TL;DR — Once a board needs several Ethernet ports, you switch from single RJ45 sockets to a multi-port jack (母座): many 8P8C sockets in one housing.
- Ganged (1×N) → one row, 1×1 to 1×8
- Stacked (2×N) → two rows in one body, 2×1 to 2×8 · ~halves the board-edge length vs two 1×N strips
Per-array options (VOOHU matrix):
- Mount angle: 45°, 90° (vertical), 180° (right-angle)
- Magnetics: integrated magjack or discrete
- Data rate: 10/100M → 10GBASE-T (+SPD), mixable per port
- PoE: non-PoE → 1.5 A per contact (covers IEEE 802.3bt Type 4)
- Per-port status LEDs · DIP or SMT · shield tabs · temp grades 0~+70 °C to −40~+105 °C
Every port is still 8P8C (IEC 60603-7, T568A/T568B) — the hard part is dense packing without crosstalk or PoE heat. Shield the housing for Cat6A/10G stacked decks.
