Oclaro Announces New 400G Products

News

Oclaro has announced a new suite of products that the company says is capable of driving network speeds up to 1Tb and beyond. These components and modules include 400 and 600 Gbps coherent optics, CFP2-digital coherent optical (DCO) modules, and the latest intra-data center modules employing Electro-absorption Modulator Lasers (EMLs) and PAM4 integrated circuits. The company also announced plans to expand its current portfolio of laser die to include its world-class EMLs that it says are in demand for high-speed interconnect applications today.

"Innovation through our core Indium Phosphide technology is key to delivering the higher-speed networks needed to achieve 1Tb and beyond," said Adam Carter, Chief Commercial Officer for Oclaro. "Oclaro is constantly driving new advances that increase density, improve performance and lower power consumption. Our OFC line-up demonstrates our success in all of those critical areas."

Oclaro also demonstrated a number of new products at OFC 2018 in San Diego, California (USA) 13-15 March. Demonstrations included the following:

400 Gbps components: Oclaro showcased its high-bandwidth components operating at 400 Gbps with 16QAM constellation at 64GBaud. This included NLW lasers in conjunction with a single channel, Lithium Niobate Modulator and a 64 GBaud Integrated Coherent Receiver (ICR). The demonstration will show the recovered constellation at the receiver as well as the optical spectrum at the transmitter spectrum validating the operation at 400 Gbps.

1.2Tb in-feed components: This included an Integrated Coherent Transmitter (ICT) operating at 600 Gbps with a 64QAM constellation at 64GBaud.

400 Gbps FR4 module: The company demonstrated a 400 Gbps QSFP56 DD module containing an Oclaro 53GBaud transmitter and reciever optical sub assemblies (TOSA and ROSA) and a gearbox IC to convert between 8x50G PAM4 electrical host signals and 4x100G PAM4 optical line side signals. The demonstration highlighted progress being made towards the realization of 400 Gbps single-mode client side modules for the hyperscale data center.

Live 100 Gbps PAM4 optical transmission: Their demonstration consisted of a 100 Gbps PAM4 optical link using one lane of Oclaro's 4x 53Gbaud transmitter and optical sub-assemblies capable of 400 Gbps optical transmission.
