聯(lián)系我時，請告知來自 智慧城市網(wǎng)該Interleaver 采取的是一種交叉濾波方案。按照奇偶分配的原則，把DWDM信號分解為兩組信號流。分解后的每組信號頻道間隔比原來增大了一倍，從而降低了后面密集波分復(fù)用器的難度。支持200GHz到100GHz間隔、100GHz到50GHz間隔、50GHz到25GHz間隔以及定制等一系列interleaver器件，包括對稱型、非對稱型、可開關(guān)型等。
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 fiber. 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.
Optoplex's Optical Interleaver products are based on patented Step-Phase Interferometer design. Used as a Demux (or Mux) device, an optical interleaver separates (or combines) the odd and even channel signals (see the schematic diagram below). Each optical interleaver device is optimized to cover either C- or L-bａnd wavelengths, with the option of covering C+L band. The current standard optical interleaver product family supports 100-200, 50-100, 25-50, and 12.5-25 GHz channel spacing, covering up to 90, 180, 360, and 720 channels, respectively, as well as other custom spacings in that range, such as 33.33-66.66 GHz. Dual-stage optical interleavers are also available. For asymmetric optical interleaver, please visit the other web page.
Optoplex's Optical Interleavers have wide and flat passband, low (ａnd customizable) dispersion, low and uniform insertion loss, low PDL, high channel isolation and very low thermal drift.
