Note: Short wavelength (SX) optics are supported. The preferred method of connection for 8 Gb/sec short wavelength (SX) small form factor
pluggable optics (SFPs) is through 50 micron multimode fiber optic cabling rated at 2000 MHz-km (OM3 fiber) or better. Other 50 micron and
62.5 micron multimode fiber may be used as an alternative, but distance limitations exist.

It is anticipated that the tested switches and directors will operate with in service releases of System z operating systems - z/OS, z/VM, z/VSE,
z/TPF, and Linux on System z that support FICON.

Notes:
1.
FCIP distance support is for up to 300 km. Testing was performed with both emulated distance and with real fiber over DWDM.
2.
Performance characteristics can vary depending on environment. Professional assistance should be sought when implementing this technology.
3.
Contact Cisco for further extending FCIP links through use of the FICON XRC Acceleration (XRCA) feature.
4.
Contact Cisco for further extending FCIP links through use of the FICON Tape Acceleration (FTA) for tape writes and reads feature.
