2015Q3 optical network hardware sales fell 10%
11/30/15  |  Industry News  |  FiberOnSale.com

Market research firm IHS Infonetics latest optical networking market research report, the global optical network market in the third quarter reached $ 2.95 billion, from the previous quarter fell 10% year on year over the same period fell 1.7%. Last quarter of the global optical network market has 21% of the chain growth.

CDC-F ROADM technology should be a timely

All-optical switching is the future direction of development, but also from the current development trend, this "future" is not far away. Many in the industry view: ROADM-based networking and scheduling is not sensitive to the rate applicable to ultra-high-speed optical networking and scheduling transmission systems, but also can greatly reduce power consumption and floor room. After years of gradual improvement technology, functionality and performance, CDC-F ROADM (ie colorless and directionless without conflict and supports flexible grid capacity reconfigurable optical forked Multiplexer) device has matured, basically solved the light layer networking encountered many problems. Some foreign operators in the deployment of 100G networks have begun to do large particles using ROADM traffic scheduling, a direct transition to an all-optical network. March 2015, Verizon announced the adoption of Ciena and Cisco's packet optical transport platform Metro 100G deployment, CDC-F ROADM technology for the first time to get a commercial scale. In the same month, Alcatel-Lucent announced that Verizon will use its latest CDC-F ROADM technology to upgrade Verizon's long-haul optical transport network.

Data Center urged 100G optical devices reduce costs
9/18/15  |  Industry News  |  FiberOnSale.com

Optical communication technology in the 2015 forum held recently, Ovum analyst Daryl Inniss speech, analyze the optical communication opportunities in the data center field. He said the data center network is driving demand for high-bandwidth connections between data centers and data center for internal. Terabit-level connection between the data center needs; and internal data centers require more cost connection to 100G. However, the high cost of optical networks market slowdown in the rate of expansion is a fundamental problem.

EPON - Ethernet Passive Optical Network
8/25/15  |  Technical Article  |  FiberOnSale.com

EPON is the best combination of several technology and network structure. EPON uses multipoint structure, passive optical transmission, offers a variety of services over Ethernet. At present, IP/Ethernet applications accounted for more than 95% of the entire LAN communication, EPON since the economic and efficient use of the above-described structure, will become an end-user access network connecting the most efficient communication method.

OADM applications in all-optical networks

OADM equipment in long haul and metro networks are useless.
◆ In the trunk applications, OADM device of choice up and down business intermediate nodes.

Technical characteristics of the active optical network
8/7/15  |  Technical Article  |  FiberOnSale.com

Active optical network central office equipment (CE) and remote equipment (RE) connected via active optical transmission equipment. Transmission technology is the backbone network SDH and PDH technologies have been widely adopted, but the main SDH technology. Remote device mainly to complete the collection business, interface adapter, multiplexing and transmission. Central office equipment mainly to complete the interface adapter, multiplexing and transmission. In addition, the central office equipment to the network element management system also provides network management interface. In the actual construction of the access network, active optical network topology is typically star or ring. Active optical network technology has the following characteristics:

AON - Active Optical Network
8/3/15  |  Technical Article  |  FiberOnSale.com

AON (Active Optical Network) is a signal during transmission, the transmission network from the central office equipment to the use of the photoelectric conversion devices, active optoelectronic devices and fiber optic transmission equipment and other active optical fiber between user allocation unit. Active optical device comprises a light source (laser), optical receivers, optical transceivers, optical amplifiers (fiber amplifiers and semiconductor optical amplifiers).

Optical Access Network
8/2/15  |  Technical Article  |  FiberOnSale.com

Optical Access Network refers to the optical fiber as the transmission medium of the network environment. Technically fiber access network can be divided into two categories: active optical network (AON) and passive optical network (PON). Active optical network can be divided into SDH and PDH's AON; passive optical network can be divided into narrowband and broadband PON.
