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
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.
