Infineon unveils 4-Gigabit fibre channel transceivers

Infineon Technologies today announced a new 4-Gigabit Fibre Channel (4GFC) transceiver in a small form factor pluggable (SFP) module with digital diagnostics.

These intelligent SFP (iSFP) modules, using Infineon’s 850nm and 1310nm VCSEL (Vertical Cavity Surface Emitting Laser) diodes, are said to offer multi-rate capability to allow for use in both Gigabit Ethernet and Fibre Channel (FC) applications.

Infineon’s 4GFC modules offer rate-select auto-negotiation capability from 1x to 2x and 4x FC to ensure backward compatibility with existing Fibre-Channel-based equipment, providing system designers with an easy migration path to next generation standards for Storage Area Network (SAN) applications.

According to Infineon, the new high-speed modules provide multi-rate compliance and high EMI and jitter margins for applications like Fibre Channel Fabric and Director Switches, Host Bus Adaptors (HBA) and Redundant Array of Independent Disk (RAID) systems.

Fully compliant with the Small Form-factor Pluggable (SFP) multi-source agreement (MSA), the 4GFC iSFP modules provide an enhanced digital diagnostics monitoring interface, based on the SFF-8472 specification for real-time access to such operating parameters as laser bias current, transmitted optical power, received optical power, internal transceiver temperature and supply voltage. The iSFP modules also feature an advanced release mechanism for ease of pluggability.

Infineon is currently shipping sample quantities of the 850nm VCSEL-based modules with mass production expected by mid-year 2004 and 1310nm VCSEL-based transceiver samples scheduled for Spring 2004.
