Consistent with OIF Implementation Agreement
NeoPhotonics manufactures a portfolio of Biplexer and Triplexer transceivers for FTTH “triple play” (data, voice and video over the same network) applications. These Optical Networking Unit (ONU) transceivers are placed at the customer premise (CPE) and feature duplex operation over a single-fiber, which reduces system cost and simplifies network design and fiber management. ONU transceivers are a key part of our FTTH product portfolio, and NeoPhotonics has shipped more than 5 million ONU transceivers and Optical Sub-Assemblies (OSA) for FTTH applications. NeoPhotonics offers ONU transceivers suitable for both the IEEE 802.3ah GEPON and the ITU/FSAN GPON G.984.5 network standards and for all variations of fiber penetration, whether to the node, curb, business, multi-unit dwelling, or single family home.
In addition to the ONU transceivers, NeoPhotonics manufactures a line of Optical Line Terminal (OLT) transceivers for the central office location of FTTH deployments. OLT transceivers are typically more complex than ONU transceivers, since each OLT transceiver must communicate with up to 64 ONU transceivers.
NeoPhotonics is developing a line of Next Generation PON ONU and OLT transceivers, including 10G/1G and 10G/10G EPON versions compliant with IEEE 802.3av, as well as 10G/2.5G XG-PON1 versions compliant with ITU G.987.
FTTH Outside Plant Splitters and Multi-Channel Filters
A key element for efficient PON systems for FTTH is the passive optical component that combines the signals from multiple subscribers onto one fiber. In current systems this is done by power splitters. Advanced systems are being developed which provide an individual wavelength to each end user, and replace the power splitter with an PIC-based multi-channel athermal filter, known in the industry as an athermal Arrayed Waveguide Grating (AWG).
We manufacture a portfolio of PIC-based 8, 16, 32 and 64 channel power splitters and have introduced PIC-based multi-channel athermal filters designed for out-door installations, which feature industry leading optical performance and are used in a wide range of telecom applications. We also provide PIC-based power splitters which can combine the analog video overlay signal wavelength with the digital signal wavelengths, thus cost-effectively supporting Subscriber Unit Triplexer deployments.
