X2 Transceiver Specifications

The Cisco MDS 9134 Switch is compatible with X2 transceivers and cables that have SC connectors. Each transceiver must match the transceiver on the other end of the cable in terms of wavelength, and the cable must not exceed the stipulated cable length for reliable communications.

Use only Cisco X2 transceivers with the Cisco MDS 9134 Switch. Each Cisco X2 transceiver is encoded with model information that enables the switch to verify that the SFP transceiver meets the requirements for the switch.

For information about safety, regulatory, and standards compliance, refer to the Regulatory Compliance and Safety Information for the Cisco MDS 9000 Family.

Table B-19lists the 10-Gigabit/Ethernet X2 transceiver module available through Cisco.
