Ethernet Connectivity Solutions
Ethernet connectivity solutions from VOOHU are organized two ways: by the industry your equipment serves and by the interface you are designing. Both paths lead to component-level reference designs that show where RJ45 connectors, LAN transformers, PoE transformers, common mode chokes and protection devices sit on the board, and what to check at each position.
Solutions by industry
Pick the field your device belongs to. Each field page maps the system architecture layer by layer, shows the Ethernet connectivity solutions used at each layer and marks the devices that have a VOOHU reference design.
Industrial Control
PLCs, servo drives, VFDs, HMIs and industrial switches on PROFINET, EtherCAT and fieldbus networks.Data Communication
GPON ONUs, home and enterprise routers, PoE switches and data center equipment.PV & Energy Storage
Battery management systems, PCS inverters, EV chargers and EMS controllers.Security & Surveillance
IP cameras, NVRs, PoE switches and video intercoms.Power Grid
Protection relays, measurement and control units and DTU / FTU terminals for IEC 61850 substation automation.Pro AV
AV over IP, Dante and SMPTE ST 2110 equipment, matrix switchers and LED video walls.Consumer Electronics
Smart TVs, set-top boxes, NAS, docks and smart home gateways.Contact an FAECan’t find the right part or design?Solutions by interface
Designing a specific port or bus? Each interface solution lists the isolation, filtering, protection and connector parts for that circuit, with standard reference circuits where available.
Ethernet
RJ45 or SFP port, LAN transformer, common mode choke and surge protection, from 10/100M to 10G.Single Pair Ethernet (SPE)
SPE connectors, magnetics and PHYs for long-reach links over one twisted pair.CAN Bus
Isolation, common mode filtering and ESD / surge protection for CAN bus nodes.RS-485
Isolated RS-485 with push-pull power, common mode chokes and surge protection.LVDS
Common mode chokes and ESD protection for high-speed LVDS differential links.Isolated SPI
Isolation transformers for isoSPI daisy chains in battery management systems.PoE (Power over Ethernet)
PoE transformers and LAN magnetics for IEEE 802.3af / at / bt PSE and PD designs.Push-Pull Converter
Push-pull transformers for low-power isolated DC-DC supplies on interface boards.Component-level reference designs
VOOHU FAEs compile these illustrative reference designs for typical devices. Each board marks every component position, its function and the VOOHU part numbers available, so you can review selection notes and packages position by position.
Parts behind these solutions
The same part families appear in most of these Ethernet connectivity solutions. VOOHU makes connectors in its own factory in Dongguan and magnetics in its own factory in Mianyang; Ethernet PHY and switch ICs are supplied as an authorized distributor of JLSemi.

From selection to samples
- 01
Choose a starting point
Open the industry or interface that matches your design and check the parts listed for each position.
- 02
Review the reference design
Compare the reference board with your schematic: isolation voltage, turns ratio, package and pin 1 orientation.
- 03
Request samples
Samples are available for evaluation, and selected parts are free of charge. Our FAE team will be glad to confirm the options for your project.
