Mindspeed Intros 10G-EPON Burst-Mode Receivers

Mindspeed Technologies Inc. has launched the world’s first commercially available 10 Gigabit Ethernet Passive Optical Network (10G-EPON) burst-mode receiver chipset. The device features Mindspeed’s 10G burst mode dual-rate transimpedance amplifier (TIA) and burst mode multi-rate limiting amplifier, providing a complete, cost-effective solution for 10G-EPON Optical Line Terminals (OLTs) and is backward-compatible with existing GEPON designs.

The M02138 TIA joins Mindspeed’s broad offering of high-sensitivity TIA solutions that have raised the industry’s performance bar, while reducing the cost of manufacturing PON equipment. The low-power device features dynamic rate selection with fast response times in burst-mode 10Gbps and 1Gbps operation. It also includes burst-mode photocurrent monitoring with a combination of accuracy and output settling time that exceeds OLT requirements. The device is optimized for 10.3Gbps/1.25Gbps performance and can be assembled in a cost-effective standard 5-pin or 6-pin receiver or bi-directional optical subassembly (ROSA/BOSA).

The TIA’s companion, the M02142, is a high-performance, feature-rich 11.3Gbps limiting amplifier that includes integrated fast loss of signal (LOS) detection and is well suited for 10G-EPON burst-mode applications. The compact, low-power device provides input sensitivity of 3mV peak-to-peak (mVpp) at full data rate and, with its wide input dynamic range, can also accept up to 1.6V peak-to-peak (Vpp) differential input voltage. Fast output settling time and dynamic rate selection are supported for 10G-EPON OLT applications.

Mindspeed is collaborating with Cyoptics to create a receiver module for customers using its burst-mode TIA. Cyoptics’ ROSA combines Mindspeed’s M02138 with Cyoptics’ avalanche photodiode (APD).
