Description
The DTR-1250-SM series of fiber optic transceivers provide
a quick and reliable interface for 1000BASE-LX Gigabit
Ethernet applications. In addition to option “L2” for the 5km
distance specified in IEEE 802.3z Draft D5.0, five other options
with longer distance capability are offered. Option “L1” uses
a high power 1310nm Fabry Perot laser with narrower spectral
width and center wavelength range to increase the distance to
at least 10km. Option “L0” uses an even higher power 1310nm
Fabry Perot laser to offer more optical link power budget.
Option “H3” uses a 1310nm DFB laser and a high sensitivity
receiver to increase the distance to 30km (assuming fiber loss
of 0.35dB/km). Option “H5” uses a 1550nm DFB laser and a
high sensitivity receiver to increase the distance to over 40km
(assuming fiber loss of 0.25dB/km). Finally, option “H7” uses
a high power 1550nm DFB laser and an ultra high sensitivity
receiver to increase the distance to 70km (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-825 standards.
The transmit and receive functions are contained in a single
one-row, 9-pin (1x9) package with a Duplex SC, ST or FC
optical interface. The transceiver package is made of either
PCI-mezzanine-compliant conductive plastic (Duplex SC
version) with blue coloring or metal (ST and FC version) for
excellent EMI shielding.
The transmitter and receiver data interfaces are differential
direct-coupled PECL. An alternate version with AC coupling
interface is also available. The receiver signal detect output
interface is direct-coupled PECL.
The transceivers operate from a single +5V power supply over
an operating case temperature range of 0°C to +70°C. A low
power consumption version with 3.3 V supply voltage is also
offered. Please refer to the DTR-1250-3.3-SM data sheet.
