I was planning to upgrade a 400m single mode fiber link from 1 gbe to 10 gbe using HP3800-24g-2SFP+ switches and HP X132 10G SFP+ LC LR Transceivers (J9151A). I am trying to verify that our existing SMF cable should be compatible.
Existing SMF which is Corning Optic Freedm (datasheet attached) with jacket legends: "12 SM FREEDM OFNR (ETL) OFN FT4 (CSA)" . Datasheet attached. Its states "SERIAL 10 Gigabit Ethernet - 10000 m - 40000 m" which appears to be a maximum distance range.
I note that HP's quick spec shows
Low metal content, single-mode fiber-optic, complying with ITU-T G.652
and ISO/IEC 793-2 Type B1;
• 2m-10km with 9/125 μm single-mode cable
Cable length 2m to 10km
Fiber type Single Mode
I can't tell if the "9/125 μm single-mode cable" applies to the maximum distance or to its basic operability.
Cisco's 10GBASE SFP+ Modules datasheet for for its equivalent Cisco SFP-10G-LR states:
"The Cisco 10GBASE-LR Module supports a link length of 10 kilometers on standard single-mode fiber (SMF,G.652)." No caveat on SMF core diameter.
I believe this fiber to be "standard SMF" and its datasheet (attached) states its compliance with ITU-T G.652. It also states its core diameter of 8.2 μm.
Am I overthinking this? I would just like to believe I will succeed before I cough up $4k for a pair of these transceivers.
