The UGREEN RJ45 1-to-2 Ethernet Splitter Coupler is a compact networking accessory engineered to expand a single wall outlet or long-run Ethernet drop, allowing two independent hardware units to communicate seamlessly over the web. UGREEN manufactures two distinct architectures for this tool: an active 1000Mbps Gigabit powered version and a passive 100Mbps pair-based version. Option A: The Active Gigabit Edition (Model 45311)
- True Dual-Device Gigabit Networking: Unlike older passive adapters, this powered hub splits a single network line into two distinct outputs while maintaining full 1000Mbps Gigabit bandwidth simultaneously on both paths.
- Auxiliary USB Power Core: Outfitted with a 5V Type-C input power terminal (3ft charging cable bundled in-box) that drives an internal micro-switching processor to handle data routing smoothly without dropped frames.
- Aerospace-Grade Thermal Chassis: Encased in a sleek aluminum alloy shell outfitted with anti-oxidation shielded jacks, offering premium thermal dissipation and heavy block shielding against external signal crosstalk.
Option B: The Passive 100Mbps Pair Edition (Model 50923 / CM210)
- Dual-Pack Paired Configuration: This physical adapter must be deployed as a set of two (one adapter at your router/switch to merge two inputs down a single in-wall line, and the second adapter at the opposite end to split the paths back apart)
- Physical Signal Pin Splitting: Utilizes a custom internal layout that splits a single 8-core Ethernet wire into two dedicated 4-core physical pipelines, capping transmission speeds at a steady 100Mbps per hardware terminal.
- Rugged ABS Build Architecture: Injection-molded from highly durable, wear-resistant ABS engineering plastic containing internal thick metal shielding layers to defend copper wire buses against electromagnetic interference (EMI).
