General Description<\/h2>\n

\u00a0<\/p>\n

WDS5441H-C(H)3AL is a high performance transceiver\u00a0 module\u00a0 for\u00a0 single\u00a0 fiber communications\u00a0 using\u00a0 a\u00a0 1490nm continuous-mode transmitter and a 1310nm burst-mode receiver. It is designed to meet CTC 3.0 and IEEE802.3ah -2004 1000BASE- PX20+++ applications.<\/p>\n

The transmitter has automatic power control (APC) function and temperature compensation circuitry to ensure stable optical power output and extinction ratio over all operating temperature range. The transmitter meets Class 1 eye safety per IEC825 and CDRH standards.<\/p>\n

The receiver has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with LVPECL compatible differential outputs. It features a burst-mode Loss of signal (LOS) output which is LVTTL compatible. The receiver offers bust-mode RSSI outputs, which is I2C<\/p>\n

accessible digitized data stored in the internal flash memory.<\/p>\n

The module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias current, module temperature, supply voltage, and burst-mode receiving power. Calibration and alarm\/warning threshold data are written and stored in the internal memory (EEPROM). The memory map is compatible with SFF-8472.<\/p>\n

  1. TX Fault is an open collector\/drain output, which should be pulled up with a 4.7K\u201310K\u2126 resistor on the host board. Pull up voltage between 2.0V to VccT+0.3V or VccR+0.3V. High output indicates a laser fault of some kinds. Low indicates normal operation. In the low state, the output voltage will be below 0.8V.<\/li>\n
  2. TX disable is an input that is used to control the transmitter power output. It is pulled up within the module with a 4.7\u201310 K\u2126 resistor. Its states are: Low (0 \u2013 0.8V): Transmitter on; (>0.8, < 2.0V):<\/li>\n<\/ol>\n

              GEPON OLT PON Module,Class C++, 7dBi, 20Km<\/strong><\/p>\n

              WDS5441H-C(H)3AL<\/strong> is a high performance transceiver module for single fiber communications using a 1490nm continuous-mode transmitter and a 1310nm burst-mode receiver. It is designed to meet CTC 3.0 and IEEE802.3ah -2004 1000BASE- PX20+++ applications.
              \nThe transmitter has automatic power control (APC) function and temperature compensation circuitry to ensure stable optical power output and extinction ratio over all operating temperature range. The transmitter meets Class 1 eye safety per IEC825 and CDRH standards.
              \nThe receiver has a hermetically packaged APD-TIA (trans-impedance amplifier) pre-amplifier and a limiting amplifier with LVPECL compatible differential outputs. It features a burst-mode Loss of signal (LOS) output which is LVTTL compatible. The receiver offers bust-mode RSSI outputs, which is I2C
              \naccessible digitized data stored in the internal flash memory.
              \nThe module provides digital diagnostic information of its operating conditions and status, including transmitting power, laser bias current, module temperature, supply voltage, and burst-mode receiving power. Calibration and alarm\/warning threshold data are written and stored in the internal memory (EEPROM). The memory map is compatible with SFF-8472.
              \nCompatible with all Wodaplug OLT units and all other with this standard<\/strong><\/span><\/p>\n
