3.3.6. CTLm cable
The CTLm cable connects the HHL on one side, and splits into two connectors on
the other side: one for the TCU, the other for the laser driver. The TCU controls the
temperature of the HHL with a Peltier junction and monitors the temperature with a
PT100 temperature sensor. The TCU side of the CTLm cable is the same as the CTL
cable, as described in section 3.3.5. The laser driver connector is compatible with the
CIL cable for CW mode operation, or the LBI cable for pulsed mode operation. The
HHL side of the CTLm cable contains the female connections described in table 3.5.

Table 3.5.: CTLm cable HHL connector pinout.
The CTLm male connector for the laser driver has the same function as the LLH
laser and base connector. It consists of two rows of pins; in one row, all pins are
connected, and correspond to the laser connector (negative polarity), in the other
row, two pins are removed, and correspond to the base connector (positive polarity).
