with an FC ber optic receptacle. Other ber optic connectors

can be provided on request. The output signal is presented to a type K SMA female connector.

Each unit is powered by an external 9 V wall-mount power supply.

Unpacking and Inspection

Prior to shipment this instrument was inspected and found to be free of mechanical and electrical

defects. Upon acceptance by the carrier he assumes responsibility for its safe arrival. After unpack-

ing, examine the unit for any evidence of shipping damage. Should you receive this instrument in a

damaged condition, apparent or concealed, it must be noted on the freight bill or express receipt and

signed by the carrier’s agent. Failure to do so could result in the carrier refusing to honor the claim.

Upon ling a claim TTI should be notied.

Power Supply

Each unit comes equipped with a 9V regulated power supply that provides power to the unit. Simply

plug the power supply output cable into the receptacle located beneath the FC ber optic connector.

It is recommended that the user never attempt substitution of this unit with any other power

supply. Reverse polarity or voltages other than 9 Volts may irreparably damage the unit.

Calibration - This is a qualitative measurement device. No calibration is required or necessary.

The TIA-3000 is comprised of a ber coupled InGaAs detector coupled with a reverse bias voltage

network and fast transimpedance amplier. The output of the unit brought out to a type K female SMA

connector. Light falling on the detector generates a positive-going proportional current. This current,

multiplied by the transimpedance produces a voltage that is proportional to the light incident on the

detector surface.

Normally the unit is used to drive a coaxial cable, this cable should have a 50 ohm characteristic

impedance and be terminated with a 50 ohm load at the oscilloscope or other measuring device to be

used.

The active area of the TIA-3000 is 50 microns in diameter. Standard coupling ber is 9µm. Special

orders with 50µm coupling ber for use with multimode systems are available.

The TIA-3000 is normally equipped with FC/UPC connectors. Optionally the unit may be ordered with

FC/APC connectors but return loss will be dominated by reections from the detector.

Turn on sequence:

1. Ground via SMA

2. Turn on the TIA-3000

3. Connect optical power

Turn o󰀨 sequence:

1. Remove optical power

2. Turn off TIA-3000

3. Disconnect ground through SMA

Failure to operate the TIA-3000 as directed will void the warranty
