XMT5170 XMT5370 Laser Transmitter Datasheet

XMT5170, XMT5370 Logic Interface Laser Transmitter

This application note details the recommended circuit connections for the XMT5170, XMT5370 laser transmitter. The XMT5170, XMT5370 is a multisourced SONET/SDH laser transmitter. The device will operate from a single supply rail with the XMT5170A, XMT5370A version specified for -40°C to +85°C operation and the XMT5170B, XMT5370B version operated from 0°C to +70°C.

Evaluation Board (Part No. 101017.000)
Hewlett-Packard supplies an evaluation board , as shown, to provide power and interface connections to the device.

The evaluation board operates from between - 8 V and -15 V bias. This voltage is regulated for the device supply rail. Adjustment of potentiometer VR1 will adjust the module supply rail to enable testing over the specified range (-4.75 V to -5.5 V). The bias monitor (IB MON) and rear facet monitor (IM MON) are accessible via a connector mounted on the pcb.
