# GE 1000Base-ZX Module Combination (1 Port) (128 MB)

This module combination is no longer supported because the line module has reached end-of-life. However, the I/O module is still supported.

> Line module label | GE/FE
> I/O module label | GE I/O SFP
> Number of I/O ports | 1 active, 1 redundant
> Software release | First supported: 2.0.0 Final supported: 5.2.x
> Description | 130 W Gigabit Ethernet The GE SFP I/O module uses a range of small form-factor pluggable (SFP) transceivers to support different modes and cable lengths. The transceivers on this GE I/O module are 1000Base-ZX compliant.
