New optical line terminal transceiver lowers first installed cost for FTTH networksNeoPhotonics Corporation has announced a multiport Mode Coupling Receiver (MCR) optical line terminal (OLT) transceiver for gigabit passive optical networks (GPON) in an SFP form factor for use in fiber-to-the-home (FTTH) networks. The 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).
FTTH has become a leading wire-line broadband access technology of the 21st century and PON represents a critical network architecture. 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.
The first version is a 4-port MCR GPON Class B+ OLT in a pluggable SFP form factor, which is designed to increase the split ratio in a standard PON from 1:32 to 1:128 while maintaining the original link budget and reach. This module features a connector with 4 fiber outputs where each individual fiber corresponds to the output of a conventional GPON OLT SFP compliant with ITU-T 984 standards.
NeoPhotonics is showcasing the new MCR GPON OLT alongside its existing product portfolio, including Integrated Coherent Receivers and Narrow Linewidth Tunable Lasers for 100G coherent communications and 100G 10x10 CFP Transponders for client side transmission, at the ECOC Exhibition in Amsterdam (September 17-19, 2012, RAI Exhibition Center, booth 658).
