Switches
Magnetic & Optical Connectivity Solutions for Ethernet Switches
Modern Ethernet switches—from Layer 2 unmanaged devices to Layer 3 enterprise core switches—depend on reliable magnetic and optical interfaces to ensure network stability. LINK‑PP offers a full portfolio of RJ45 magnetic connectors, LAN magnetics, and optical transceiver integration solutions optimized for switch architectures, including those supporting Power over Ethernet (PoE).
Challenges in Ethernet Switch Interface Design
- Port Density — Many switches integrate 8, 24, or 48 ports, requiring compact RJ45 stacking and space-efficient layout.
- PoE/PoE+/PoE++ Delivery — Switches must handle up to 90W per port (IEEE 802.3bt), necessitating compliant magnetic isolation.
- EMI Performance — Shielded solutions are essential for enterprise-grade electromagnetic compliance (EMC Class B).
- Hybrid Fiber/Ethernet — Uplink ports often require seamless SFP/SFP+ integration for aggregation or uplink.
LINK‑PP Connectivity Solutions for Switches
Shielded RJ45 Magnetic Connectors
Designed for multi-port switches, these connectors integrate isolation transformers and common-mode chokes within a compact shielded housing. They support:
- 10/100/1000Base‑T and 2.5G/5G/10GBase‑T Ethernet
- IEEE 802.3af/at/bt PoE and PoE++ delivery
- Surface-mount (SMD) or through-hole packaging options
- Support for stacking layout in 8–48 port switch panels
High-Frequency LAN Magnetics
Discrete magnetics are deployed between PHY and RJ45 interface to ensure proper signal integrity and EMI suppression. Key capabilities include:
- Insertion loss < 1 dB @ 100 MHz; return loss > 16 dB
- High common-mode rejection (CMRR) for EMI shielding
- 1500Vrms isolation voltage between line and circuit
- Temperature range from –40°C to +85°C for industrial switches
Fiber Uplink: SFP/SFP+ Compatibility
For uplink or aggregation, most switches include SFP cages or embedded transceivers. LINK‑PP provides optical interface compatibility for:
- 1G / 10G SFP/SFP+ slots
- Multimode and single-mode configurations (SR, LR, BiDi)
- Optional cage integration with heatsinks and EMI gaskets
- Temperature range from –40°C to +85°C for industrial switches
Common Use Cases for LINK‑PP in Switches
- Unmanaged industrial switches in factories or edge computing environments
- Managed Layer 3 switches for enterprise and datacenter aggregation
- PoE switches powering IP cameras, access points, or VoIP endpoints
- Fanless embedded switches in smart cities, kiosks, or surveillance boxes
LINK‑PP’s components are trusted in large-volume production switches used across global telecom, surveillance, and industrial automation markets.
