2.5Gbps With Bi-directional Transceiver SWFP5261-23-1(2)25+ Transmitter Section Transmitter designed single mode fiber operates nominal wavelength 1550nm. transmitter module uses laser diode full IEC825 CDRH class safety. output power disabled single TxDis pin. Logic LVTTL HIGH level disables transmitter. contains function, temperature compensation circuit, PECL data inputs, LVTTL Txdis input fault Output interface. Receiver Section receiver section uses hermetic packaged front receiver (InGaAs preamplifier). postamplifier coupled preamplifier through capacitor pass filter. capacitor enough pass signal from 5Mb/s 2600Mb/s without significant distortion performance penalty. limits preamplifier bandwidth improve receiver sensitivity. input optical decreased, will switch from high. input optical power increased from very levels, will switch back from high low. EEPROM Section optical transceiver contains EEPROM. provides access sophisticated identification information that describes transceiver' capabilities, standard interfaces, manufacturer, other information .The serial interface uses 2-wire serial CMOS EEPROM protocol defined ATMEL AT24C01A/02/04 family components. When serial protocol activated, host generates serial clock signal (SCL, positive edge clocks data into those segments EEPROM that write protected within transceiver. negative edge clocks data from transceiver. serial data signal (SDA, bi-directional serial data transfer. host uses conjunction with mark start serial protocol activation. memories organized series 8-bit data words that addressed individually sequentially. Module provides diagnostic information about present operating conditions. transceiver generates this diagnostic data digitization internal analog signals. Calibration alarm/warning threshold data written during device manufacture. Received power monitoring, transmitted power monitoring, bias current monitoring, supply voltage monitoring temperature monitoring implemented. diagnostic data values must converted real world units using calibration constants stored EEPROM locations wire serial address A2h. digital diagnostic memory specific data field define following.
