Optical Module Upstream and Downstream Map
For TDM-PON, a passive optical splitter is used in the optical distribution network. In the upstream direction, each ONU (optical network units) or ONT (optical network terminal) burst transmits for an assigned time-slot (multiplexed in the time domain). In this way, the OLT is receiving signals from only one ONU or ONT at any point in time. In the downstream direction, the OLT (usually) continuously transmits (or may burst transmit). ONUs or ONTs see their own data through the address labels embe.

What causes the high beam module to overheat
The reasons for high-temperature operation of optical modules are complex and varied, including both design and quality issues of the equipment itself, as well as external factors such as environmental conditions and operating loads. Heat stress remains one of the main reasons why IGBT modules degrade over time, impacting how long they last and whether they work reliably. Most of the time, overheating. While they're designed to operate within specified temperature ranges, running a module above its rated operating temperature causes measurable performance degradation and can lead to permanent failure.
