FWDM 1X4 MUX G-PON 1310/1490 & XGS-PON 1270/1577 &1550/1610nm SC/APC LGX Box

Single channel 3 port FWDM filter, works in FTTH/FTTx optical network PON CATV Mux Low insertion loss High channel isolation Low polarization dependent loss Exceptional reliability and stability

As 5G, IoT, and cloud computing develop rapidly, bandwidth demand grows. PON technologies (GPON, XGS-PON, NG-PON2+PtP) are evolving, with OTDR for network fault diagnosis and maintenance. 4CH WDM enables their coexistence on the same fiber, boosting network bandwidth and flexibility.

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.

With the rapid development of emerging technologies such as 5G and the Internet of Things, the demand for bandwidth is continuously increasing. To meet these demands, Passive Optical Network (PON) technologies are also evolving. GPON, XGS-PON, and NG-PON2 are the main PON technologies currently in use, and they have achieved coexistence on the same fiber through Wavelength Division Multiplexing (WDM) technology, thereby enhancing the network's bandwidth and flexibility.

As emerging technologies like 5G, the Internet of Things (IoT), and cloud computing develop at a fast pace, there is a steady rise in bandwidth demand. To keep up with this demand, Passive Optical Network (PON) technologies are advancing as well. Currently, the primary PON technologies in use include GPON, XGS-PON, and NG-PON2; meanwhile, OTDR (Optical Time Domain Reflectometer) serves as a tool for diagnosing network faults and carrying out maintenance work. By leveraging 4CH WDM (Four-Channel Wavelength Division Multiplexing) technology, these various technologies can coexist on a single fiber—this not only boosts the network’s bandwidth but also improves its flexibility.

Amid the era of digital transformation, the demand for high-speed, reliable, and flexible communication networks has reached an unprecedented level. Passive Optical Networks (PON) have established themselves as a cornerstone of contemporary communication infrastructure, underpinning a diverse array of applications—ranging from residential home broadband to enterprise-grade networks, and extending even further into broader use cases. To address the ever-increasing bandwidth requirements and secure future-proof network rollouts, the integration of 4CH WDM (Four-Channel Wavelength Division Multiplexing) with key technologies including GPON, XGS-PON, NG-PON2, and RF Video delivers a comprehensive solution. This integration not only maximizes fiber optic utilization but also significantly boosts the capabilities of service delivery.
