Ridgefield Park, New Jersey, September 19, 2019 — OE Solutions announces the 50G bidirectional
QSFP28 ER ST optical transceiver. The optical transceiver, which operates in the O-band with a
standard-temperature (ST) rating in a QSFP28 form factor, offers a transmission distance of 40km.
The 50G BIDI ER ST transceiver, which is aimed especially at wireless mid-haul applications, joins OE
Solutions’ extensive portfolio of 10G, 25G and now 50G optical transceivers for wireless access
networks, including front-, mid- and backhaul.
The ambitious goals of the wide range of performance metrics in the 3GPP release-16 standard,
which is expected to be ratified in 2020, impact the optical access network supporting 5G wireless
services dramatically. Much higher capacities need to be delivered to a much larger number of
antennas. In addition, compute and storage resources will be required closer to the antennas than was
the case for LTE and previous-generation wireless services. As the network architectures evolve to
support these changes, new optical transceiver requirements have emerged.
The 50G PAM4 BIDI ER optical transceiver leverages PAM4 encoding to enable 50G duplex
connectivity over a single fiber. When considered in conjunction with OE Solutions’ 10G and 25G NRZ
BIDI transceivers, service providers can size a single-fiber connection cost-efficiently to match the
bandwidth demand. The 50G PAM4 transceiver employs dual-25G electrical interfaces of a QSFP28
standards-compliant module design. As such, the module offers a simple way to double the bandwidth
over a single-fiber link without having to install filters for wavelength multiplexing.
“We are very excited to launch our first 50G transceiver product for wireless access network
applications”, said Per Hansen, VP of Marketing and Sales at OE Solutions, and continued “We have
a long history of working closely with the leading equipment manufacturers and service providers to
deploy new generations of wireless infrastructure. As 5G increases the bandwidth requirements for the
optical part of the access network and new network architectures are being deployed, the industry
demands new optical transceivers solutions such as this 50G device, which leverages PAM4
modulation to provide the needed bandwidth, reach and cost-efficiency.”
