Lightwaves 2020 High Band Isolation WDM 1310/1550

High Band Isolation WDM 1310/1550

Lightwaves2020's thin film filter (TFF) based Ultra-Wide, Ultra High Isolation band WDM provides greatly improved isolation (>45 dB) and greater operational bandwidth (1310/1550) than typical WDM couplers while providing optimal performance.

The TFF based WDM has the same 5.5 x 40 mm cylindrical package as conventional 3-port devices, saving on board space. With the addition of a band splitter, an upgrade option is provided for legacy 1310/1550 nm systems in access, CATV and other networks that enables them to expand their capacity through CWDM technology.

Lightwaves 2020 Compact 4-channel CWDM Multiplexer/Demultiplexer (MCWDM) Module

Compact 4-channel CWDM Multiplexer/Demultiplexer (MCWDM) Module

Lightwaves2020 4-channel CWDM mux/demux product is only 50x31x8.8mm in dimension! Utilizing Ligthwaves2020's proprietary free space TFF technology, the product guarantees pass bandwidth of 7.5nm over -20 ~ 70C. The total insertion loss for all 4 CWDM channels is only ~ 0.8dB, giving much more flexibility on loss budget to the system designer. The product has wide applications in metro core and access networks, enterprise, CATV, 3G wireless telephony, PON and FTTx networks. The wide operating temperature range is particularly suitable for outdoor applications.

Manufactured using low thermal drift filters and proprietary packaging technologies, the 4-channel CWDM is designed to separate (demultiplex) or combine (multiplex) four coarse WDM channels. The demultiplexer (demux) modules are installed before the receivers in optical networks and the multiplexer (mux) modules are installed after the transmitters. The modules differ in that the demux modules require additional channel isolation in order to obtain clear signals. Module configuration can be custom-designed to meet specific system requirements.

Lightwaves 2020 Compact 8-Channel CWDM Demultiplexer/Multiplexer Module (MCWDM)

Compact 8-Channel CWDM Demultiplexer/Multiplexer Module (MCWDM)

Lightwaves2020 8-channel CWDM demux/mux product is only 50x31x8.8mm in dimension! Utilizing Ligthwaves2020's proprietary free space TFF technology, the product guarantees pass bandwidth of 7.5nm over -20 ~ 70C. The total insertion loss for all 8 CWDM channels is only ~ 1.2dB, giving much more flexibility on loss budget to the system designer. The product has wide applications in metro core and access networks, enterprise, CATV, 3G wireless telephony, PON and FTTx networks. The wide operating temperature range is particularly suitable for outdoor applications

Manufactured using low thermal drift filters and proprietary packaging technologies, the 8-channel CWDM is designed to separate (demultiplex) or combine (multiplex) eight coarse WDM channels. The demultiplexer (demux) modules are installed before the receivers in optical networks and the multiplexer (mux) modules are installed after the transmitters. The modules differ in that the demux modules require additional channel isolation in order to obtain clear signals. Module configuration can be custom-designed to meet specific system requirements.
