CORRECTING and REPLACING Source Photonics to Demonstrate Fully Integrated 400GBASE-FR8 OSFP Module based on 25Gbaud PAM4 Technology at OFC 2017 in Los Angeles, CA

WEST HILLS, Calif.–(BUSINESS WIRE)–#100G–A multimedia asset accompanying this release has been removed.

The release reads:


Source Photonics, a leading provider of optical transceivers for data
center and broadband access connectivity, is proud to announce the first
demonstration of a fully integrated 400GBASE-FR8 OSFP module. This
represents the first duplex single mode fiber module in the industry
with a form factor capable of supporting a 12.8Tb/s 1RU switch.

The company’s 400G OSFP module represents a 4x improvement in faceplate
density over current 3.2Tb/s switches supported by 100G QSFP28 LR4,
CWDM4, and PSM4 modules. The module integrates 8 transmit and receive
channels each operating at 50Gbps using 25Gbaud PAM4 modulation on both
the electrical interface and the optical interface. The company will be
showcasing the demonstration at the Optical Fiber Communication (OFC)
trade show this week in Los Angeles, CA.

This initial demonstration will consist of an OSFP chassis with
integrated 8-wavelength TOSA and ROSA components, operating in
electrical loop back through the OSFP connector with a display of the
eight transmit wavelengths on an optical spectrum analyzer. The initial
prototype is possible through the development of a compact TOSA housing
all eight EML lasers and wavelength multiplexing optics, as well as
development of a compact ROSA package housing eight PD chips, TIAs, and
wavelength de-multiplexing optics.

“We have been able to extend our industry leading small form factor
wavelength integration platform of the highly successful QSFP28 from
four-wavelengths to eight-wavelength for these new 400G optics,” says
Patrick Cui, Lead Designer at Source Photonics. “Coupled with rapidly
maturing 25Gbaud PAM4 electronics, Source Photonics is well positioned
to lead the industry in small form factor 400Gbps optical deployments.”

“We aim to develop solutions that help operators deploy revolutionary
new services and dramatically reduce total cost of ownership.
Quadrupling switching bandwidth per 1RU promises considerable Opex and
Capex savings for operators as they are asked to support rapidly growing
customer demand for applications such as analytics, machine learning,
and content delivery,” says Ed Ulrichs, PLM of high speed products at
Source Photonics. “Our dual fiber, high density solution can provide
game changing alternatives for early adopters of 400G solutions for
higher tier switch to core connectivity.”

Paired with a single channel 100G demonstration, Source Photonics is
leading the development of technology and products to facilitate the
industry’s migration from traditional NRZ solutions to PAM4 based small
form factor, high density 400Gbps solutions.

Source Photonics will be exhibiting the 400G OSFP-FR8 at their booth
#3011 at OFC 2017 to be held at the Los Angeles Convention Center from
March 21-23, 2017. For further information or to schedule an
