The “H7” transceiver is Class I Laser product while the “H8” transceiver is Class 1M Laser product per international IEC-825 standards. The DTR-1250-SM-GB-HS product family of GBICs provides very long haul, single mode solutions for 1000BASE-LX Gigabit Ethernet ports in a networking switch. OCP offers two optical link power budget options to support 110km (H7) and 120km (H8) in the networking infrastructure. Both options use 1550nm DFB lasers and ultra high sensitivity Avalanche Photodiode (APD) receivers to provide minimum optical link power budgets of 30dB and 32dB. They correspond to transmission distances of 110km and 120km, respectively, assuming a total connector and splice loss of 2dB, total system penalty of 3dB and fiber loss of 0.22dB/km. All transceivers are The DTR-1250-SM-GB-HS transceivers connect to standard 20-pad GBIC connectors for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different types of GBICs without removing the power supply from the host system. The transceivers operate from a single +5V power supply over an operating case temperature range of -5°C to +70°C.

The two ground tabs make contact to the host circuit ground before the connector pad and discharge any possible component-damaging static electricity. Additionally, surge currents are eliminated by using a special slow start circuit and two-stage contact sequence where operational signals and grounds make contact prior to the power supply (as specified in the GBIC specification, Rev. 5.5). TX_DISABLE: When the TX_DISABLE pin is at logic HIGH, the transmitter optical output is disabled (less than -35dBm). Serial Identification: The DTR-1250-SM-GB-HS transceivers are compliant with Annex D (Module Definition 4) of the GBIC specification, Rev. 5.5, which defines the Serial Identification Protocol. The module definition of GBIC is indicated by the three module definition pins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2). Module Definition 4 specifies a serial definition protocol with a two-wire I2C serial interface; upon power up, MOD_DEF(1:2) appear as NC (no connection), and MOD_DEF(0) is TTL LOW. When the host system detects this condition, it activates the serial protocol and generates the serial clock signal (SCL). The negative edge clocks data from the GBIC EEPROM. Electrical interface: All signal interfaces are compliant with the GBIC specification, Rev. 5.5. The high speed DATA interface is differential AC-coupled and can be directly connected to either a 5V or 3.3V SERDES IC. All low speed control and sense input/output signals are open collector TTL compatible and should be pulled up with a 4.7 - 10kΩ resistor on the host board. The serial data signal (SDA) is for serial data transfer. The host uses SDA in conjunction with SCL to mark the start and end of serial protocol activation. RX_LOS: The RX LOSS OF SIGNAL circuit monitors the level of the incoming optical signal and generates a logic HIGH when an insufficient photocurrent is produced. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in Annex D of the GBIC specification, Rev. 5.5. TX_FAULT: The output indicates LOW when the transmitter is operating normally, and HIGH when the transmitter or laser current is excessive. TX_FAULT is an open collector/drain output and should be pulled up with a 4.7 - 10kΩ resistor on the host board. 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 GBIC transceiver module as possible. 4 21737-0389, Rev.
