Passive WDM 25G CPRI Transceivers SFP28 CWDM 1270-1370NM 40KM SMF Dual LC

Passive WDM is a low-cost and no power required network solution enabling the access of multiple network services over existing optical fiber and saving fiber resources. The mainstream scenario of Passive WDM includes Coarse Wavelength Division Multiplexing (CWDM) and Dense Wavelength Division Multiplexing (DWDM). 
 

CWDM scenario uses up to 18 independent wavelength from 1270nm to 1610nm, in an interval of 20nm, according to ITU-T G.694.2 Standard. It is more cost effective, easy to deploy,  than DWDM 

Top-Trans TCM-SFP28-ER-XX transceivers is designed for 5G Fronthaul with Passive CWDM System. It uses the light wavelength ranged between 1271nm and 1371nm to create the fiber link up to 10KM via dual SMF. It is fully compliant with 25G SFP28 CWDM MSA and CPRI/eCPRI standard, using CWDM DFB and PIN Receivers. It supports the protocol of CRRI Option 10 (24.33 Gbps), CPRI Option 9 (12.165 Gbps), CPRI Option 8 (10.138 Gbps), CPRI Option 7 (9.830 Gbps).
