GPON optical modules typically output between +0. 5 dBm and +5 dBm, depending on the module class and manufacturer.

GPO

N (Gigabit Passive Optical Network) modules transmit data over optical fiber using specific wavelengths: 1490 nm for downstream and 1310 nm for upstream signals. The optical output power of these modules is standardized according to ITU-T G. 984 recommendations, with common classes including Class B+, which is widely used in GPON deployments.

Class B+ modules generally have a downstream optical output power of +0. 5 dBm to +5 dBm and a receiver sensitivity of around -28 dBm. Key points about GPON optical module output: Downstream (OLT to ONU/ONT): Typically +0.

5 dBm to +5 dBm for Class B+ modules, allowing a maximum reach of up to 20 km with standard split ratios (e.g., 1: 32) and optical budget considerations. Upstream (ONU/ONT to OLT): Burst-mode transmission with lower power, usually ranging from 0 dBm to +5 dBm, depending on the ONU class and distance to the OLT. Wavelengths: Downstream at 1490 nm, upstream at 1310 nm, with GPON using WDM to separate signals on the same fiber.

Optical budget: The difference between transmitter output and receiver sensitivity determines the maximum distance and split ratio supported. For Class B+ modules, the optical budget is typically around 28 dB, sufficient for standard GPON deployments. In practice, the exact output power may vary slightly depending on the manufacturer and module type, but the +0.

5 dBm to +5 dBm range is standard for most GPON OLT modules, ensuring reliable signal delivery to multiple ONUs over passive optical splitters.
