The 400GBASE-SR4 OSFP transceiveris an 400Gb/s Single-port OSFP, SR4 multimode parallel transceiver using a single, 4-channel MPO-12/APC optical connector. The Short Reach 4-channel (SR4) design uses 100G-PAM4 modulation and has a maximum fiber reach of 50-meters using OM4 multimode fibers. It is qualified for use in end-to-end systems. It is the ideal solution for supercomputing, seamlessly integrating into computing and storage infrastructure to ensure efficient high-performance interconnectivity. Used in ConnectX-7/OSFP adapters linked to Twin-port transceivers in 2x400G switches.

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.
