Talk:Multi-mode optical fiber

From Wikipedia, the free encyclopedia

The 400MB/s FC-AL standard offers 2Gbps over 70m of multimode fiber (62.5µm) according to Fibre Channel. Additionally, there are two popular types of multimode fiber: 62.5µm and 50µm. These measures indicate the size of the fiber's core. These two core sizes have slightly different attenuation properties and generally should not be mixed (which causes greater attenuation). Both sizes of multimode fiber are recognized in the standards for Ethernet (IEEE 802.3), Fibre Channel, ATM, FDDI, and Token Ring (among others).—Preceding unsigned comment added by 208.20.220.72 (talk • contribs) 10:40, February 1, 2006

The Fiber Optics LAN Section has updated the section on multimode fiber to help ensure that it reflects the current capabilities of the medium. We are concerned that based on the previous information provided, readers would believe that multimode fiber had transmission capabilities of only 1 Gb/s, when in fact, there are grades of multimode fiber now that easily support 10 Gb/s and beyond. The page made no reference to the development of fiber types such as Laser optimized multimode fiber, which enables multimode fiber to be used with Vertical Cavity Surface Emitting Lasers (VCSELs) among other omissions.—Preceding unsigned comment added by Lizgo (talk • contribs) 12:43, July 13, 2007

[edit] Market analysis

The references about the market analysis thing need removing and putting in a footnote :) Arghlookamonkey 20:22, 28 October 2007 (UTC)

I have removed the following text, as not properly cited. If a published source (online or print) can be provided, the material can be reinstated. A link to the website of the market researcher is not sufficient, unless the claims in this paragraph can be found there. If so, a link directly to the page containing the relevant material would be required.

According to research conducted by Matthew O. Burroughs (www.marketsharetrends.com) the predominant multi-mode fiber deployed today is still legacy 62.5/125 µm multi-mode fiber, although 50/125 µm fiber, including all bandwidths, is expected to surpass 62.5/125 µm by the end of 2007. Of the 50/125 µm fiber being deployed today, slightly more than half is...

Also note that the reference to "today" is inappropriate for an encyclopedia, and the "expected to surpass" claim violates the crystal ball policy.--Srleffler 20:43, 28 October 2007 (UTC)
