Optical Fiber Direct Connection Cable 

Optical Fiber Direct Connection Cable (O-O-C) is a high-performance transmission medium designed specifically for all-optical communication systems. Its core function is to enable end-to-end optical signal transmission between optical fibers. Unlike traditional OEO (Opto-Electronic-Optical) relaying, this technology utilizes an all-optical transmission architecture, directly transmitting optical signals through a sophisticated optical waveguide structure, completely eliminating the signal distortion and power loss caused by optoelectronic conversion. This characteristic gives it significant advantages in long-haul transmission (such as transoceanic submarine cables) and high-density data exchange (such as data center Direct Connection Infrastructure (DCI)). Its physical basis relies on the principle of total internal reflection, utilizing 99.999% pure synthetic quartz fiber as the transmission carrier, achieving ultra-low attenuation below 0.15dB/km.

The core competitiveness of optical-to-fiber cables lies in three key areas:

First, the all-optical transparent transmission architecture eliminates electrical domain conversion, reducing energy consumption by 53% and latency by 0.3μs compared to traditional solutions in typical scenarios (using a 100km transmission distance as an example).

Second, single-mode fiber supports C+L band extension, with a theoretical transmission capacity of up to 96Tbps/fiber, perfectly suited for the high-bandwidth demands of 5G backhaul and cloud rendering.

Third, its inherent electromagnetic interference immunity enables it to maintain a bit error rate of 10^-12 even in strong electromagnetic environments (such as UHV substations). These characteristics together establish its key position in new communications infrastructure.

Current mainstream applications fall into three main areas:

1: Transoceanic communications (e.g., the SEA-ME-WE 6 system, with a 32Tbps design capacity);

2: Data center mesh interconnection (a leaf-spine architecture that meets latency requirements of <100ns);

3: Specialized scenarios (including shipborne phased array radar signal distribution and medical OCT endoscopic imaging). According to LightCounting, global deployments reached 2.7 million fiber-core kilometers by 2023, with a stable compound annual growth rate of 18.7%, fully demonstrating its irreplaceable role as a core component of information infrastructure.
