Hi, I want to buy Cisco's gigabit SFPs for a network rollout and I've realised, from the info I've gathered on the website, that there's a leap from the < 10km range (GLC-LH-SM) to the < 70km range (GLC-ZX-SM). The distance I have in mind falls in between 10km and 70km.
What are the implications of using a GLC-ZX-SM module to light a stretch of 20 - 30km? Would I need to add an attenuator, given that 20km is well below the 70km limit? Any info would be helpful. Thanks. _______________________________________________ cisco-nsp mailing list [email protected] https://puck.nether.net/mailman/listinfo/cisco-nsp archive at http://puck.nether.net/pipermail/cisco-nsp/
