1 OC-/STM- SFP CWDM Transceivers with Digital Diagnostics TRPE0-G CWDM Pb Product Description The TRPE0-G CWDM SFP series of fiber optic transceivers with integrated digital diagnostics monitoring functionality provide a quick and reliable interface for long reach (LR) applications. The diagnostic functions, alarm and warning features as described in the Multi- Source Agreement (MSA) document, SFF-7 (Rev.9.), are provided via an I C serial interface. Products under this series are compatible with SONET/SDH standards for OC-/STM- LR-/L-. and are available in eight () wavelengths: 7nm, 9nm, nm, nm, nm, 7nm, 9nm and nm. Two optical link power budgets are available, db and db, providing an extra db and db over SONET/SDH link budgets, respectively, to accommodate the wavelength multiplexing and de-multiplexing insertion losses. All modules satisfy Class I Laser Safety requirements in accordance with the U.S. FDA/CDRH and international IEC-0 standards. The TRPE0-G CWDM transceivers connect to standard 0-pad connectors 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 transceivers have colored bail-type latches, which offer an easy and convenient way to release the modules. 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 transceivers operate from a single +.V power supply over an operating case temperature range of - C to +70 C (Commercial) or - C to + C (Extended). 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 SERDES 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 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 EEPROM 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 start and 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 SFPMSA, and SFF-7, Rev. 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. S00. Rev0. (web) 0.0.
