X2 Transceiver Specifications
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-19 lists the 10-Gigabit/Ethernet X2 transceiver module available through Cisco.
Table B-20 lists the port cabling specifications for the 10-Gigabit X2 transceiver modules. Table B-21
lists the X2 transceiver optical transmit and receive specifications.
