Description
The DTR-1250-MM fiber optic transceiver offers a simple
and convenient way to interface 1000BASE-SX Gigabit
Ethernet boards running at 1.25 Gbaud to multimode fiber
optic cables. A high reliability 850 nm wavelength Vertical
Cavity Surface Emitting Laser (VCSEL) is used in the
transmitter. All modules satisfy Class I Laser Safety
requirements in accordance with the US FDA/CDRH and
international IEC-825 standards.
The transceiver is housed in a PCI-mezzanine-compliant (9.8
mm maximum height) one-row, 9-pin (1x9) package with
Duplex SC connector interface. The transceiver package is
made of conductive plastic to obtain excellent EMI shielding.
Optional EMI shields for making direct contact from the SC
Absolute Maximum Ratings
connector to the equipment chassis opening are also available.
The transceiver is also offered in a metal package with ST or
FC connector interface.
The transmitter and receiver DATA interface are differential
direct-coupled Pseudo Emitter Coupled Logic (PECL). An
alternate version with AC coupling interface is also available.
The receiver Signal Detect output interface is direct-coupled
Pseudo Emitter Coupled Logic (PECL).
The transceiver operates from a single +5V power supply over
an operating 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-MM data sheet.
