8G FC SFP+ Optical Transceiver for Fibre Channel SAN and High-Performance Computing Networks

8G FC SFP+ Optical Transceiver Overview

C-LIGHT 8G FC SFP+ optical transceivers are designed for 8Gb/s Fibre Channel connectivity in storage and high-performance computing environments. The SFP+ form factor provides a compact optical interface for compatible Fibre Channel switches and other network equipment.

The series covers a broad range of optical reaches from 300m to 80km. The portfolio includes an 850nm multimode option for short-distance links, 1310nm single-mode configurations for medium-range connections, and 1550nm single-mode solutions for extended transmission. This range allows the 8G FC platform to address different physical network layouts without limiting deployment to a single optical reach.

8G FC SFP+ Optical Transceiver Key Features

8Gb/s Fibre Channel Performance

Supports data transmission rates up to 8Gb/s for Fibre Channel storage and high-performance networking applications.

Five Transmission Distances

Available reach options include 300m, 10km, 20km, 40km, and 80km for different network deployment requirements.

850nm Multimode Optics

The 300m configuration operates at 850nm over multimode fiber for short-distance equipment interconnection.

1310nm Single-Mode Options

The 10km, 20km, and one 40km configuration use 1310nm optics with single-mode fiber for progressively longer links.

1550nm Long-Reach Optics

1550nm configurations provide 40km and 80km transmission options for extended single-mode fiber connections.

SFP+ Form Factor

The compact SFP+ package supports high-density installation in compatible Fibre Channel networking equipment.

LC Optical Connector

The listed configurations use LC connectors for connection with compatible duplex fiber infrastructure.

Commercial and Industrial Temperature

The product family supports commercial and industrial case-temperature options for different operating conditions.

8G FC SFP+ Optical Transceiver Applications

Fibre Channel SAN

The 8G FC SFP+ is designed for storage area networks where Fibre Channel provides dedicated connectivity between servers, switches, and storage systems.

Fibre Channel Switches

The modules can be deployed in compatible FC switch ports to establish optical links throughout the storage fabric.

Enterprise Storage Infrastructure

8Gb/s Fibre Channel connectivity can be used to link enterprise storage systems with servers and switching equipment.

High-Performance Computing

The product family is also suitable for high-performance computing environments that require reliable high-speed optical interconnects.

Data Center Storage Links

The 300m multimode version can address short optical connections within data center storage environments.

Extended SAN Connectivity

The 20km, 40km, and 80km single-mode configurations can support longer optical paths between storage network locations.

Why Choose C-LIGHT 8G FC SFP+ Optical Transceiver?

Broad Reach Coverage

With five reach classes from 300m to 80km, the product family can accommodate both local storage connections and extended Fibre Channel links.

Multiple Optical Platforms

The combination of 850nm MMF, 1310nm SMF, and 1550nm SMF configurations provides flexibility when selecting optics for different fiber routes.

Dedicated Fibre Channel Focus

The product is positioned for Fibre Channel networks, particularly SAN and high-performance computing environments, rather than being designed only as a general-purpose Ethernet module.

Long-Distance 80km Option

The 1550nm 80km configuration extends the product family into substantially longer optical links where standard short-reach FC modules are not sufficient.

Multi-Vendor Compatibility

C-LIGHT states that the 8G FC SFP+ optical modules are compatible with switches from more than 100 brands.

Quality-Controlled Production

C-LIGHT states that every product passes initial testing, final testing, and factory inspection through a three-step quality-control process.
