Source Photonics to Demonstrate a 2x50G-PAM4 QSFP28 100G Module at OFC 2016, the Latest Addition to Their Leading Portfolio of Small Form Factor 100G Optical Transceivers


WEST HILLS, Calif., March 21, 2016 (BUSINESS WIRE)–Source Photonics will demonstrate a 2x50G-PAM4 QSFP28 100G module at OFC 2016 on March 22-24, adding to its leading portfolio of small form factor 100G products. The PAM4 demonstration comes on the heels of Source Photonics’ industry leading release of the 100G QSFP28 LR4 platform of products. Source Photonics announced first in industry sampling of the LR4 and LR4 Lite in March 2014 and mass production in March 2015. In January 2016, Source Photonics announced the shipment of its 10,000th QSFP28 module to customers.

For 100G and higher products, Source Photonics has developed a common platform using EMLs for both 2km and 10km CWDM4, LR4 Lite, and LR4 products operating with typical power consumption of less than 3.5W. The unique design reduces component count and complexity versus DML solutions and enables Source Photonics to leverage the same design blocks and manufacturing footprint to support all three products and future products like 50G-PAM4 and 100G-PAM4.

Source Photonics now takes the next step in 100G leadership by reducing the complexity and component count of 100G transceivers by a factor of two using 50G-PAM4 modulation. The 2x50G-PAM4 QSFP28 will operate at a worst case power consumption of 3.5W at 70C case temperature and support KR4 FEC in the host IC. The company is also in development to support a KP4 FEC implementation similar to the FR8 requirements for 8-channel 400G standards.

Source Photonics, which has now released 100G QSFP28 LR4, QSFP28 LR4 Lite, CFP4 LR4 and CFP4 OTU4 to mass production, and will be in production on the QSFP28 CWDM4 exiting Q2 2016, continues to grow its portfolio of 100G+ product offerings.

“Cloud scale and Web 2.0 datacenters are demanding increased volume and lower cost 100G small form factor products and reducing component count is a critical long term solution,” says Sheng Zhang, Chief Scientist at Source Photonics. “We are demonstrating a major step towards the productization of PAM4 technology that will be instrumental in the cost reduction of 100G QSFP28 products and the release of initial 400G products.”

Source Photonics will be demonstrating its 2x50G-PAM4 QSFP28 at OFC in Anaheim Convention Center on March 22-24, 2016. Please visit us at booth number 2709. For more information, you may also visit our website at
