Whether in 5G base stations, hyperscale data centers, or long-haul telecom networks, these modules convert electrical signals into optical ones —
The optical module serves as a crucial component in optical fiber communication systems, operating at the physical layer, which is the lowest layer in the OSI model. Its working principle can be simplified as: - Transmit End (Electrical → Optical): Converts electrical. In the era of 5G, AI, and high-speed data centers, optical modules serve as the core bridge for converting electrical signals to optical signals (and vice versa), enabling fast, reliable data transmission across networks.
