Wave Solder Process Compatible 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. 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 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 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. 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 termination resistors for the transmitter should be close to the DTR transceiver module. The termination resistors for the receiver (50 ohms to VCC - 2 volts or the Thevenin equivalent resistors shown) should be close to the PHY or SERDES IC (which receives the DATA outputs from the receiver).
