This white paper provides an overview of Coarse Wavelenght Division Multiplexing technology, reviews the various Optical Fiber types with best characteristics for CWDM, discusses the advantages of Small Form Pluggable Transceivers (SFPs) and provides Metro Ethernet CWDM application examples.

802.3ah OAM for Carrier-Class Optical Ethernet in the First Mile

The functions, goals and benefits of 802.3ah OAM Ethernet Fiber Access with Network Interface Devices

The IEEE 802.3ah OAM standard has been developed to bring the Operations, Administration and Maintenance (OAM) mechanisms used in traditional carrier networks to effectively maintain and troubleshoot broadband Ethernet networks. This paper addresses fiber in the First Mile and provides an informative overview of the 802.3ah OAM specification and addresses all Ethernet in the First Mile technologies, including Copper and Fiber.
