[2007-01-29] Many thanks to Edward Beili, for providing an excellent Wikipedia article about EFM. [2006-11-02] Another LightReading Webinar on the latest in EFM: “Ethernet in the First Mile: Technology & Market Update”. [2006-09-15] IEEE-SA Standards Board has approved the 10GEPON (XEPON) PAR. The name of the new task force is P802.3av. [2006-03-10] IEEE takes on the next challenge in EPON: a Study Group will prepare the ground for a 10 Gb/s version of EPON (=XEPON?); more info on http://xepon.ethernetinthefirstmile.com. [2006-03-08] IEEE Standards Press has released a new book on EFM: “Ethernet in the First Mile: Access for Everyone” by Wael Diab and Howard Frazier. Also available at Amazon. [2005-09-01] LightReading Insider publishes “Ethernet in the First Mile: Who’s Doing What?”. Quote from the abstract: “This report examines the different forms of Ethernet access defined by 802.3ah. It provides a product taxonomy of the EFM space, splitting vendors into their respective categories and detailing the various niche vendors targeting 802.3ah and similar EFM technologies. It also describes the positions of some of the large, established telecom equipment vendors as regards 802.3ah. In closing, the report discusses the potential for future development of EFM technology and provides some further analysis of the general state and current direction of the EFM market.” [2005-08-08] LightReading is organizing another Webinar on Ethernet in the First Mile. It will take place on Wednesday, August 17, 2005 (2:00 p.m. New York / 7:00 p.m. London). You can sign up through the LightReading website. [2005-03-02] Ethernet rules for the first mile, an article in Total Telecom's recent Next Gen Ethernet Supplement, covers Ethernet in the First Mile. Read the article here: PART 1 and PART 2. [2005-01-31] An interesting update of the EFM equipment market by Ed Gubbins from Telephony Online can be found at: http://telephonyonline.com/mag/telecom_ahha/.

General QuestionsWhat is “Ethernet in the First Mile”? What is the EFM standard about? Where can I get a copy of the EFM standard? Where can I order an EFM service subscription? Where can I buy EFM equipment? Where can I get more information on EFM and related standards? To whom can I turn if I still have questions about EFM or related standards? Whom can I notify if I find an error in the EFM standard? EFM Copper Related QuestionsWhat is “bonding” or “PME Aggregation”? Is 10PASS-TS limited to 10 Mb/s? Is 2BASE-TL limited to 2 Mb/s? Is EFM Copper the same thing as Ethernet over xDSL? Does EFM Copper use HDLC encapsulation? Point-to-Point Fiber Related QuestionsWhat is new about EFM over point-to-point fiber? EPON Related QuestionsWhat is a Passive Optical Network? What is the purpose of the LLID in EPON? What is the equivalent in GPON? OAM Related QuestionsHow is EFM OAM different from IEEE 802.1ag? How is EFM OAM different from SNMP? Why can EFM OAM only be used to read MIB variables, and not to write them? |
