General fiber properties

This table describes various general properties of the optical fiber connected between the sites.

Table 1. General fiber properties
Property	Platform	Description	Available options	Default
Name	NCS 2000 NCS 1010 NCS 1001	By default, the name of the fiber is based on the number of fibers between the source and destination sites. You can edit the name.	Ã¢â‚¬â€	Ã¢â‚¬â€
Source	NCS 2000 NCS 1010 NCS 1001	Displays the source site name. This field is noneditable.	Ã¢â‚¬â€	Ã¢â‚¬â€
Destination	NCS 2000 NCS 1010 NCS 1001	Displays the destination site name. This field is noneditable.	Ã¢â‚¬â€	Ã¢â‚¬â€
Bidirectional	NCS 2000 NCS 1010 NCS 1001	Indicates whether a standard single fiber is used to transmit the data in both directions.	Ã¢â‚¬â€	Ã¢â‚¬â€
Fiber Type	NCS 2000	Select the fiber type. supports the following fibers, and the default fiber type is .	G652-SMF G652-SMF-28E True Wave Reach True Wave RS True-Wave Plus True-Wave Minus True-Wave Classic Free-Light Tera-Light Metro-Core ELEAF NDSF ALLWave SMF-28 ULL SMF28-Ultra	G652-SMF
	NCS 1010	Select the fiber type.	G652-SMF G652-SMF-28E True Wave Reach True Wave RS True-Wave Plus True-Wave Minus True-Wave Classic Free-Light Tera-Light Metro-Core ELEAF NDSF ALLWave SMF-28 ULL SMF28-Ultra	G652-SMF
	NCS 1001	Select the fiber type.	G652-SMF G652-SMF-28E True Wave Reach True Wave RS Free-Light Tera-Light ELEAF
Length	NCS 2000 NCS 1010 NCS 1001	Displays the span length of the fiber connecting a source and destination site. If necessary, change the span length manually. The Cisco ONP tool automatically updates the fiber length to 1 km or 1 mile. If you change the fiber length, then the tool updates the same in the network tree and the map accordingly. In the network tree pane, expand Fiber and select the fiber couple, A-Z and Z-A. The properties pane displays the fiber couple name, source side, destination side, its span length, loss, and, Polarization Mode Dispersion (PMD) value. You can enter the different span length and loss values for the individual fibers in a fiber couple.	Ã¢â‚¬â€	Ã¢â‚¬â€
Network status	NCS 2000 NCS 1010 NCS 1001	Displays the status of the network, whether the network is being deployed or not. If the network is not deployed, it shows the status as UNDISCOVERED.	Ã¢â‚¬â€	Ã¢â‚¬â€
Business status	NCS 2000 NCS 1010 NCS 1001	Displays the status of the fiber in a business perspective view. If fiber is not deployed, it shows the status as FUTURE. This field is noneditable.	Ã¢â‚¬â€	Ã¢â‚¬â€
Measurement Units	NCS 2000 NCS 1010 NCS 1001	Choose the measurement unit .You can set the measurement unit only for the duct, but not for the fiber pair (couple) or fiber.	Km Miles	Km
Ageing Loss [dB]	NCS 2000 NCS 1010 NCS 1001	Enter the aging loss value for the fiber.	Ã¢â‚¬â€	0Ã¢â‚¬â€When Enable Special Settings is disabled. 3Ã¢â‚¬â€When Enable Special Settings is enabled.
DCN Extension	NCS 2000 NCS 1010 NCS 1001	Check this check box to enable the default use of data connection network (DCN) extension on each span in the project. This setting implies that the optical service channel (OSC) channel is not used to connect the two nodes.	Ã¢â‚¬â€	Ã¢â‚¬â€
OSC FrameType	NCS 2000	Choose the OSC frame type. When set in Auto, Cisco ONP uses FE Frame as the preferred frame type.	Auto OC3 Frame GE Frame FE Frame	Auto
Ageing Factor	NCS 2000 NCS 1010 NCS 1001	Enter the number to fiber aging factor.	Ã¢â‚¬â€	Ã¢â‚¬â€
