Coherent’s 400G ZR+ QSFP-DD-DCO transceiver wins ECOC Industry Award for Optical Integration
Coherent Corp of Saxonburg, PA, USA, which provides photonics technology for communications and aerospace & defense applications, says that its 400G ZR+ QSFP-DD-DCO optical transceiver has won the Industry Award for Optical Integration at the European Conference on Optical Communication (ECOC 2022) in Basel, Switzerland (19–21 September).
The 400G ZR+ transceiver’s high transmit output power of 0dBm enables true IP-over-DWDM deployments in metro and regional optical transport networks, eliminating an entire layer of optical equipment and thereby significantly reducing both capital and operational expenditures for network operators.
“This award for optical integration speaks to our ability to transform line cards into industry-standard pluggable modules,” says chief marketing officer Dr Sanjai Parthasarathi. “The availability of 400G with such high output power in a QSFP-DD form factor is a game-changer due to its compatibility with router interfaces. Now, service providers can connect routers directly to access, metro and regional optical transport networks without client interfaces. This IP-over-DWDM network architecture achieves huge savings in upfront costs and ongoing expenses.”
The 400G ZR+ QSFP-DD-DCO transceiver is based on proprietary indium phosphide (InP) technology, which is an intrinsic enabler of the transceiver’s 0dBm output power. Furthermore, InP components consume a low enough amount of power to be suitable for the small QSFP-DD form factor.
In March, Windstream Wholesale announced that it had completed field trials (over a 1000km link between Phoenix and Los Angeles) using the 400G ZR+ QSFP-DD-DCO transceiver from Coherent. Windstream also demonstrated transmission over up to 24 cascaded reconfigurable optical add/drop multiplexers (ROADMs) in a lab environment.
Coherent showcased the 400G ZR+ QSFP-DD-DCO transceiver in a live demonstration at ECOC. Also, at ECOC’s Market Focus, director of product management Dr Gert Sarlet presented the talk ‘Coherent Optics in Client Pluggable Form Factor Enables IP-over-DWDM in Disaggregated Transport Networks’.
