Application

As data centers continue to scale in speed and density, electrical interconnect losses and power consumption have become critical challenges for system performance. Co-Packaged Optics (CPO) addresses these challenges by bringing optical engines closer to semiconductor packages, enabling high-bandwidth, energy-efficient communications.
Through reflow-resistant MT Ferrule technology, ferrule designs optimized for high-density integration, and custom solutions for silicon photonics applications, Hakusan Inc. supports the implementation and volume production of CPO architectures.

  80µm MT Ferrule (MTRCF™)

  This MT Ferrule is for reduced cladding fibers with a φ80µm clad, ideal for silicon photonics and CPO internal arrangements. It uses a general-purpose guide pin standard and has a 250µm fiber pin, ensuring compatibility with existing MT Ferrule while achieving high-density mounting and flexibility in wiring design.

• 

  Narrow-Pitch MT Ferrule (MTDS®)

  Compatible with reduced cladding clad φ80µm fibers, it achieves high-density packaging of 24 to 32-Fiber in a row at a fiber pitch of 125µm/127µm. It maintains compatibility with the guide pins of conventional MT Ferrule and is ideal for next-generation optical connections such as backplanes and CPO/OBO.

• 

  Reflowable MT Ferrule (MTHR®)

  The high heat-resistant structure can withstand reflow at 260°C, and maintains high fiber hole position accuracy (eccentricity of 0.7µm or less) even after the reflow process. Compatible with 12/16/24 24-Fiber-mode Single-mode, this MT Ferrule combines the reliability and precision required for high-density mounting of next-generation optical devices.

• 

  Ceramic Multifiber ferrule (CMF®)

  The highly heat-resistant ceramic structure maintains a stable shape even at high-temperature reflow temperatures of over 260°C. Customizable thicknesses of 0.5 to 1.2 mm and high-precision connections enable an IL of 0.7 dB or less, making it suitable for use in ELSFP high-power laser applications and in fields such as aerospace where high reliability is required.

  PMT connector for polymer optical waveguide

  This optical connector is compatible with polymer optical waveguides, and is designed for mounting environments that require high-density Optical Interconnect. MT Ferrule compatible interface enables narrow-pitch, low-loss wiring designs, and is also flexible for on-board optical connections and CPO configurations.

• 

  MTCT® Connector

  This optical connector is suitable for relay connections around optical modules. Its thin, short structure eliminates the need for adapters, saving space, and its reassemblable structure and compact, high-precision ferrules enable low-loss connections, increasing connection flexibility and manufacturing efficiency around optical modules in CPO configurations.

• 

  Expanded Beam Connector (GrinEB® Connector)

  This non-contact optical connector has an expanded beam structure that reduces spring pressure and extends its lifespan. Its dust-free design reduces maintenance burden and is expected to be used in harsh environments such as immersion cooling systems, aerospace, and industrial applications.
