OLT transceiver boosts FTTH bandwidth utilisation

Keywords:MCR  Mode Coupling Receiver  transceiver 

NeoPhotonics rolls a multi-port Mode Coupling Receiver (MCR) optical line terminal (OLT) transceiver for gigabit passive optical networks (GPON) that is designed to allow fibre-to-the-home (FTTH) operators to optimise bandwidth utilisation 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. 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 fibre outputs where each individual fibre corresponds to the output of a conventional GPON OLT SFP compliant with ITU-T 984 standards.
