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 […]
Alcatel-Lucent Claims 300G Record
Also in today’s EMEA regional roundup: Mobily announces new CEO; Huawei’s 5G push in Europe; Telefónica bags La Liga matches. Alcatel-Lucent (NYSE: ALU) is claiming a distance record for subsea data transmission, covering more than 10,000km using 300G technology in a trial at its research lab in Villarceux, France. The trial deployed 300G 8QAM (8 […]
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, […]
Macrobend Detection Using an OTDR
On a transmission network, one cause of insertion loss on a fiber link is macro bending. This is commonly caused by tight installation or handling. As Fiber-to-the-Home (FTTH) networks lead to a significant increase of fiber installation in the last mile, the space constraints become increasingly stringent. This is driving the need for distributions hubs […]
Optical Splitter
In 2012, a leading market and technology analysts announced the Asia Pacific region (APAC) region leads in the consumption of Planar Lightwave Circuit (PLC) splitter compact devices with 68% of the worldwide value, followed by the American region and finally the EMEA region. The increase of mass FTTx PON network deployment dominates the worldwide PLC […]
