Good (cheap) 2000Mb/s solution?
I need a good, cheap (its temporary) solution to run 2000mb/s over a single pair of multimode fiber (SX handoffs). I'd ideally like to put in two GEs, and get two out. I could use 10G gear, or OC48 gear, but I was hoping for something less pricey since this only has two run about 200ft between two buildings. Any suggestions? I will be glad to summarize for anyone who wants it. Thanks, Deepak Jain AiNET

I've heard of people who use a pair of SX gbics (1310nm), and a pair of LX gbics (1550nm), and a cheap WDM splitter to get two GigE's down one pair of fiber.

That's exactly the sort of solution I was hoping for. Any suggestions on cheap WDM splitters? Thanks, Deepak

Dunno about internationally, but in the UK I've seen these for sale by RS - Goto rswww.com and search for partnumber 300-8372. They appear to be made by AMP, so I'm sure they can be sourced locally. (Looking at that product also corrects me to 850nm for SX and 1310 for LX) Simon -- Simon Lockhart | Tel: +44 (0)1628 407720 (x37720) | Si fractum Technology Manager | Fax: +44 (0)1628 407701 (x37701) | non sit, noli BBC Internet Services | Email: Simon.Lockhart@bbc.co.uk | id reficere BBC Technology, Maiden House, Vanwall Road, Maidenhead.

Good idea, I'm gonna try that... :) For scaling past that, Cisco makes CWDM GBICs that operate in existing gear, where you can get 8 wavelengths and run them over a WDM splitter. Alas no one that I know of makes a simple cheap 1U box that does 8xGigE in and 1 fiber pair out. -- Richard A Steenbergen <ras@e-gerbil.net> http://www.e-gerbil.net/ras GPG Key ID: 0xF8B12CBC (7535 7F59 8204 ED1F CC1C 53AF 4C41 5ECA F8B1 2CBC)

Cool, so long as your splitter actually handles 1000BASE-SX (850nm)... launched into multimode...? Hmm. Does that fly? 1000BASE-LX is 1310nm, and some proprietary LR stuff goes into the 1500s. Those GBICs ain't so cheap as SX, but hey. Or maybe you're thinking of 10GBASE-Ex? (Ow! My wallet!) Peter E. Fry

This would be my suggestion too but you dont need any WDM kit as you already are using different wavelengths, its possible to buy whats essentially a 3 way fibre connector and just connect both cards in and your fibre out. I believe these splitters are about $150. Steve

Don't forget to add in the appropriate losses into your link budget if you're going more than a couple hundred feet (not the case with the original post, but worth noting). Theoretical losses for a 50/50 beam splitter would be about 3dB, with about 3dB for the recombiner as well... but if memory serves the actual real-world additional losses when one adds splitters to both ends is about 10dB, which would suggest an additional 2dB of random inefficiency per splitter (quite believeable). Others on the list can attest to success with 90/10 beamsplitters running full-duplex on a single fiber, at least with 100baseFX. Recommend www.netoptics.com as a good, responsive source for splitters/taps. ---Rob
