As a national high-tech enterprise certified with IATF 16949 and ISO 9001, Dongguan Jihongfa New Energy Technology Co., Ltd. specializes in precision connector solutions. Our SFF-8611 8X Female Connector is engineered to meet the rigorous demands of modern data centers and enterprise storage systems. Compliant with the SFF-8611 specification, this connector serves as a critical interface for SAS (Serial Attached SCSI) and SATA (Serial ATA) protocols, facilitating high-speed Data Transmission between server backplanes and storage drives. Designed for reliability, Signal Integrity, and seamless integration, it is a cornerstone component for building robust and scalable data infrastructure.
Built by a trusted supplier to industry leaders, our connector embodies the precision and quality that Jihongfa delivers across its product range, from SATA and SAS to USB 3.0 and board-to-board solutions. This 8X female connector is tAIlored for applications where data throughput and connection stability are non-negotiable.
The SFF-8611 8X Female Connector is a standardized interface component defined by the SFF (Small Form Factor) committee. The "8X" denotes its configuration supporting eight data lanes, which is commonly used for dual-port SAS 3.0 (12 Gb/s per lane) or SATA III (6 Gb/s) connections. This female connector is typically mounted on a server backplane or host adapter card, mating with a corresponding male connector on a hard drive or SSD tray. It is designed to support both SAS and SATA protocols, offering flexibility in storage configuration.
Jihongfa manufactures this connector with a focus on the stringent requirements of server and data storage environments, ensuring Compatibility, durability, and performance that IT hardware OEMs and system integrators can depend on.
1. High-Performance Signal Integrity
Optimized for High-Speed Data: Designed to support SAS 3.0 (12 Gb/s) and SATA III (6 Gb/s) data rates with minimal signal loss and crosstalk, ensuring reliable data transfer.
Robust Contact Design: Features precision-machined contacts with reliable plating (often gold over nickel) for low insertion force, stable electrical connection, and corrosion resistance.
Impedance Controlled: Engineered to maintain controlled impedance across the data lanes, critical for preserving signal quality at high frequencies.
2. Durable & Reliable Construction
High-Quality Materials: Constructed from high-temperature, flame-retardant plastics (e.g., LCP) and durable metal shields to withstand the thermal and mechanical stresses of server environments.
Secure Mating Mechanism: Incorporates a positive latching system to ensure a secure connection, preventing accidental disconnection due to vibration or movement.

Q1: What is the difference between SFF-8611 and SFF-8643?
A: SFF-8611 is primarily used for internal backplane-to-drive connections supporting SAS/SATA. SFF-8643 (Mini SAS HD) is typically used as an external cable connector or internal cable-to-board connector, also supporting higher SAS speeds.
Q2: Is this connector compatible with both SAS and SATA hard drives?
A: Yes, the SFF-8611 8X connector is designed to be mechanically and electrically compatible with both SAS and SATA protocols, providing design flexibility.
Q3: What does "8X" mean in the product name?
A: "8X" refers to the connector having eight data lanes. This configuration supports a dual-port SAS connection (each port using 4 lanes) or other high-bandwidth configurations.
Q4: Can this connector support SAS 4.0 (24 Gb/s)?
A: The standard SFF-8611 connector is commonly associated with SAS 3.0 (12 Gb/s). For SAS 4.0 speeds, newer standards like SFF-8654 (Mini SAS HD 8i) are typically used. Please verify the specific product specifications for supported data rates.
Q5: What is the mating cycle life of this connector?
A: High-quality SFF-8611 connectors are typically rated for 50 or more mating cycles. Please consult Jihongfa's detailed datasheet for the exact specification.
Q6: Do you offer custom cable assemblies with this connector?
A: Yes, as a company with extensive wire harness operations, Jihongfa can provide custom cable assemblies integrating the SFF-8611 connector based on your requirements.
