10-Gbps electroabsorptive modulated laser bidirectional optical subassembly using novel two-window flat package for passive optical network

Abstract

Abstract.A novel 10-Gbps bidirectional optical subassembly (BOSA) comprised of a 1577 nm electroabsorptive modulated laser (EML) transmitter optical subassembly (TOSA) and 1270 nm avalanche photodiode (APD) receiver optical subassembly (ROSA) was developed. Here, a 10-Gbps microdevice compatible two-window flat package was proposed to simplify the EML BOSA structure, considering both the mechanical reliability and cooling performance. As a result, an optical output power of 8 dBm was obtained due to a high optical coupling efficiency of 60%, an extinction ratio of 7 dB, and a dispersion penalty at 20 km transmission of less than 1.5 dB for the EML TOSA. The APD ROSA sensitivity was -21.5 dBm at a bit error rate (BER) of 10 − 12 and -27 dBm at a BER of 10 − 3 without forward error correction. In addition, the sensitivity penalty of the APD ROSA due to signal crosstalk was less than 1.2 dB. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).

Physical Media Dependent Prototype for 10-Gigabit-Capable PON OLT

“…Figure 6 shows a BOSA module composed of a 10-Gbit/s EML Tx and 2.5-Gbit/s BM-Rx to satisfy the XG-PON1 OLT requirements. Using a uniquely designed bidirectional mini-flat package [13], compatible with a standard 10-Gbit/s miniature device (XMD) MSA, the EML Tx and BM-Rx are fully integrated in a miniature component for bidirectional transmission through a single core of SMF.
