8x 100G-PAM4 to Dual 4x 100G-PAM4.

Minimum Bend Radius 72mm for Flexible Routing.

Simplifies Patching and Offers a Cost-effective Way for Short Links.

Hot Pluggable, Compliant with OSFP MSA Rev5.0, IEEE 802.3ck and CMIS 4.0.

The 800G OSFP to 2 x 400G OSFP DAC is an 800Gb/s twin-port OSFP to 2x 400Gb/s twin-port OSFP passive Direct Attached Copper dual breakout cable for 400Gb/s Ethernet solutions. It is compliant with OSFP MSA (Multi-Source Agreement) and IEEE 802.3ck standards. Each end includes an EEPROM which provides product identification and characteristics to the host system. The 8-channel twin-port OSFP end uses a finned top form-factor for use in Ethernet air-cooled switches, while the two 400G ends support 4-channels of 100G-PAM4 (400G) and use a flat top OSFP for use in Ethernet adapters using riding heat sinks on the connector cage. The main use of the cable is linking an 800G switch to OSFP-based 400G network adapter cards. Featured with low latency, low power consumption and cost-effective performance, this cable enables 800G to dual 400G breakout connections for server-to-TOR links in AI/ML training clusters, hyperscale cloud data centres, and high-performance computing environments.

Design and Simulation

Scheme Design

Industry-standard approach using an edge-coupled external light source combined with solid waveguides — a unified optical design that scales across 200G, 400G, 800G and 1.6T product families.

Single-source 1:4 and 1:8 fan-out designs, including FR-4 compatible options, to shorten development cycles and simplify integration.

Unique in-module coupling, locking mechanisms and high/low-temperature compensation algorithms that establish the foundation for high yield, low-cost mass productions.


Simulation Analysis

End-to-end simulation and analysis: full optical-path optical simulation, thermal simulation, signal-integrity (SI) simulation and 3D structural analysis.

Engineering platform supports the productization of all-silicon-photonics solutions from 200G through 1.6T.

79 granted patents specifically for silicon-photonic solutions.


Processing and Manufacturing

Fully self-developed coupling automation equipment and tri-temperature test stands, enabling flexible monthly capacity allocation and high production yields.

Production Process

Tanlink Optics Automated unmanned workshop


Step 1 Optical Engine Desigh & Production.

The optical engine is seen as the core optical component in a transceiver. The optical engine’s packaging and production are mainly achieved in automated production area through using COB (Chip on Board) technology, which comprises 3 key process: die bonding, wire bonding and coupling .



Step 2 Transceiver Assembly

All finished optical components need to be packaged in the transceiver housing.  This step is often finished in the manual production area.


.Step 3 Testing

In the test area of Tanlink's factory, each transceiver must be tested to make sure whether it is in line with the corresponding standard.  Additionally, each one must be determined whether it can resist extreme environments and circumstances.

Reliability Test

Temperature & Humidity Cycling Test  

Temperature & humidity cycling test is used for examining the ability of 

Tanlink's transceiver products to resist extremely low and extremely high temperatures and humidities.


Vibration Test

Vibration test is for determining whether our transceiver products can withstand

 various environment vibrations by simulating possible vibration environments encountered

 by the product in the process of transportation, installation and use.
