I can personally recommend SmartOptics. A norwegian company selling transeivers with cisco blueprint at low cost. http://www.smartoptics.com/
List price SFP, 1.25 Gbps Gigabit Ethernet, 1310nm, SM/MM, DDM, 20dB, 40km $533 compared to Cisco's $3995 for their ZX In the end their cisco/smartoptics/finisar is probably made on the same factory, so it's only a matter of company policy. You should though consider Cisco's third party policy before making your decision, http://www.cisco.com/en/US/prod/prod_warranty09186a00800b5594.html // Ulrich -----Oprindelig meddelelse----- Fra: [email protected] [mailto:[email protected]] På vegne af Nick Hilliard Sendt: 2. oktober 2009 16:06 Til: [email protected] Emne: Re: [c-nsp] Will UDLD work with converters ?

UDLD should be fine - it's just data packets, after all. So unless your media converters are doing something very strange and very wrong, it will be fine. You may want to look at third party optics from reputable manufacturers (e.g. http://www.finisar.com/optical_modules_2), although many organisations have policies in place which work against using third party components. Also, it is very easy to pick up grey optics with cisco serial numbers on them, which means that the special command which we all know about isn't necessary. Also, bear in mind that not all c65k ports support reading DDM info from SFPs. SUP720 cards will, as will later hardware revisions of the 6724sfp blades. Earlier hardware revisions won't. Also, 12.2SX >= SXF9 will not present DDM unless it sees a Cisco serial number.
