Extended Reach Mul ti-rate OC-48/STM-16 LR-2/L-16.2 SFP CWDM Transceivers with Digital Diagnostics
TRPE48KE2 CWDM
Pro d u c t De s c rip tio n
The TRPE48KE2 CWDM SFP series of multi-rate ber optic transceivers with digital diagnostics monitoring functionality provide a quick and reliable interface for extended reach LR-2 applications. Diagnostics monitoring functionality (alarm and warning features) is integrated into the design via an I2C serial interface per the Multi-Source Agreement (MSA) SFF-8472, Rev. 9.4. Products under this series are compatible with SONET/SDH standards for OC-48/STM-16 (2.488Gb/s) LR-2/ L-16.2 extended reach applications, OC-3/STM-1 (156Mb/s) and OC-12/STM-4 (622Mb/s) SR/I-1 and I-4 short reach applications; Gigabit Ethernet LX (1.25Gb/s) applications per IEEE 802.3; and Fibre Channel 200-SM-LC-L (2.125Gb/s) and 100-SM-LC-L (1.062Gb/s) applications per FC-PI standards. The transceivers support data rates ranging from 2.67Gb/s down to 125Mb/s and are available in eight (8) wavelengths: 1471nm, 1491nm, 1511nm, 1531nm, 1551nm, 1571nm, 1591nm and 1611nm. The higher optical link power budget of 32dB is to accommodate the wavelength multiplexing and de-multiplexing insertion losses. All transceivers are Class I Laser products per U.S. FDA/CDRH and international IEC-60825 standards. The TRPE48KE2 CWDM transceivers connect to standard 20-pad SFP connectors for hot plug capability. This allows the system designer to make con guration changes or maintenance by simply plugging in di erent types of transceivers without removing the power supply from the host system. The transceivers have colored bail-type latches, which o er 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 (LOS) output interfaces are also provided.

R: 4.7 to 10k CAP Values in F A pplication N otes Electrical interface: All signal interfaces are compliant with the SFP MSA speci cation. The high speed DATA interface is di erential AC-coupled internally with 1 F and can be directly connected to a 3.3V SERDES IC. All low speed control and sense output signals are open collector TTL compatible and should be pulled up with a 4.7 - 10k 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 insu cient 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 4.7 - 10k resistor on the host board. TX Fault in non-latching (automatically deasserts when fault goes away). TX_Disable: When the TX Disable pin is at logic HIGH, the transmitter optical output is disabled (less than -45dBm). Serial Identi cation and Monitoring: The module de nition of SFP is indicated by the three module definition pins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2).

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 (standard two-wire I2C 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 conj unction with SCL to mark the start and end of serial protocol activation. The supported monitoring functions are temperature, 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 speci c data structures are de ned in the SFP MSA, and SFF-8472, Rev. 9.4 Power Supply and Grounding: The power supply line should be well- ltered. All 0.1 F power supply bypass capacitors should be as close to the transceiver module as possible.

The indicated transmission distance is for guidelines only, not guaranteed. The exact distance is dependent on the ber loss, connector and splice loss, and allocated system penalty. Longer distances can be supported if the optical link power budget is satis ed.
