Optical attenuators are commonly used in, either to test power level margins by temporarily adding a calibrated amount of signal loss, or installed permanently to properly match transmitter and receiver levels. They are usually installed at the transmit end of active modules, such as OTU and OSC boards, to prevent the downstream receiver modules from being burnt due to excessively high output optical power. Transmitter power (TP) = 3dBm Receiver maximum optical input power (MP) = -6dBm Total losses (TL) = 5dB Minimum attenuation required = MP + TL – TP = -6dBm + 5dB – 3dBm = – 4 dB At a minimum, a 4 dB attenuator is required.

The OLT is the core component of the optical access network, which is equivalent to a switch or router in a traditional communication network, and is also a multi-service providing platform. OLT (Optical Line Terminal): - Function: OLT is a key component in a Passive Optical. When you stream a 4K video, join a remote meeting, or play an online game on a gigabit fiber connection, an OLT. Are you asking about an ONT (Optical Network Terminal) or sometimes called a ONU (Optical Network Unit)? Because and OLT (Optical Line Terminal) isn't typically seen anywhere but at an ISP.
