Chapter 1 Product Overview Supported Transceivers Send document comments to [email protected] Note The maximum length of fiber optic runs is limited to 300 meters. This is imposed by our use of 802.3X/802.1Qbb Priority Pauses. SFP-10G-LR is supported between fabric interconnect and I/O Module, but the 300m limit still applies. SFP Transceivers The SFP 1 -Gigabit Ethernet transceiver module is a bidirectional device with a transmitter and receiver in the same physical package. Table 1-6 lists the supported SFP optical transceivers. Table 1-7 Supported SFP Optical Transceivers Model GLC-T GLC-SX-MM GLC-LH-SM Description 1-Gigabit Ethernet copper SFP module 1-Gigabit Ethernet-short range (550m max) SFP module 1-Gigabit Ethernet-long range (10km) SFP module Note The maximum length of fiber optic runs is limited to 300 meters. This is imposed by our use of 802.3X/802.1Qbb Priority Pauses. SFP-10G-LR is supported between fabric interconnect and I/O Module, but the 300m limit still applies. SFP+ Copper Cables Copper cables are available for use with the 10-Gigabit Ethernet SFP+ module. See Table 1-8 for a description of these cables.
