In addition to option “L2” for the 5 km distance specified in IEEE 802.3z standard, five other options with longer distance capability with single mode fibers are offered. In option “L1”, a 1300 nm Fabry Perot laser with higher power and narrower spectral width and center wavelength range is used to increase the distance to at least 10 km. In option “L0”, an even higher power 1300 nm Fabry Perot laser is used to offer more optical power budget. In option “H3”, a 1300 nm DFB laser and a high sensitivity receiver are used to increase the distance to over 25 km or 30 km (assuming worst case fiber loss of 0.4 dB/km and 0.35 dB/km respectively). In option “H5”, a 1550 nm DFB laser and a high sensitivity receiver are used to increase the distance to over 35 km or 40 km (assuming worst case fiber loss of 0.3 and 0.25 dB/km respectively). Finally, in option “H7”, a high power 1550 nm DFB laser and an ultra high sensitivity receiver are used to increase the distance to 70 km (assuming fiber loss of 0.2 to 0.25 dB/km). All modules satisfy Class I Laser Safety requirements in accordance with the US FDA/CDRH and international IEC-825 standards. The transmit and receive functions are contained in a narrow width two-row, 20-pin (2x10) package with a Duplex LC connector interface. The receptacle fits into an RJ-45 form factor outline. The 20-pin configuration is in conformance to a Small Form Factor (SFF) multisource agreement. The transmitter and receiver DATA interface are differential direct-coupled LV-PECL. An alternate version with AC coupling interface is also available. An LV-TTL Transmitter Disable control input is provided. The receiver Signal Detect output interface is also LV-TTL. The transceiver operates from a single +3.3V power supply over an operating temperature range of 0°C to +70°C and -40°C to +85°C. The package is made of either conductive plastic or metal for excellent EMI shielding. 3.3V 2x10 LC connector SFF Gigabit Ethernet 1300 & 1550 nm Laser Transceivers

Transmitter: When the DA TA+ input is at logic HIGH and DA TA- input is at logic LOW, the Laser Diode is ON; and vice versa. The transmitter is normally enabled (i.e. when the TX DISABLE control input is not connected). When the TX DISABLE control input voltage is higher than V CC - 1.3 V , the laser is turned off independent of the input data. The transmitter incorporates an Average Power Control (APC) loop to stabilize the transmitter average optical output power against temperature variation. The APC loop always acts to keep the transmitter average optical output power at a constant value. Therefore, when the input data is all continuous “zeroes” or all continuous “ones”, the transmitter optical output power is a constant level equal to thenominal average optical output power (not at the “OFF” level or at the “ON” level). 200 Ω10 Ω PD Imon Ib LD 3 ΚΩ 3 ΚΩ FM+BM+ VCCVCC GNDGND FM-BM- 3 ΚΩ 3 ΚΩ Application Notes Receiver: Both differential DATA+ and DATA- outputs are LV- PECL levels requiring proper termination (see recommended interface circuits). For optimum performance, both outputs should be terminated in the same manner, even if only one is used. The Signal Detect circuit monitors the level of the incoming optical signal and generates a logic LOW signal when insufficient photocurrent is produced. If the SIGNAL DETECT output is LV-TTL level, no termination is required. If the SIGNAL DETECT output is LV-PECL level, a termination resistor of 160 ohms to GND is required.

Ordering Information
Interface circuit : Three options for interface circuit are shown here: two with DC coupling and one with AC coupling. The power supply line should be well- filtered. All 0.1 µF power supply bypass capacitors should be as close to the DTR transceiver module as possible. The two front GND posts (mounting studs) should be grounded to Chassis Ground. If Chassis Ground is not available, they should be connected to Circuit Ground.
