OCP DTR-1250-SM Gigabit Ethernet 1x9 Single Mode Transceivers Features ; Compliant with IEEE 802.3z Draft D5.0 1000BASELX Specifications for Gigabit Ethernet ; Distance Options to Support 5km to 70km ; Eye Safe (Class I Laser Safety) ; Excellent EMI & ESD Protection ; Multi-sourced 1x9 Package Style ; Conductive Plastic or Metal Package ; PCI-mezzanine-compliant Conductive Plastic Package (9.8mm maximum height) ; Single +5V Power Supply & PECL Interface ; PECL Signal Detect Output ; Wave Solder Process Compatible 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.

G 05-18-04 DTR-1250-SM Application Notes DATA interface (DC-coupled module): The interface circuit for the standard DC-coupled module with direct-coupled PECL interface is shown in Figure 1. The termination resistors for the transmitter should be close to the DTR transceiver module. The termination resistors for the receiver (50Ω to VCC - 2V or the Thevenin equivalent resistors shown) should be close to the PHY or SERDES IC, which receives the DATA outputs. When interfacing with 3.3V SERDES IC, AC coupling can be used as shown in Figure 2. The termination resistors required by the SERDES are not shown in this figure. DATA interface (AC-coupled module): For modules with AC coupling option, both transmitter and receiver interfaces have internal bias, termination and AC coupling capacitors. The transmitter can be directly connected to the driving SERDES. The receiver can be connected directly to the external 50Ω load (termination resistor of the SERDES). SIGNAL DETECT: The signal detect circuit monitors the level of the incoming optical signal and generates a logic LOW signal when an insufficient photocurrent is produced. The signal detect output is PECL level requiring termination (510Ω to GND is recommended). The transmitter incorporates an Average Power Control (APC) loop to stabilize the average optical output power against temperature variation; therefore, when the input data is all continuous “zeroes” or all continuous “ones”, the transmitter optical output power is a constant level equal to the nominal average optical output power (not at the “OFF” or “ON” level). Power supply and grounding: The power supply line should be well-filtered. All 0.1µF power supply bypass capacitors should be as close to the DTR transceiver module as possible. The two front GND posts should be grounded to circuit ground or chassis ground.
