FTTH Transceivers


NeoPhotonics Corporation, a designer and manufacturer of photonic integrated circuit, or PIC, based modules and subsystems for bandwidth-intensive, high speed communications networks, today announced a multiport Mode Coupling Receiver (MCR) optical line terminal (OLT) transceiver for gigabit passive optical networks (GPON) in an SFP form factor and for use in fiber-to-the-home (FTTH) networks.

This new Mode Coupling Receiver GPON OLT transceiver (MCR GPON OLT) is designed to allow FTTH operators to optimize bandwidth utilization in their passive optical networks (PON).  The MCR OLT represents the latest addition to the NeoPhotonics transceiver portfolio, which includes a broad range of high-capacity 10G PON, SFP+, XFP and CFP modules.

One common approach to reduce the cost of installation is to keep split ratios high during the initial deployment phase when subscriber take rates can begin low. The MCR GPON OLT is designed to increase split ratios without degrading system performance due to additional link loss.  NeoPhotonics used its platform PIC technology to develop the MCR in an economical SFP form factor, which is compatible with the installed base of GPON OLT line cards, thus offering network operators a new powerful tool to leverage their installed base and reduce their installed first cost.
