AON advantages ■ Higher symmetrical bandwidth capability, which could become an even more significant advantage if demand for P2P and Web 2.0 applications increases rapidly (see 4.2.3). ■ Greater bandwidth scalability. The ability to swap Ethernet line cards in the central office to increase bandwidth capability makes AONs far more flexible than PONs. By virtue […]

What is AON Active optical networks
An active optical network (AON) comprises an active Ethernet switch that acts as the intermediate point between the central office and the end-user. Theoretically, this switch is capable of delivering symmetrical speeds of 100Mbps to 32 users simultaneously. This level of throughput could only be achieved, however, if the link between the remote Ethernet switch […]
Next-generation PONs
The FSAN consortium, through its Next Generation Access (NGA) task group, is exploring different technologies to evolve optical access systems beyond GPON. The two main candidates are 10G PONs and WDM-PONs. 10G PONs enable one wavelength to carry 10Gbps capacity, which is shared in the same way as existing point-to-multipoint PON architectures. WDM-PONs allow multiple […]
Communications Infrastructure – Outside Plant (OSP) Designer
What an OSP Designer required to know: Seeking an experienced Communications Infrastructure OSP designer of a technical mindset that is organized, motivated and a good self-manager. Willingness and ability to dig in and take project responsibility from conceptual stage through construction support stage is a must. Compensation will be based on practical hands-on experience including […]
Inspecting and Unloading Fiber Optic Cables
Trouble-free unloading begins with letting your Fiber Cable Customer Service Representative know of any special packaging or delivery requirements (no shipping dock available, call before delivery, etc.). will make every reasonable effort to comply with your shipping needs. When the shipment arrives, make sure the cable types and quantities match the bill of lading. Contact […]
125Mbps to 2.5Gbps FTTx Burst-Mode Laser Driver/Postamplifier
The PHY2078 is a combined burst-mode laser driver and limiting amplifier for use within fiber optic modules for FTTx applications. Used with the PHY1095 or PHY1097 transimpedance amplifiers and a low cost serial EEPROM, the device forms a complete PON diplexer silicon solution. The transmit block includes a high-frequency modulator and a bias current generator. […]
What you need to know about FTTx OSP Design
Description: This three-day class has been developed with 16 hours of classroom lecture and 8 hours of handson design exercises to teach attendees to apply critical issues such as customer take rate and density to outside plant design. This course covers FTTH network field configurations, design benchmarks, and installation parameters for active Ethernet and PON […]
Fiber Considerations for 100 Gig – 3
Fiber Requirements Point to OM4 OM4 fiber offers a minimum effective modal bandwidth (EMB) of 4700 megahertz kilometer (MHz•km) at 850 nanometers (nm) compared with 2000 MHz•km for OM3. Both OM3 and OM4 fibers are 50 micron (µm) laser-optimized fibers with extended bandwidth and were designed to enhance the system cost benefits enabled by 850 […]
Fiber Considerations for 100 Gig – 2
Network Design and Layout As in previous Ethernet standards, 40 Gb/s and 100 Gb/s define several different Physical layer (PHY) implementations for transmitting information over various distances and media types. These media types include multimode and singlemode optical fiber cabling and some form of copper cabling. Additionally, various transceiver types are defined, distinguished by which […]
Fiber Considerations for 100 Gig – 1
The unrelenting demand for band width in the enterprise, and the resulting need for high-capacity, high-performance computing, is generating ever-faster network speeds. But 100 gigabits per second (Gb/s)? This would have seemed like a pipe dream 10 years ago, but it is now a fact of life in today’s enterprise networks and data centers. What, […]
