Mindspeed Technologies, Inc. has introduced the M02150 burst-mode driver chipset family for next-generation GPON (XG-PON1) networks. The chipset features a programmable 3.1-Gbps dual-closed-loop burst mode laser driver integrated with an 11.3-Gbps limiting amplifier. The chipset features power-saving sleep and current reduction modes in a 4x4-mm package, the company says.

The new M02150 device can be used with companion Mindspeed chips on the optical line termination (OLT) side of the access network to create end-to-end uplink and downlink services, either in traditional optical modules or interfaced to bidirectional optical subassemblies (BOSAs) that can be mounted directly onto the XG-PON1 optical networking unit (ONU) or OLT board.

“Our M02150 chipset family offers low-power consumption, performance monitoring, and dual-closed-loop laser driver operation in a small, low-cost package,” said Hasnain Bajwa, senior vice president and general manager, high performance analog (HPA) at Mindspeed.

Mindspeed has worked with optical component vendor CyOptics, Inc. to create a complete BOSA-on-board reference design that integrates CyOptics’ XG-PON1 ONU BOSA with the M02150/51 XG-PON1 driver chipset.

Mindspeed also has introduced a second, related chipset, the M02151 driver, that has integrated, electrically erasable programmable read-only memory (EEPROM), used to store calibration and performance settings and can support more than one million write cycles. This feature reduces overall system cost and optimizes the driver for BOSA-on-board designs by supporting multiple re-calibrations, and enables it to operate with or without out external control. CyOptics also offers a XG-PON1 OLT BOSA that interfaces with these devices in an OLT module.

The M02150 burst-mode driver family and M02035 and M02172 OLT chipset are available now. They can be used in both 10G-GPON - XGPON1/ITU G.987.2 and 10G-Ethernet passive optical network (EPON)-10G/1GBase-PRX applications.
