D-TECH GPON SFP

GPON OLT C+++

GPON OLT SFP modules are designed for GPON access networks and support 1.25Gbps upstream and downstream transmission. These modules use 1490nm transmit and 1310nm receive wavelengths with integrated WDM filtering, making them suitable for OLT, FTTH, ISP, and telecom network applications.
