Description

The DTR-2488-SM2-LC/LS-W-G-CWDM SFF series of fiber

optic transceivers provide a quick and reliable interface for

intermediate reach (IR-2) and long reach (LR-2) applications.

Products under this series are compliant with SONET/SDH

OC-48/STM-16 (2.488Gb/s) standards for IR-2/S-16.2

intermediate reach and LR-2/L-16.2 long reach applications

,and are available in eight (8) wavelengths: 1470nm, 1490nm,

1510nm, 1530nm, 1550nm, 1570nm, 1590nm and 1610nm. Two

performance options are available. In option L0, a guaranteed

minimum optical power of -5dBm is offered with a PIN receiver

that corresponds to a link distance of 15km (assuming fiber loss

of 0.25dB/km). In option HP, a guaranteed minimum optical

power of -2dBm is offered with an APD receiver that corresponds

to a link distance of 80km (assuming fiber loss of 0.25dB/km). All

modules satisfy Class I Laser Safety requirements in accordance

with the U.S. FDA/CDRH and international IEC-60825 standards.

The transmit and receive functions are contained in a narrow

Features

width two-row, 20-pin (2x10) package with a duplex LC optical

interface. The receptacle fits into an RJ-45 form factor outline.

The 20-pin configuration is in conformance to the SFF MSA.

The transmitter design incorporates all the necessary control

and driver circuitry for converting differential data to light.

The receiver uses an InGaAs/InP PIN photodiode for IR-2

applications and an APD photodiode for LR-2 applications to

covert the light signal into an electrical current which is

amplified and regenerated into differential data outputs. AC-

coupled transmit and receive DATA interface is recommended

for compatibility with LV-PECL signal levels. An option for

DC-coupled interface is also available. LV-TTL SIGNAL

DETECT function which indicates loss of optical input is

also provided.

The transceivers operate from a single +3.3V power supply

over an operating case temperature range of -5°C to +70°C.

The package is made of metal for excellent EMI immunity.
