1 OC- 0nm Optical Supervisory Channel SFP Transceiver TCE0KEC000C Product Description The TCE0KEC000C SFP fiber optic transceiver with integrated digital diagnostics monitoring functionality provides a quick and reliable interface for optical supervisory channel applications. The diagnostic functions, alarm and warning features as described in the Multi-Source Agreement (MSA) document, SFF-7 (ev. 9.), are provided via an I C serial interface. The TCE0KEC000C transceiver uses a 0nm DFB laser and an APD receiver to provide an optical link power budget of db. The transceiver satisfies Class I Laser Safety requirements in accordance with the U.S. FDA/CDH and international IEC-0 standards. The transceiver connects to a standard 0-pad connector for hot plug capability. This allows the system designer to make configuration changes or maintenance by simply plugging in different types of transceivers without removing the power supply from the host system. The transceiver has a blue bail-type latch, which offers an easy and convenient way to release the module. The latch is compliant with the SFP MSA. The transmitter and receiver DATA interfaces are AC coupled internally. LV-TTL Transmitter Disable control input and Loss of Signal output interfaces are also provided. The transceiver operates from a single +.V power supply over an operating case temperature range of - C to +70 C (COM). The housing is made of metal for EMI immunity.

The high speed DATA interface is differential AC-coupled internally with μf and can be directly connected to a.v SEDES IC. All low speed control and sense output signals are open collector TTL compatible and should be pulled up with a.7-0kω resistor on the host board Loss of Signal (LOS): The Loss of Signal circuit monitors the level of the incoming optical signal and generates a logic HIGH when an insufficient photocurrent is produced. TX_Fault: The output indicates LOW when the transmitter is operating normally, and HIGH with a laser fault including laser end-of-life. TX Fault is an open collector/drain output that should be pulled up with a.7-0kω resistor on the host board. TX Fault is latched per SFP MSA. TX_Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled (less than -dbm). Serial Identification and Monitoring: The module definition of SFP is indicated by the three module definition pins,, MOD_DEF() and MOD_DEF(). Upon power up, MOD_DEF(:) appear as NC (no connection), and is TTL LOW. When the host system detects this condition, it activates the serial protocol (standard two-wire I C serial interface) and generates the serial clock signal (SCL). The positive edge clocks data into the EEPOM segments of the SFP that are not write protected, and the negative edge clocks data from the SFP. The serial data signal (SDA) is for serial data transfer. The host uses SDA in conjunction with SCL to mark the startand end of serial protocol activation. The supported monitoring functions are internal temperature, supply voltage, bias current, transmitter power, average receiver signal, all alarms and warnings and software monitoring of TX Fault/LOS. The device is internally calibrated. The data transfer protocol and the details of the mandatory and vendor specific data structures are defined in the SFP MSA, and SFF-7, ev. 9.. Power supply and grounding: The power supply line should be well-filtered. All 0.μF power supply bypass capacitors should be as close to the transceiver module as possible , ev.a
