This 32-channel FWDM module integrates CATV 1550nm transmission with PON 1310/1490nm and XGS-PON 1270/1577nm reception for FTTH/FTTX networks. Using TFF technology, it features low insertion loss (≤0.8dB), high isolation (≥30dB), and stable performance in harsh environments (-40°C to 85°C). The 1U rack design with LC/UPC connectors supports hybrid signal transmission. Two models offer reflection isolation of ≥15dB (A) or 20dB (B), suitable for CATV, optical amplifiers, and fiber access systems.
