The 4200 optical layer product suite now comprises the OAF-00-1-C fixed-gain amplifier (21 dB, 35 nm OA) as well as the OAV-0S-U-C variable-gain amplifier (18-23 dB, 35 nm OA). The 4200 OAs amplify the entire C-band DWDM channel plan and accommodate a single optical fiber for uni-directional transmission…

…is provided using four key modules: * Dynamic Wavelength Router (DWR) * Optical Channel Monitor (OCM-8) * Variable Gain (Rx) Amplifier (OAV-VS-U-C) * Fixed Gain (Tx) Amplifier (OAF-BC-B) The nine-port, Wavelength Selectable Switch (WSS)-based DWR module performs the primary multi-degree optical switching…

…over Ciena’s ActivSpan Common Photonic Layer, a compact, low cost and easy-to-engineer line system. It can also be deployed over third-party amplifier chains to protect existing investments. According to Dany Vandromme, director of RENATER, “This trial demonstrates the maturity of Ciena&rsquo…

…regeneration. The OAs are available in fixed- and variable-gain versions. The OAF-BC-HP fixed-gain amplifier provides 14 and 17 dB gain with 20 dBm output, and the OAV-VS-HP variable-gain amplifier provides 25 dB gain with 20 dBm output. Both versions provide: * Ciena’s SmartGain™…

…10G, maximum transmission distance is reduced by 75% at 40G speeds and 90% at 100G speeds.  This results in the need for additional in-line amplifiers or regeneration equipment (which of course adds cost to the network).  Additionally, polarization mode dispersion (or PMD) is increased 4X with…
