IBM 8Gb Fibre Channel SFP Transceiver

This IBM 49Y4123 module provides 8Gb Fibre Channel connectivity in a standard SFP form factor. It uses shortwave optics for multimode fibre links. The transceiver supports HCRP and SPP protocols for storage networking environments.

Shortwave optics for multimode fibre

Shortwave optics limit reach to multimode fibre distances, so buyers needing long-haul single-mode links must choose a different module. The SFP form factor fits compatible switch and HBA ports without requiring additional cabling adapters.

Questions about this item

Will the SFP transceiver need any firmware updates or cleaning over time?

The module is a passive optical component with no firmware; only the LC connector end-faces may require periodic cleaning with a lint-free wipe and isopropyl alcohol.

What thermal or signal limit appears first during continuous 8 Gb/s operation?

The transceiver is rated for standard operating temperatures; sustained line-rate traffic will hit the SFP cage's thermal envelope before any protocol-level bottleneck occurs.
