IBM - 44X1976 - IBM 8 Gigabit SFP+ SW Optical Transceiver

The IBM 44X1976 is an 8 Gigabit SFP+ shortwave (SW) optical transceiver designed for Fibre Channel connectivity over multimode fiber. It provides an 8Gb FC optical interface in the compact SFP+ form factor, making it a practical choice for maintaining or expanding existing IBM SAN fabrics and server-to-SAN links in data centers and enterprise environments.

This transceiver is commonly deployed in IBM Fibre Channel infrastructures alongside SWITCH platforms and can also be used to extend connectivity options on compatible IBM NETWORK MODULE and NETWORK ADAPTER configurations where SFP+ optical interfaces are required.

Key Features

Key technical characteristics for IBM 44X1976 deployments in Fibre Channel SAN environments:

• 8Gb Fibre Channel SFP+ optical transceiver interface to support standard 8G FC link speeds in SAN fabrics.
• Shortwave (SW) optics design to enable cost-effective optical links over multimode fiber within data center rows and rooms.
• SFP+ form factor to fit SFP+ cages on compatible IBM Fibre Channel switches and directors for straightforward field replacement.
• Compatible with IBM SAN switching families that accept 8Gb FC SFP+ optics (for example IBM/Brocade-based SAN switches and directors) to maintain consistent optics across the fabric.
• Suitable for IBM server and storage connectivity where 8G FC host bus adapters (HBAs) and SAN ports require SFP+ SW optics to connect to the fabric.
• Hot-pluggable transceiver design to support maintenance and upgrades with minimal disruption when the platform supports live replacement.
• Optical Fibre Channel media type to provide electrical isolation and longer reach than copper DAC in typical SAN topologies.
• Designed for continuous enterprise operation to support 24/7 SAN availability requirements in production environments.

Refurbished Quality and Warranty

This unit is refurbished hardware, cleaned and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished optics are a pragmatic way to extend the lifecycle of installed IBM Fibre Channel environments, reduce electronic waste, and control budgets compared to buying new.

Direct Hardware Supply includes a one-year warranty from the date of purchase (batteries, tape drives and tape libraries include a three-month warranty). Extended warranty options are available on request. We are an international supplier of refurbished IT hardware, shipping worldwide from Denmark.
