Optoplex Optical Interleavers

Asymmetric Optical Interleaver

Asymmetric Optical Interleaver

Conventional Optical Interleaver is Symmetric Optical Interleaver. By "Symmetric" we mean that both "Odd" and "Even" channels have the same passband widths and waveforms. Optoplex offers a new type of Optical Interleaver whose "Odd" and "Even" channels have different passband widths and waveforms. This is FlexSlicer™ Asymmetric Optical Interleaver.
Co-Packaged Interleaver

Co-Packaged Interleaver

Product Description - Co-Packaged Optical Interleaver
Co-packaged interleaver consists of a pair of iterleavers in the same package. There are three input ports and three output ports. The interleaver pair may contain one interleaver (Mux) and one deinterleaver (DeMux), or a pair of (Mux) interleavers, or a pair of (DeMux) interleavers. Customers can specify configurations according to their design and applications.

Standard Optical Interleaver

Standard Optical Interleaver

An innovative technique for expanding the number of channels per fiber involves an optical device, called an optical interleaver. For example, in most DWDM equipment, the standard channel spacing is 100 GHz. But spacing the signal-carrying frequencies every 50 or even 25 GHz can double or even quadruple the number of channels per fibre. This job is accomplished by an optical interleaver. Such a device takes two multiplexed signals with 100-GHz spacing and interleaves them, creating a DWDM signal with channels spaced 50 GHz apart. The process can be repeated, creating even denser composite signals with 25-GHz or 12.5-GHz spacing. The signals at the receiving end are recovered with the same devices used as splitters or optical de interleavers. Thus, devices and/or networks can be upgraded without requiring that all devices be upgraded, or network bandwidth can be increased.
Switchable Optical Interleaver and De-Interleaver

Switchable Optical Interleaver and De-Interleaver

Product Description - Switchable Optical Interleaver
In a switchable interleaver, there are two operation modes:

Mode A: All pass
Mode B: Interleaver
In Mode A, the system operates at any channel spacing, in which all channels pass through the device and output from one of the two output ports as if there is no extra device inserted. When the system is switched to Mode B, the device operates as a normal optical interleaver, such 50-100GHz interleaver. The working principle is schematically shown below.

In Mode B, the device could be a standard symmetric interleaver, or an asymmetric interleaver. Channel spacings are not limitted to 50-100GHz. They can be any frequency pair: between N-GHz and 2N-GHz.
