Applications
Network architects choose the C17-C61 10G DWDM SFP+ 100GHz, 40km ER Industrial, C21 Wavelength for data center interconnect, metro transport and carrier aggregation networks: it runs 10Gbps over SMF and reaches 40km@OS2. With its Duplex LC/UPC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. For networks standardized on Cisco hardware, it is a drop-in equivalent of the DWDM-SFP10G-60.61-I.
Standards and Compatibility
On the compatibility side, this unit is the practical equivalent of the Cisco part DWDM-SFP10G-60.61-I and works in Cisco systems out of the box. Standards compliance covers SFP+ MSA, SFF-8431, SFF 8472, 10GBASE-ER/EW, SDH STM64.
Ordering Information
