Optical module structural components, as the core components of optical communication systems, are applied in a wide range of scenarios, from data centers to telecommunication networks, enterprise-level communications, and even in special environments. The following is an analysis of the main application fields and specific scenarios of optical module structural components

I. Data Center: The Cornerstone of High-speed Interconnection

Interconnection of servers within the rack

Application scenario: High-speed data transmission between servers and switches within a data center.

Miniaturization and high density: It adopts compact packages such as SFP-DD and QSFP-DD, supporting single-module 400G/800G rates and enhancing port density.

Low-power design: Reduce energy consumption through silicon photonics technology or CPO (Optoelectronic Co-packaging) to meet the strict energy efficiency requirements of AI computing power clusters.

Thermal management: The combination of the metal casing and the heat sink ensures the stability of high-power modules (such as 800G modules with a power consumption of up to 15W) under dense deployment.

Interconnection between Data Centers (DCI

Application scenario: Long-distance optical fiber transmission across data centers (typically ≤80km).

Structural component requirements

Coherent optical module: Integrating DSP chip and tunable laser, it supports DWDM (Dense Wavelength Division Multiplexing) technology, achieving multi-wavelength multiplexing on a single fiber and enhancing transmission capacity.

High-sensitivity detector: It adopts APD (Avalanche Photodiode) to enhance the receiving sensitivity and compensate for signal attenuation during long-distance transmission.

Ii. Telecommunication Network: The Bridge between the backbone and access

5G fronthaul and midhaul

Application scenario: Optical fiber transmission between 5G base stations (AAU) and DU/CU.
