sfpConfigChannelSpacing
Module: SL-SFP-MIB
OID (symbolic): SL-SFP-MIB::sfpConfigChannelSpacing
OID (numeric): 1.3.6.1.4.1.4515.1.10.1.1.1.21
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: In the case of SFP: This bit field value identifies the densest channel spacing the module is compatible with and the number of channels over which the module may be tuned by user command. If not tunable, the number of channels is entered as 1. The bit fields are: Bits 7..6: Channel Spacing 00: 200 GHz (DWDM) 01: 100 GHz (DWDM) 10: 50 Ghz (DWDM) 11: Reserved Bits 5..0: Number of channels (1 � 63). In the case of XFP: The value of this field is equal to the guaranteed range of laser wavelength (+/- value) from Nominal wavelength. (Wavelength Tol. = value/200 in nm)
What is sfpConfigChannelSpacing?
For DWDM SFPs, a bitfield giving the densest supported channel spacing (200/100/50 GHz) and how many channels the module can be tuned across (1 if not tunable); for XFPs the same field instead encodes the guaranteed laser wavelength tolerance relative to nominal.
