KDPOF designs first optical 1000BASE-RH SFP module

KDPOF has developed and validated the first 1000BASE-RH SFP module for optical gigabit connectivity in vehicles. The design of the new small form-factor pluggable transceiver module is based on a standard SFP supporting MSA registers via I2C bus. The module can operate at 100 and 1,000 Mb/s. It integrates the whole 1000BASE-RHC PHY and the header connector for SI-POF optical harness. “Our new SFP module has been tested and validated in a functional demo recently,” stated Carlos Pardo. “We are proud to accomplish the first milestone for future commercial optical 1000BASE-RH SFP modules, which will integrate into the optical ecosystem in automotive.”

Demo setup of the optical multi-gigabit system solution from KDPOF for in-vehicle connectivity

Together with several industry leaders, KDPOF is working on an optical automotive multi-gigabit system that will fulfill the needs of future connected and automated vehicles. Instead of various port components, the new solution provides a single, complete package. “As the auto industry approaches the 50 Gb/s*m speed-length threshold, the move from copper to optical physical data transmission media is becoming mandatory,” stated Carlos Pardo, CEO and Co-founder of KDPOF. “Optical is the engineering-wise path for higher data rates.” The new connector systems are very small, lightweight and extremely inexpensive compared to the previous ones. With the comprehensive EVK9351AUT evaluation kit, automotive manufacturers and suppliers can already test the new configuration at 1 Gbit/s today. KDPOF thus supports easy project entry into optical gigabit connectivity for a secure Ethernet backbone and ADAS sensor connections in vehicles. Read more

The new integrated KD9351 Fiber Optic Transceiver (FOT) from KDPOF further reduces costs for optical in-vehicle networks at 1 Gb/s. Incorporating the transmit and receive optoelectronics into one single component, the KD9351 is an optical transceiver for 100 Mb/s up to 1 Gb/s with a small footprint. “Compared to STP (shielded twisted pair of copper wires), the combination of the new KD9351 FOT with the continuing KD1053 IC cuts the cost for 1 Gb/s by 30 percent,” explained Carlos Pardo, CEO and Co-founder of KDPOF. “The new integrated device provides enhanced efficiency and flexibility. It thus paves the way to optical multi-gigabit Ethernet in the vehicle.” Applications for the new KD9351, with competitive pricing for EMC critical or galvanic isolated critical links, include safe Ethernet backbones and sensor links for advanced driver assist systems (ADAS).

KDPOF presents new integrated KD9351 FOT for automotive gigabit connectivity

New integrated KD9351 FOT for automotive gigabit connectivity

KDPOF significantly lowers costs for the new KD9351 by constructing the transimpedance amplifier, photodiode, LED driver, and LED as one single device. Additional benefits are a shorter supply chain and no test duplication with the final test at the Tier1. Furthermore, the assembly of the FOT and the existing KD1053 IC is simplified and the connector offers snap-fit without soldering. The KD9351 reuses low-cost MEMs encapsulation and allows SMD reflow assembly with 8 by 7 mm LGA components. It is fully shielded against electromagnetic radiation. Fiber connection is done with a very simple plastic connector placed on top. The temperature range, from -40 °C to +105 °C, conforms with harsh automotive environmental requirements. The FOT withstands motor conditions with a vibration class of V2. Additionally, the device endures water without sealing. EMC performance is excellent even with the ECU shield case removed, as shielding is integrated into the PCB component. Optics implement Tx and Rx lenses. Samples are already available.

KDPOF presents the brand new integrated Fiber Optic Transceiver (FOT) KD7051. It is the first device for optical in-vehicle connectivity that incorporates the transceiver IC, optoelectronics, and optics. The integrated FOT is a 100 Mb/s optical port in one single component. “By constructing the ASIC IC, photodiode and LED as one single device, we significantly reduce cost and footprint for automotive Ethernet connectivity at 100 Mb/s,” stated Carlos Pardo, CEO and Co-Founder of KDPOF. “The decreased number of parts also reduces the effort in testing and qualification.”

Cost and Size Reduction by Integrating Transceiver IC, Optoelectronics, and Optics into One Fiber Optic Transceiver

KDPOF’s new KD7051 thus substantially reduces the overall expense compared to STP (shielded twisted pair of copper wires). Further advantages are no margin stacking between links in the supply chain and supply chain simplification. Consequently, it offers competitive pricing for EMC critical or galvanic isolated critical links. Applications include battery management systems, camera and sensor links, fast Ethernet links and smart antenna links.

Simple Implementation

As a plastic optical fiber with a large diameter, POF is more cost-effective to manufacture and install: installation is just easy plug and play; winding and clamping is similar to copper cables. Moreover, during the car assembly, the optical harness can be installed in the same process as the copper harness. POF has been present in vehicles for more than 10 years and is installed in millions of cars.
