Our Popular Product

External WiFi Antenna 2.4GHz/5GHz Rubber Duck SMA Swivel Antenna

This external rubber duck antenna is designed for reliable wireless signal transmission in routers, IoT devices, gateways, GSM/LTE modules, and WiFi equipment. The antenna features a durable rubber-coated housing over a flexible internal element, providing good mechanical resistance against bending and everyday handling. It is built with a 90-degree hinged/swivel joint at the base, allowing the antenna to rotate and fold flat for flexible mounting and space-saving installation. Two connection options are available: a direct SMA male screw-type connector for external panel mounting, or a thin coaxial pigtail cable terminated with a U.FL/IPEX connector for internal PCB-level mounting. The antenna body is finished in matte black for a clean, professional look. Customization is available on frequency range, cable length, connector type, and gain upon request. Suitable for OEM/ODM electronics manufacturers and volume orders.

Fiber Optic Patch Cord ST/FC/LC UPC APC Singlemode Multimode Cable

This fiber optic patch cord is designed for reliable, low-loss connections in telecom, data center, FTTH, and enterprise network installations. Available in both singlemode (9/125µm, yellow jacket) and multimode (50/125µm or 62.5/125µm, orange jacket) versions to match different transmission distance and bandwidth requirements. Multiple connector types are offered, including ST, FC, LC UPC (blue), and LC APC (green), in simplex or duplex configurations, allowing flexible matching to existing network hardware. Each cord features a durable PVC or LSZH outer jacket, precision-polished ferrules for low insertion loss, and color-coded connector boots for easy identification. Custom lengths, connector combinations, and cable jacket types (PVC, LSZH, armored) are available for OEM/ODM and bulk orders.  

Battery BMS Signal Communication Wiring Harness Multi-Connector

This wiring harness is designed for signal and communication connections within battery management systems (BMS) in energy storage systems (ESS) and EV battery packs. It features multiple connector types along a braided, abrasion-resistant sleeved cable, with clearly labeled connection points (e.g., B-P17, D-P15) for accurate installation and reduced wiring errors. The harness uses color-coded and twisted-pair wiring for signal integrity, along with heat-shrink tubing for strain relief and moisture protection. Suitable for OEM/ODM battery pack assembly, with customization available on connector type, length, and pin-out configuration.

SFP/SFP+ Cage Connector Stacked Metal Housing 1x4/2x4/2x6 Port

This SFP/SFP+ cage connector is a stamped stainless steel housing designed to hold pluggable optical transceiver modules on network switches, routers, media converters, and other datacom equipment. The cage features integrated EMI shielding fingers, a heat-dissipation perforated top surface, and press-fit or through-hole solder tails for secure PCB mounting. Multiple port configurations are available, including single-row and stacked 2-row designs (4, 6, 8, and 12 ports), to match different port density requirements on line cards and pluggable I/O panels. The rugged metal construction meets standard SFP MSA mechanical specifications for reliable insertion/extraction cycles. Custom port counts, plating (nickel or tin), and light pipe compatibility are available for OEM/ODM orders.

RJ45 Ethernet Jack with Integrated Dual USB 3.0 Combo Connector

This combo connector integrates a shielded RJ45 Ethernet jack with two stacked USB 3.0 Type-A ports into a single compact metal housing, commonly used on routers, set-top boxes, industrial PCs, and networking equipment where panel space is limited. The RJ45 port includes standard LED indicator windows for link/activity status, while the USB ports feature blue internal inserts consistent with USB 3.0 SuperSpeed signaling. The full metal shielded housing provides strong EMI protection and ESD grounding, with through-hole solder tails for stable PCB mounting. Custom port arrangement, LED color, and USB version (2.0/3.0) are available for OEM/ODM orders.

LAN Ethernet Magnetics Module Network Isolation Transformer 16/20 Pin

This LAN magnetics module provides signal isolation and impedance matching for Ethernet network interfaces in switches, routers, network cards, and other datacom equipment. Each module is fully epoxy-encapsulated for mechanical protection and electrical insulation, with through-hole pin arrays for direct PCB mounting. Multiple package sizes and pin counts are available, including compact single-port modules and larger multi-port designs, to support 10/100/1000 Mbps Ethernet applications. The module integrates the transformer, common-mode choke, and related passive components into a single package, simplifying PCB layout and reducing component count compared to discrete magnetics designs. Custom pin configuration, package size, and electrical specification (insertion loss, return loss, isolation voltage) are available for OEM/ODM orders.
