Passive components

Attenuators

We offer a broad range of fixed attenuators, either as in-line or as pluggable attenuators with different attenuations and various connectors.

Couplers

Couplers are a bidirectional device with three or more fiber ends, combining the signals of two or more input ports into one output port. They can also be referred to as splitter. Fused Biconical Tapering (FBT) refers to a manufacturing process for passive optical network components. It consist of twisting two bare fibers exactly to each other, stretching and then fusing the fibers together also called "tapering".

CUBO’s Fused Couplers are based on the classic technology of fiber fusion. The devices are used to split respectively combine power or can even be made to be wavelength sensitive and to provide a WDM functionality.

Splitters

Planar Lightwave Circuit (PLC) splitters follow a specific manufacturing process for optical passive network components. They consist of a waveguide array that is applied to a silica chip by using a photolithographic masking process. HUBER+SUHNER offers a wide range of PLC splitters for all applications.

CUBO provides a great variety of hi-isolation bandsplitters, based on Thin Film Filters (TFF): Simple Wideband WDMs which create two channels at 1310 & 1550 nm, each with a bandwidth up to 100 nm. Or different CWDM bandsplitters for CWDM upgrades and extensions from e.g. 4 channels to 8 channels. Here, an important characteristic is the number of skipped (not-useable) channels, reaching from 0 to 2 channels.

Our Planar Lightwave Circuit (PLC) Splitters are a complementary splitting option to the fused couplers. When it comes to higher splitting ratios (> 1:4) they offer a lower loss and an overall better performance.

This makes them the ideal choice for FTTx applications with splitting rations of up to 1:64. We offer them as plain devices with or without connectors but as well packaged in accordance with your specific needs in splice trays, cassettes, line cards modules etc.

Switch cubes

We offer a great variety of switches for telecom or sensor applications, ranging from 1x1 to 1x16 ports, applied in variable optical attenuation, protection, bypass switching or sensing applications, supporting multi mode to single mode, latching or non-latching with or without state monitoring.

So, there isn’t much that can’t be switched!
