Between Series Adapter Cables

1. Overview

Between Series Adapter Cables are interconnect solutions that bridge incompatible connectors or protocols across different device series. These cables enable seamless data, power, and signal transmission between systems with varying electrical or physical interfaces. As technology ecosystems diversify, these adapters play a critical role in ensuring interoperability in consumer electronics, industrial automation, and telecommunications infrastructure.

2. Major Types & Functional Classification

Type	Functional Features	Application Examples
USB-A to USB-C	Supports USB 3.1 Gen2 (10Gbps), reversible plug orientation	Laptop to smartphone charging/data transfer
HDMI to DisplayPort	4K@60Hz video conversion, active signal conditioning	Connecting gaming consoles to commercial displays
RJ45 to Fiber Optic	1000BASE-T to 10GBASE-SR conversion	Enterprise network backbone integration
DB9 to USB Serial	RS-232 protocol translation via integrated IC	Legacy industrial machine monitoring systems

3. Structural & Technical Composition

Typical construction includes:

Conductive Core: Oxygen-free copper (OFC) conductors with silver-plated contacts
Insulation: Foamed polyethylene dielectric for reduced capacitance
Shielding: Multi-layer aluminum-mylar foil + braided copper ( 85% coverage)
Connectors: Precision-machined phosphor bronze contacts with 30 " gold plating
Active Components: Signal repeaters (for lengths >5m) and protocol conversion ICs

4. Key Technical Specifications

Parameter	Typical Value	Importance
Insertion Loss	<0.5dB @ 10GHz	Maintains signal integrity in high-speed applications
Impedance Matching	50 5% (RF variants)	Prevents signal reflections in data centers
Voltage Withstanding	1000VAC @ 60s	Safety compliance for industrial environments
Operating Temperature	-40 C to +85 C	Reliability in automotive/industrial scenarios
Mating Cycles	>10,000 cycles (USB-C)	Durability metric for frequent connections

5. Application Domains

Consumer Electronics: Smartphones (Lightning-USB-C), VR headsets (HDMI-DP)
Industrial Automation: PLCs with mixed serial/Ethernet interfaces
Medical Devices: MRI machines interfacing with modern diagnostic displays
Avionics: ARINC 664 to fiber optic conversion in aircraft cockpits

6. Leading Manufacturers & Products

Manufacturer	Product Family	Key Features
Belkin	USB-C 3.1 to USB-A Gen2	Backward compatible, 10Gbps throughput
Amphenol	9116 Series HDMI-DP	8K resolution support with EDID management
TE Connectivity	1-104286-5	IP67-rated industrial Ethernet adapter
