1+1 NET-Ready Optical Protection Switch 1+1 Net-Ready Platform Introduction In today’s network, protection switching at optical layer is a subject of great importance to the carriers. As a member of Oplink’s NETReady product family, Oplink’s NET-Ready series protection switches offer various protection schemes against fiber cuts and network failures. (1+1) Protection With (1+1) optical protection, service is protected from link failures, using an optical splitter to bridge the optical signal and dual feed it on diversely routed working and protection fibers. In the event of a single link failure, an optical switch at the receiving end switches to the protection fiber. The NET-Ready protection switch in 1x2 switch configuration provides this type of protection. The same switch fits both point-to-point and dedicated protection switching ring architectures. Multiple Control Modes NET-Ready (1+1) protection switch provides both Manual and Automatic switching mode. In Manual mode, the system switches optical path only based on the commands from user. In the Automatic mode, the system switches based on the power level detected and the preset threshold. Under automatic mode, the system can be set to be Revertive or Non-revertive modes. Under Revertive mode, the system switches back to the working path automatically after the fault condition is cleared. Under Non-revertive mode, the system does not switch back. Programmable Threshold and Hysteresis Features Independent of data rate, format and wavelength Highly configurable to fit network applications Simple, Plug-and-play Installation User-definable thresholds and hysteresis User-selectable revertive and non-revertive modes Latching optical switch Remote configuration through SNMP management interface Front panel LED and remote alarm Alarm and switching threshold and hysteresis are programmable remotely or locally. Remote Management and Alarm NET-Ready (1+1) protection switch provides remote system configuration and management through SNMP. Web GUI and CLI is also provided for user to manage the system locally via Ethernet or craft RS-232 interface respectively. Applications Optical fiber protection for point-to-point transmission in any data format Optical dedicated protection for fiber ring S**** - R02. 2011.07.01 1+1 NET-Ready Optical Protection Switch 1+1 Net-Ready Platform Performance Specification Optical Performance Parameter Value Operation Wavelength range (λ Op) Unit O-, C- or L-band 1x2 Selector (switch) Insertion loss @ 23 °C, λ Op (include 5% tap) < 1.2 dB Wavelength dependent (WDL) < 0.2 dB Temperature dependent loss (TDL, 0~70°C) < 0.2 dB Polarization dependent loss (PDL) < 0.1 dB Return loss (with connector) > 45 dB Channel cross talk > 55 dB <±0.05 dB < 10 (typical = 3) ms > 10 million cycles Insertion Loss (over all λ Op, TOp, and SOP) < 3.6 dB Wavelength dependent loss at a given temperature (WDL) < 0.15 dB Polarization dependent loss < 0.1 dB Directivity > 50 dB Return loss (with connectors) > 45 dB - 30~10 typical dBm <±1.0 dB 0 to 60 °C Repeatability Optical switching time (from electrical trigger to 90% stable optical output) Durability 1x2 Bridge (splitter) Optical input power monitoring range Optical power reading accuracy [1] IL excludes connectors.
