QLE2690 Single-port Enhanced 16GFC Fibre Channel Adapter PCIe 3.0 X8 16Gb QLE2690-SR-CK SR Optical Transceiver FC HBA Original

QLE2690-SR-CK High Performance Dual Port Fiber Optic Network Adapter

product overview

QLE2690-SR-CK is a high-performance dual port fiber optic network adapter designed specifically for enterprise level servers and data centers. It supports 25GbE/10GbE multi rate transmission and uses SFP28 optical module interfaces to provide low latency, high-throughput network connectivity solutions. It is suitable for high bandwidth applications such as virtualization, cloud computing, and storage networks (SAN/NAS).

Key Features

High speed and multi speed support

Dual port design, each port supports 25GbE (compatible with 10GbE/1GbE), matched with existing network architecture through adaptive technology.

Support SR (short distance) multimode fiber transmission (wavelength 850nm), with a transmission distance of up to 100 meters (OM4 fiber).

Low latency and high throughput

Adopting PCIe 3.0 x8 interface, providing a total bandwidth of up to 64Gbps, ensuring smooth operation of data intensive applications.

Hardware acceleration features, such as TCP/UDP checksum offloading and large frame support, reduce CPU load.

Advanced features and compatibility

Support RDMA (RoCEv2) and SCSI offloading to optimize storage network performance.

Compatible with mainstream operating systems (Windows/Linux/VMware) and virtualization platforms (SRIOV, NPAR).

Reliability and Management

All metal heat dissipation shell, supporting stable operation in high-temperature environments.

Remote monitoring and firmware upgrades can be achieved through vendor management tools such as QConvergeConsole.
