Transmitter

The transmitter section is a 1300nm LED and a driver

circuit which converts the differential, PECL digital input

signals into an proportional LED drive current. Because

the 1300nm wavelength takes advantage of the lower

dispersion and attenuation region of glass optical fiber,

this transceiver is capable of link distances of 2km at the

maximum data rate.

Receiver

The receiver optical sub-assembly consists of a InGaAs

PIN photodiode and transimpedance amplifier in an inte-

grated package to optimize performance. The resulting

analog output is coupled to a post-amplifier for signal con-

ditioning and conversion to differential, PECL high-speed

outputs.

Description

The OPF5112 from Optek is a high performance,

cost effective module for serial optical data commu-

nications applications specified for 100 Mb/s opera-

tion. This transceiver operates with +3.3V power

supply and is housed in a plastic package with an

industry standard 1 x 9 form factor.

The OPF5112 is a duplex ST transceiver designed

for use in Fast Ethernet 100 Base-FX interface. The

characterization is performed in accordance FDDI

PMD Standard. Likewise, the Fast Ethernet Alliance

defines the Physical Layer for 100 Base-FX for Fast

Ethernet to be the FDDI PMD Standard.

OPF5112 consists of a transmitter optical subas-

sembly, a receiver optical subassembly and an

electrical sub-assembly. All are housed in a plastic

package and the combination produces a compo-

nent of high performance and reliability.

OPF5112 Technical Data

Regulatory Compliance

The OPF5112, and other products from Optek, are

designed to comply with regulations governing

equipment used in information technology equip-

ment. The goal is for seamless integration of these

products into system designs with the confidence

that the requirements set forth by the certifying

body will be met. For more information, please con-

tact an Optek sales representative or applications

engineer.

Electromagnetic Interference (EMI)

EMI compliance is governed by different organiza-

tions throughout the world:

• The FCC in the United States

• CENELEC EN55022 in Europe

• VCCI in Japan

The OPF5112 has been design to comply with FCC

standards and meet the Class B limits specified

therein.

Immunity

Some locations that data communications equip-

ment is located have high levels of radio-frequency

electromagnetic fields. The OPF5112 exhibits ex-

cellent immunity to these fields.

Eye Safety

All Optek transceivers emit invisible radiation from

their optical connector ports. As such, precautions

should be taken when using these devices. Optek

transceiver products are designed to meet Class 1

eye safety guidelines and comply with EN60825-1.

Electrostatic Discharge

The OPF5112 is subject to damage from ESD.

Normal ESD handling practices should be observed

when handling this device. Grounded wrist straps,

work stations and floor mats are advised.
