Upper and lower alarm thresholds are set for the transmit and receive power of the optical module on the interface. The NCS 1001 provides optical amplification, protection switching, and Optical Time Domain Reflectometer (OTDR) capability in a 1RU system supporting up to three modules. The NCS1K-EDFA supports several configuration options, including 50 GHz, 100 GHz, 75 GHz, and flex-grid channel spacing. SFP: The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for both telecommunication and data communications applications. The SFP can be used to interface some IFMs (see tables below) to fiber (=Optical). The SFP is used up to data rate speed of 1 Gbps.
