This article covers RJ45ケーブルアダプターイーサネットスプリッター.

Overview

The Noenaeni RJ45 1-to-3 Female Splitter Adapter is a compact accessory that splits a single Ethernet cable into three female RJ45 ports. Gold-plated contacts and an internal PCB board help minimize signal loss, and it supports Cat5 through Cat7 cables. Its plug-and-play design requires no drivers, making it an easy way to expand your network without running new cables. Keep in mind that this is a passive splitter, not a network switch. It shares one line among three devices but does not allow simultaneous full-bandwidth communication. It's best suited for scenarios where you want to alternate between devices or simplify cable routing.

Connectivity & Compatibility

Connector type: 1x RJ45 male (input), 3x RJ45 female (output) Supported cable categories: Cat5 / Cat5e / Cat6 / Cat7 Compatible devices: ADSL modems, routers, set-top boxes, smart TVs, network switches, WiFi access points, hubs Important note: This is a passive splitter only. For simultaneous multi-device communication, use a switching hub instead.

Product Info

Release period: Around 2024 (sold on) Price range: Approximately ¥1,800 (available in black and white) Warranty: Standard warranty from Noenaeni (check product page for details) Package contents: 1x RJ45 1-to-3 female splitter adapter * Market position: Entry to mid-range. A cost-effective accessory for small-scale network expansion or temporary cable management where a full switch is overkill.

Best Use Cases

Remote workers with multiple devices: If you alternate between a desktop PC, laptop, and printer on one Ethernet line, this splitter lets you share the cable without buying a switch. Just remember only one device can be active at a time. Cable clutter reduction: Instead of running multiple long Ethernet cables across the room, use one cable and split it near your desk. This keeps your workspace tidy. Budget-conscious users: If you only need to connect 2-3 devices one at a time and don't require simultaneous connectivity, this splitter saves you the cost of a switching hub (typically ¥1,000-3,000). Not for: Anyone needing simultaneous internet access or file sharing across multiple devices, or those who need full gigabit throughput on all ports. In those cases, invest in a proper network switch.

Things to Consider

This adapter lacks switching functionality, so connected devices cannot communicate simultaneously. It's strictly a physical splitter for manual device switching. It does not support Power over Ethernet (PoE), so it cannot power PoE devices. While the gold-plated contacts help maintain signal quality, for long cable runs or environments requiring maximum shielding, pairing this adapter with Cat6a or higher cables is recommended.
