1000BaseLX/LH interfaces are fully comply with the IEEE 802.3z 1000BaseLX standard. However, their higher optical quality allows them to reach 10 km over single-mode fiber (SMF) versus the 5 km specified in the standard. This is where the LH kicks in...which allows them to achieve a longer distance when used with SMF.

I'm trying to get a link up between some non-cisco gear and a provider - the providers show interface is saying "media type is LX". A show interface from a similar link to a different provider gives "media type is LX". Cisco's just showing a single 1000Base-LX/LH GBIC in their docs, so I'm a little confused about where the different media types are coming from. -- matt _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/ _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
