Use of Mode Conditioning Patch Cables in Gigabit Ethernet and 10
Gigabit Ethernet Laser-Based Transmissions
Gigabit Ethernet Laser-Based Transmissions
PB530836
This bulletin describes the necessary steps to help ensure that Gigabit and 10 Gigabit Ethernet laser-
based transmissions over multimode fiber (MMF) are successfully implemented and supported. It depicts
the requirements for mode conditioning patch (MCP) cables.
Cisco Transceiver Modules and Mode Conditioning Patch cables
The transceiver modules affected by the requirement of MCP are described in Table 1.
