 An 8-pin Hirose connector (see <tabref TECconnectortable> for identity of connectors) carries the signals for the temperature control of the Laser module.  The wiring diagrams are shown in the table below, where 1 (2) refer to stage 1 (2) temperature control, which stabilizes the Laser Housing (Laser Diode). Rth and Rth_Rtn are the two ends of a 10 kΩ [[http://www.analogtechnologies.com/ath10kr8.html|Analog Technologies ATH10KR8 Thermistor]]. An 8-pin Hirose connector (see <tabref TECconnectortable> for identity of connectors) carries the signals for the temperature control of the Laser module.  The wiring diagrams are shown in the table below, where 1 (2) refer to stage 1 (2) temperature control, which stabilizes the Laser Housing (Laser Diode).
