Description

The DTR-2488-SM2-LC/LS-W-G-MR SFF series of multi-

rate fiber optic transceivers provide a quick and reliable

interface for SONET/SDH OC-48/STM-16 short reach and

intermediate reach applications. The transceivers are designed

to operate from Fast Ethernet data rate (125Mb/s) to SONET/

SDH OC-48/STM-16 (2.488Gb/s). They are compliant with

OC-48/STM-16 SONET/SDH specifications. The short reach

(SR-1) version uses a 1310nm Fabry Perot laser while the

intermediate reach (IR-1) version uses a 1310nm DFB laser

to achieve reaches of 2km and 15km, respectively. For

intermediate reach (IR-2) version, a 1550nm DFB laser is used

to obtain the reach of 15km. 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

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 to convert

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 or

-40 °C to +85 °C (“A” option). The package is made of metal

for excellent EMI immunity.
