Unlike most competing single module solutions that provide FC aggregation, the FC4-T aggregates up to three FC client services—either 2G or 4G—rather than two for greater utilization of available bandwidth and lower overall solutions costs. The module also features a system controller function…

…out of alignment.  This timing misalignment originates at the core of what coherent technology is all about – optical phase modulation. Phase modulation is a way of applying intelligence to an optical wavelength so that more data can be transmitted without the need to increase the rate at…

…small amount of energy to control a source of a larger amount of energy. Amplitude Modulation (AM) A form of modulation in which the amplitude of a carrier wave is varied in direct proportion to that of a modulating signal. Asynchronous Replication A replication technique in which data must be committed…

…alone, or with other transport modules for up to 60 Gb/s payload capacity. The modules can also be used in conjunction with Ciena’s F10-A 10G Aggregator Module to further groom services onto 10 Gb/s wavelengths for even greater wavelength efficiency. The M6S module is equipped with six full-duplex…

…module with transport up to 40 km. The 2RS can be used in conjunction with the G6S, carrying both STP and non-STP ISC links to support mixed legacy GDPS and STP environments—referred to as a Coordinated Timing Network (CTN) by IBM. As more environments are transitioned to STP, the 2RS modules…

…Service Modules, CN 4200 is the industry?s only packet optical networking solution with fully integrated Layer 0 C/DWDM transport, Layer 1 OTN switching and sub-wavelength grooming, and Layer 2 Ethernet aggregation and switching – all on a single platform. Each G10/G10X Ethernet Service Module provides…

…management on each add channel * Provisioning (module level) * Alarm and fault reporting * Maintenance and diagnostics Unlike passive filters that rely on the installation of external attenuators to accomplish wavelength power balancing, the VMUX-4 and VMUX-8 modules provide the 4200 with the ability to automatically…

…Ciena has integrated digital signal processing in the transmitter (Tx DSP).  The use of Tx DSP allows sophisticated software-programmable modulation (more on that in the next section). * Soft FEC – A new soft-decision forward error correction (soft FEC) algorithm in WaveLogic 3 significantly…

…;both of which can support antennas sized up to 10 feet. This feature combination enables link lengths beyond 50 km/30 mi. In addition, its dynamic modulation allows a link to be engineered to the highest availability, while maximizing throughput in good weather conditions. Network Protection Using Rapid…
