Coherent optics players target the network edge for growth

The market for optical links for reaches between 10km and 120km is emerging as a fierce battleground between proponents of coherent and direct-detection technologies. 

Interest in higher data rates such as 400 gigabits is pushing coherent-based optical transmission from its traditional long-distance berth to shorter-reach applications. “That tends to be where the growth for coherent has come from as it has migrated from long-haul to metro,” says Tom Williams, senior director of marketing at Acacia Communications, a coherent technology supplier.

Williams points to the Optical Internetworking Forum’s (OIF) ongoing work to develop a 400-gigabit link for data centre interconnect. Dubbed 400ZR, the project is specifying an interoperable coherent interface that will support dense wavelength-division multiplexing (DWDM) links for distances of at least 80km.

Acacia looks to co-package its coherent PIC and DSP-ASIC

  • Acacia Communications is working to co-package its coherent DSP and its silicon photonics transceiver chip. 
  • The company is also developing a digital coherent optics module that will support 400 gigabit. 

Acacia Communications is working to co-package its coherent DSP and its silicon photonics transceiver chip. The line-side optical transceiver company is working on a digital coherent optics module that will support 400 gigabits.

Acacia announced last November that it was sampling the industry’s first CFP2 Digital Coherent Optics (CFP2-DCO) that supports 100- and 200-gigabit line rates. The CFP2-DCO integrates the DSP and its silicon photonics chip within a CFP2 module, which is half the size of a CFP module, with each chip packaged separately.

Enabling coherent optics down to 2km short-reach links

Silicon photonics luminaries series

Interview 5: Chris Doerr

Chris Doerr admits he was a relative latecomer to silicon photonics. But after making his first silicon photonics chip, he was hooked. Nearly a decade later and Doerr is associate vice president of integrated photonics at Acacia Communications. The company uses silicon photonics for its long-distance optical coherent transceivers.

Acacia Communications made headlines in May after completing an initial public offering (IPO), raising approximately $105 million for the company. Technology company IPOs have become a rarity and are not always successful. On its first day of trading, Acacia’s shares opened at $29 per share and closed just under $31.

Acacia unveils 400 Gigabit coherent transceiver

  • The AC-400 5x7 inch MSA transceiver is a dual-carrier design
  • Modulation formats supported include PM-QPSK, PM-8-QAM and PM-16-QAM
  • Acacia’s DSP-ASIC is a 1.3 billion transistor dual-core chip 

Acacia Communications has unveiled the industry's first flexible rate transceiver in a 5x7-inch MSA form factor that is capable of up to 400 Gigabit transmission rates. The company made the announcement at the OFC show held in Los Angeles. 

Dubbed the AC-400, the transceiver supports 200, 300 and 400 Gigabit rates and includes two silicon photonics chips, each implementing single-carrier optical transmission, and a coherent DSP-ASIC. Acacia designs its own silicon photonics and DSP-ASIC ICs.
