EtherChannel Distance Limitations

I am running 1k of single mode fiber between a 4503 and a 3550. I am trying to run a 2gig etherchannel between the two, using LX GBIC Modules. Does anyone know if there is a distance limitation for this etherchannel other than the cables capabilities?

Re: EtherChannel Distance Limitations


there is no other limitation to an Etherchannel other than the distance limitations of the physical media. Read below the relevant Q&A from CCO:

Q What are the distance characteristics of Gigabit Ethernet?

A In principle, there is no limit to the size of a Gigabit Ethernet network, in terms of either physical extent or number of nodes. Like Fast Ethernet and the original 10-Mbps Ethernet, Gigabit Ethernet will support a variety of physical media, with different capabilities in terms of maximum link distance. The IEEE 802.3 Higher-Speed Study Group has identified three specific objectives for link distance: A multimode fiber-optic link with a maximum length of 500 meters; a single-mode fiber-optic link with a maximum length of 2 kilometers; and a copper-based link with a maximum length of at least 25 meters. The IEEE is also actively investigating technology that would support link distances of at least 100 meters over Category 5 UTP wiring.
