Key Parameters To Check When Buying A Pluggable Optical Filter

When purchasing a Pluggable Optical Filter, many buyers only focus on price and ignore core performance indicators. If you want a stable fiber optic filter for your FTTH or WDM system, you need to check these parameters of the Pluggable Optical Filter.

First, working wavelength band of the Pluggable Optical Filter. Our mainstream Pluggable Optical Filter passes 1260–1360nm & 1460–1581nm light, and reflects 1610–1660nm. We also provide customized WDM wavelength combinations such as 1310+1550/1625, 1310+1490/1550 for different PON projects.

Second, Insertion Loss (IL) and Optical Return Loss (ORL). High-quality Pluggable Optical Filter keeps transmission insertion loss ≤1.2dB and reflection IL ≤1dB. Higher ORL means better signal stability. Our Pluggable Optical Filter reaches ORL >18dB at 1260~1360nm.

Third, connector type. The Pluggable Optical Filter can be SC/UPC, SC/APC, LC/UPC or LC/APC. SC APC Pluggable Optical Filter is the most common type for FTTH field. Besides, operating temperature range is also important: our plug-in optical filter works well between -40℃ and +85℃, fit for outdoor cabinets.

Before bulk order of the Pluggable Optical Filter, confirm wavelength requirement, connector face and loss index with your supplier. Good parameters guarantee long-time stable running of your optical network.
