ST-10G-CWDM-XXXX-20
3-year warranty · Standard lead time 3–7 days
10G CWDM SFP+ Optical Transceiver — 20km, 18 Wavelengths 1270–1610nm
The Sate Optics ST-10G-CWDM-XXXX-20 is a 10G CWDM SFP+ optical transceiver for single-mode links up to 20km. Order it on any of the 18 CWDM wavelengths from 1270nm to 1610nm (20nm grid) and pair it with a CWDM mux/demux to run multiple 10G channels over one fiber pair.
Why This Module
-
Any CWDM channel: 1270–1610nm on the 20nm CWDM grid, specified when you order
-
Mux-ready: pairs with CWDM MUX/DEMUX shelves to multiply fiber capacity
-
DDM monitoring: real-time optical power, temperature and voltage readings, 0~70℃ commercial range
-
Compatible with your platform — coded for major networking platforms, including Cisco, Juniper, Arista, Huawei, Nokia, H3C and ZTE; 100% tested before shipment.
