11. Capa de Aplicación ( interfaz de usuario ) ( continuación …) Comandos generales ( registros 0x00 a 0x1F) Comandos reservados para CW Laser ( registros 0x20 a 0x7F) Comandos del fabricante ( registros 0x80 a 0xFF) El direccionamiento extendido provee un espacio de memoria adicional ( dirección de 22 bits) a los 256 registros principals ( espacio de direccionamiento de 8-bit). El mismo consiste de tres registros : Configuration Register :  Define la configuración básica para el direccionamiento extendido como el espacio de direccionamiento al cual está siendo referenciado ( ej . Espacio de registro , espacio de Código, espacio de datos , etc ). Address Register :  Define la dirección para la locación de memoria a ser referenciada . Content Register :   Una operación de “ lectura ” o “ escritura ” a este registro indirectamente accederá al lugar de memoria especificado por los dos registros previos .

13. Module Optical Settings Channel (Channel, ChannelH 0x30, 0x65) [RW] (ui32) La frecuencia del canal está definido por: Freq (GHz) = ( Laser_Channel – 1) * Grid_Spacing_GHz + First_Channel_Frequency_GHz + Fine_Tune_GHz . donde : Laser_Channel = ChannelH (0x65) * 2 16 + Channel (0x30) Grid_Spacing_GHz = GRID (0x34) * 10 -1 + GRID2 (0x66) * 10 -3 First_Channel_Frequency_GHz = FCF1 (0x35) * 10 3 + FCF2 (0x36) * 10 -1 + FCF3 (0x67) * 10 -3 Fine_Tune_GHz = FTF (0x62) * 10 -3 Ejemplo : CH: 51, FCF=191,5 THz, GRID=50,0GHz => LF=194,0 THz

14. Module Optical Settings Optical Power Set Point (PWR 0x31) [RW] (i16) Generalmente el SP se configura antes de configurar el canal. Reset/Enable ( ResEna 0x32) [RW]

15. Module Optical Settings Grid Spacing (GRID - 0x34: Signed short (GHz*10) GRID2 - 0x66): Signed short (MHz) First Channel’s Frequency (FCF1 - 0x35 : U16 (THz) FCF2 - 0x36: U16 (GHz*10) FCF - 0x67): U16 (MHz) The FCF1 register has a permissible range which is manufacturer specific. The FCF2 register has a permissible range of 0 to 9999. The FCF3 register has a permissible range of 0 to 99. Laser Frequency (LF1 - 0x40 : U16 (THz) LF2 - 0x41: U16 (GHz*10) LF3 - 0x68): U16 (MHz) [R] R ead the frequency of the current channel

16. Module Optical Settings Optical Output Power (OOP 0x42) [R] S16 (dBm*100) Current Temperature ( CTemp 0x43) [R] S16 (ºC*100) Module’s Capabilities Fine Tune Frequency Range (FTFR 0x4F) U16 (MHz) This register reports the minimum and maximum fine tune frequency setting which is possible for the module. This single value covers the min/max range symmetrically about 0. For example, an FTFR of 5000 indicates that the module is capable of having a fine tune frequency adjustment of +/- 5GHz about the tuned frequency. Optical Power Min/Max Set Points (OPSL, OPSH 0x50 – 0x51) S16 (dBm*100) Laser’s First/Last Frequency (LFL1/2/3 – 0x52,0x53,0x69, LFH1/2/3 0x54, 0x55, 0x6A) The register set (LFL1/2/3) returns the lowest frequency capability of the laser. The register set (LFH1/2/3) returns the highest frequency capability of the laser.

17. Module’s Capabilities Laser’s Minimum Grid Spacing ( LGrid , LGrid2 - 0x56, 0x6B) The LGrid:LGrid2 register pair returns the laser’s minimum grid spacing as a positive value with a minimum resolution of 1MHz.
