The 4 Channel 200GHz WDM Filter for Fiber Networks represents a high-performance wavelength division multiplexing solution engineered to optimize fiber bandwidth utilization in modern communication networks. This passive optical component utilizes advanced thin-film filter (TFF) technology to combine or separate four distinct optical signals onto a single fiber, each spaced 200GHz apart (approximately 1.6nm at 1550nm wavelength) .

Designed for operation in the C-band (1530nm-1565nm), this WDM filter enables simultaneous transmission of multiple data streams over a single fiber pair, effectively quadrupling network capacity without additional fiber deployment. The component features a compact, epoxy-free optical path design that ensures exceptional stability across environmental variations, making it suitable for both metro and long-haul applications .
With low insertion loss and high channel isolation, the filter maintains signal integrity even in high-density wavelength environments. It supports data rates up to 100Gbps per channel, compatible with modern coherent and non-coherent transmission systems. The device meets Telcordia GR-1209 and GR-1221 standards, guaranteeing reliable performance in carrier-grade network deployments .

Enables cost-effective bandwidth expansion by aggregating multiple 10G/40G/100G services onto existing fiber infrastructure. Ideal for connecting data centers and enterprise campuses across metropolitan regions.
Used in long-haul transmission systems to maximize fiber utilization between central offices. The 200GHz spacing supports dense wavelength packing while maintaining sufficient guard bands for system stability.
Facilitates high-capacity connectivity between geographically distributed data centers, supporting cloud services and disaster recovery systems. Enables 400Gbps aggregate bandwidth over a single fiber pair when using 100Gbps per channel.
Critical for mobile backhaul applications, aggregating multiple 5G cell site connections onto fiber links. Supports the low latency and high bandwidth requirements of 5G NR (New Radio) deployments.
Allows simultaneous transmission of video, voice, and data services over shared fiber infrastructure. The high isolation prevents interference between analog video and digital data channels.
200GHz filters provide 1.6nm channel spacing (at 1550nm), while 100GHz filters offer 0.8nm spacing. 200GHz systems are more cost-effective and tolerant of wavelength drift, making them suitable for metro and enterprise networks. 100GHz systems provide higher density for long-haul networks where fiber is scarce .
Yes, this bidirectional filter can function as both a mux (combining multiple wavelengths onto one fiber) and a demux (separating combined wavelengths into individual channels). The symmetrical design ensures consistent performance in either mode.
The filter maintains stable performance across its operating range with wavelength temperature shifting <0.002nm/°C and insertion loss variation <0.005dB/°C. This minimizes the need for active temperature control in most deployment scenarios .
The filter is designed for use with single-mode fiber (SMF-28 or equivalent) operating in the C-band (1530-1565nm). It is not compatible with multimode fiber due to mode field diameter mismatch and higher insertion loss.
Use compressed air cans to remove loose debris, followed by alcohol-moistened lint-free wipes for connector endfaces. For bulkhead ports, use dedicated push-style cleaning tools. Inspect connectors with a fiber scope (≥200x magnification) before mating to ensure cleanliness.
