Description
The DTR-2488-SM2-LC/LS-W-G-CWDM SFF series of fiber
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.
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 anAPD receiver that corresponds
to a link distance of80km (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 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 anAPD 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 DATAinterface 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.
The transmit and receive functions are contained in a narrow
