COMMUNICATIONS MODULES & SUBSYSTEMS Key Features • SFP MSA compatible Fully OC-48 SONET compliant at all reaches: SR, IR-1, IR-2, LR-1, and LR-2 Microprocessor-based design fully implements the Digital Diagnostic Monitoring Interface Automatic output power and extinction ratio control over temperature and lifetime to compensate for laser efficiency degradation Both PIN and APD versions meet -27 dB receiver reflectance Optical parameters tuned and optimized over temperature in production test Expandable options such as coarse wavelength division multiplexing (CWDM) and a custom software user interface The JDSU CT2 Series OC-48 (2.5 Gb/s) transceiver module integrates optics and electronics in a Small Form Factor Pluggable (SFP) package. It is Mult isource Agreement (MSA) compatible and designed for operation at 1310 nmand 1550 nm. Although optimized for OC-48, it provides multi-rate capabilities and can be used from OC-3 (155 Mb/s) up to 2.7 Gb/s. The CT2 Series SFP transceiver provides a fully OC-48 SONET compliant interface between the SONET/SDH photonic layer and the electrical layer. Its microprocessor-based modular design imple ments all features specified in the SFP MSA compatible 2-wire Serial Digital Diagnostic Monitoring Interface for Optical Transceivers. The major components in this module include a Fabry-Perot or uncooled distributed feedback (DFB) based optical transmitter, a PIN or APD based optical receiver with integrated transimpedence amplifier (TIA), an APD high voltage circuit (if required), a microprocessor, a limiting post amplifier, and a laser driver. The modular transceiver design offers a "hot-pluggable" int erface, allowing the same basic architecture to be used for SR, IR-1, IR-2, LR-1, and LR-2 versions.

Transceiver Pin Descriptions Pin Description TD Un-clocked, multirate, differential serial bit stream (155 Mb/s to 2.7 Gb/s) used to drive the optical transmitter. TDb Internally AC coupled and terminated via internal 100 Ω differential impedence. RD Differential received electrical signal capable of detecting 155 Mb/s to 2.7 Gb/s bit patterns. RDb The differential pair is internally biased and AC coupled. This signal requires 100 Ω external differential termination. Rate_select Internally monitored and available for future use. Can be customized for specific applications. TxDIS Transmitter Disable Input. A logic HIGH on this input pin disables the transmitter's laser so that there is no optical output. If left open the transmitter will be disabled. LOS Loss of Signal (Open Collector). A logic HIGH on this output indicates an incoming signal level that is less than -25 dBm but no greater than -31 dBm for IR and SR configurations and less than -34 dBm but no greater than -40 dBm for LR configurations. LOS shall deassert (logic LOW) when a 3 dB (maximum), 0.5 dB (minimum) hysteresis is obtained. Tx_fault Transmitter fault (Open collector). A logic HIGH indicates that the transmitter is in a fault condition. MOD_DEF(0) MOD_DEF(0) is internally grounded to indicate the presence of the module. Must be pulled-up on host board with 10 KΩ resistor. MOD_DEF(1) MOD_DEF(1) is the clock of the 2 wire interface for module monitoring. MOD_DEF(2) MOD_DEF(2) is the data line of the 2 wire interface for module monitoring.

Measured as fiber coupled power into a standard single mode fiber, typical connector repeatability is ±1 dB. LC duplex cables m anufactured by Stratos are not recommended due to a potentially larger window of repeatability. 2. Full spectral width measured 20 dB down from the central wavelength peak under fully modulated conditions. 3. Ratio of the average output power in the dominant longitudinal mode to the power in the most significant side mode in fully mo dulated conditions. 4. Ratio of logic 1 output power to logic 0 output power under fully modulated conditions with a PRBS 23 data pattern. 5. GR-253-CORE, ITU-T, Recommendation G.957. T ested at STM1, STM4, STM16. 6. Formatted OC-48 pattern with scrambled PRBS payload using an Agilent OmniBer as the optical source driving the CT2 optical re ceiver. The differential data outputs of this optical receiver are used as the electrical inputs for the CT2 transmitter which optically drives the OmniBer receiver input to complete the jitter test circuit. This is a 60 second test as recommended in GR-253.
