Multicast Switch
Multicast Switch

Multicast Switches are wavelength insensitive (and thus transmission speed independent) optical switches which can connect any number of optical inputs and outputs in a fully non-blocking non-restrictive way. This functionality is built using a large array of optical power splitters interconnected to a large array of optical switches. N 1xM splitters connected to M 1xN switches form an NxM multicast switch. A typical MCS configuration is 8×16, however both smaller and larger port-count product versions are also available.

Mux/Dmux (MDM) Module, Rack Mounted

NeoPhotonics Athermal Arrayed Waveguide Gratings (Athermal AWGs) are available in rack mountable shelves with bulkhead connectors. Different AAWG and MUX/DMUX combination and other components can be intergrated in the same shelf based on customer requirement. NeoPhotonics offers full ODM capability with a complete line of Athermal AWGs with channel spacings of 50 GHz, 75 GHz, 100 GHz, and 150 GHz, covering the C and L Bands, for shelf integration.

Inline Digital Power Monitor
Inline Digital Power Monitor

NeoPhotonics Power Monitor is a low-cost and compact device featuring a digital readout of the instantaneous power of the transmitted signal. Fiber continuity is maintained, allowing high directivity, low loss, and low PDL. The intuitive user interface and long battery life are also ideal for testing and monitoring optical power of FTTX, Data Center, Metro and Long Haul optical networks.

The fingertip controls allow the quick selection of the appropriate wavelength(s) (up to three), sampling rate and relative or absolute power reading. A USB interface is also available for device power, remote control, and monitoring. User interface solution and API are available upon request.

DWDM Variable Optical Attenuator Mux Dmux

NeoPhotonics VOA Multiplexer, or VMUX, combines up to 48 individually-controllable VOAs with a 48 Channel AWG in a single compact module. The VMUX is ideal for power leveling, prior to amplification in DWDM systems and can be used in Optical Add Drop Multiplexer configurations. Integrated products, such as VOA Multiplexers, which combine multiple different functions onto a single PLC chip provide a compact cost-effective solution for optical network needs.

DWDM Mux/Dmux Arrayed Waveguide Grating AWG Athermal
DWDM Mux/Dmux Arrayed Waveguide Grating AWG Athermal

NeoPhotonics Athermal Arrayed Waveguide Grating (Athermal AWG) requires no electrical power for stabilization and can be used as direct replacements for Thin Film Filters for cases where no power is available at the shelf. They can be used for indoor CO and also be used outdoors over -40ºC to +85ºC in Access applications, extending the cost performance benefits of AWGs. NeoPhotonics Athermal AWG is an integrated PLC component that multiplexes or demultiplexes 8 to 96 channels onto a single fiber, and follows the mechanical requirements of the Multi Source Agreement for Athermally-Stabilized AWG Modules. NeoPhotonics offers a full line of MSA AWGs with channel spacings of 50 GHz, 75 GHz, 100 GHz, and 150 GHz, covering the C and L Bands. NeoPhotonics Athermal AWGs can be designed for different Telecom, DCI, or Access applications, and optimized for direction detection or different coherent detection schemes [for single wavelength, supporting 800GBits/s up to 1.6T].

Inline Optical Power Monitor

NeoPhotonics Inline Optical Tap Detectors (also known as EigenLight Inline Optical Tap Detectors) are used for the measurement of optical fiber power while preserving the continuity of the transmitted signal inside the core of the fiber. Unlike conventional tap detectors, the NeoPhotonics inline tap detector does not use any lens or partial reflector and only a small fraction of the light is removed from the core. Insertion loss can be as low as 0.05dB, including an extremely low polarization-dependent loss, which makes the device ideal for highly-sensitive applications.

Inline tap detectors are used in 100/400G Long Haul, Metro, FTTX, and Data Center Optical Networks, as well as optical networking subsystems (ROADMs, EDFAs, WSS, etc.) where low insertion loss and low PDL optical components are required.

Variable Optical Attenuator
Variable Optical Attenuator

NeoPhotonics MEMS VOA is an ultra-compact variable optical attenuator that easily drops into any optical network application. Both bright and dark configurations are available, with very low insertion loss and polarization-dependent loss, high dynamic range and high off-state extinction. The hermetically-sealed MEMS chip is insensitive to shock and vibration and is ESD safe up to 500V.

NeoPhotonics MEMS VOA is ideal for receiver protection or transponder power control, and it is also widely used in EDFAs of for equalization in multi-channel systems.
