What Are the Pros and Cons of Fiber-Optic Ethernet?

Optical fiber Ethernet refers to the use of Ethernet LAN data packets running on optical fibers to access the SP network or access in the SP network. The underlying connections can operate at any standard Ethernet speed, including 10 Mbps, 100 Mbps, 1 Gbps, or 10 Gbps, but in this case, these connections must operate at full duplex speed (for example, 10 Mbps in both directions). Fiber Ethernet services can apply the rate limiting capabilities of switches and run at non-standard Ethernet speeds. The fiber link used in fiber Ethernet can be the full bandwidth of the fiber (so-called "dark fiber"), a SONET connection, or DWDM. Fiber Ethernet can operate on a switched LAN basis, although they can interconnect shared LANs.

Fiber-optic Ethernet products can use the Ethernet equipment to implement WAN communication services using the Ethernet packet format. The

The Ethernet-based optical Ethernet metropolitan area network allows operators to provide standard and well-known 10 / 100M bps or 1Gbps Ethernet interfaces, which are the same as the currently convenient interfaces for connecting office networks. Optical backbone Ethernet-based metropolitan area networks will no longer use SONET loops. It will be based on the 10Gbps Ethernet standard currently being completed by the IEEE 802.3ac working group. Its advantages are: One part; Ethernet is a simple and widely popular technology; Ethernet is most suitable for transporting IP transport streams because Ethernet and IP were developed together.

Optical technology enables Ethernet networks to extend beyond longer distances than campus Ethernet. Fiber optic Ethernet running on single-mode fiber enables network links to reach distances of 3 miles to more than 6 miles using 1310nm wavelength technology and 43.4 miles using 1550 nm wavelength technology. ^[1]

The current and planned fiber optic Ethernet devices are based on Layer 2 LAN switches, Layer 3 LAN switches, SONET devices and DWDM. Some companies are planning to launch fiber-optic Ethernet switches designed for network operators. These switches have multiple features to ensure the best possible quality of service (such as packet classification and congestion management).

Dense wavelength division multiplexing is the development direction of fiber optic Ethernet. With the continuous development of fiber-to-the-home projects in China, WDM technology cannot be ignored.

All future products may require the following key technologies and performance: high reliability, high port density, quality of service guarantee, and other functions.
