CST Global’s reports eye-diagram performance of XG-PON 1270nm 2.5G lasers up to 85°C
III-V optoelectronic foundry Compound Semiconductor Technologies Global Ltd (CST Global) of Glasgow, Scotland, UK (a subsidiary of Sweden’s Sivers IMA Holdings AB) says that samples of its 1270nm 2.5Gb/s lasers have shown outstanding eye-diagram performance, with eye mask margins of 34% and extinction ratios up to 9.3dB.
Significantly, the lasers performed over and above the requirements of the ITU-G.987 specification for XG-PON (10 Gigabit-capable passive optical networks) at temperatures up to 85°C and have exceeded 2000 hours in accelerated life testing. Designed for the global fiber-to-the-home (FTTH) market - which is rising at a compound annual growth rate (CAGR) exceeding 7%, from $7.3bn in 2019 - the lasers are available in TO-can and die-on-tape formats.
“Our next-generation XG-PON 1270nm 2.5G lasers address the worldwide FTTH market,” says Euan Livingston, VP sales & marketing at CST Global, who is attending the China International Optoelectronic Exposition (CIOE 2019) in Shenzhen, China (4-7 September). “We are seeing increased demand in this market, especially in China, where the strong preference for UK-sourced materials gives us a unique position as a supplier,” he reckons. “The TO-can and die-on-tape formats provide our customers with flexibility in both their design cycle testing and in meeting production demands in 2019 and beyond.”
