Finisar Introduces Industry’s First 400G QSFP-DD Active Optical Cable and Transceivers for Switching and Routing Applicatio...
March 13 2018 - 8:00AM
Finisar (NASDAQ:FNSR), the leader in optical communication modules
and VCSEL technology, today introduced several new products to be
demonstrated at OFC, the industry’s largest optical networking and
communication conference and exhibition. The products include 400G
QSFP-DD LR8 and FR8 transceivers, a 400G QSFP-DD active optical
cable, a 100G serial QSFP28 transceiver, and two 50G SFP56
transceivers supporting a variety of next generation of Ethernet
applications. See these products and demonstrations at the San
Diego Convention Center, March 13-15, in Finisar’s booth
#3713.
These new form factors and data rates represent the latest
advances in networking technology, geared toward the next
generation of optics that will operate at 50 and 100 Gb/s per
lane. The 50G and 100G lanes use PAM4 encoding instead of the
traditional non-return-to-zero (NRZ) format, and are crucial to
enable hyperscale data centers, service providers and enterprises
to meet tomorrow’s voracious bandwidth demands.The QSFP-DD (Quad
Small Form Factor Pluggable Interface Double Density) is the latest
module form factor targeting 400G data rates. The design provides
an eight-lane electrical interface, compared to traditional single
or four-lane interfaces, thereby increasing bandwidth, channel
capacity and port density. Defined by the QSFP-DD MSA Group, this
module addresses the need for high-density, high-speed networking
solutions in a backward compatible form factor.
400G QSFP-DD LR8 and FR8 Transceivers Finisar
is unveiling the industry’s first demonstration of a 400G QSFP-DD
LR8 transceiver, whose 10km reach is a critical requirement for
service provider applications. Using 50G PAM4 technology, the
demonstration will show an optical module transmitting data over
10km of duplex single mode fiber (SMF). In addition to the 10km LR8
module being demonstrated, a 2km FR8 variant of this module will
also be available from Finisar, primarily for intra-data center
applications. Both the LR8 and FR8 modules leverage DML
transmitter technology, providing a low power, low risk,
cost-effective solution for 400G.
400G QSFP-DD Active Optical Cable Finisar is
extending its leadership in the market with the addition of the
industry’s first 400G active optical cable (AOC) in the QSFP-DD
form factor. Leveraging VCSEL technology to achieve the lowest
power dissipation and lowest cost structure, this product provides
a desirable alternative to copper cables, which cannot scale to the
required cable lengths at these high data rates. In a joint
collaboration, Finisar is demonstrating the 400G QSFP-DD AOC
running traffic through a Cisco demonstration switch.
“We are pleased to partner with Finisar in this exciting joint
demonstration of Cisco’s 36 Port QSFP-DD Demo Platform and 400G
QSFP-DD optical module at OFC,” said Ray Nering, Product Line
Manager at Cisco. “This demonstration effectively quadruples the
aggregate switch bandwidth while maintaining port density, which is
critical to support the continuing growth in network bandwidth
demand and data center traffic. Cisco expects that QSFP-DD will
become the de facto standard for 400G just as other QSFP form
factors have done so at 40G and 100G.”
100G Serial QSFP28 FR TransceiverFinisar is
introducing a 100G serial FR transceiver in the popular QSFP28 form
factor for inter- data center, transport and router applications
with 2km reaches. While leveraging a standard 4x25G electrical
interface, so that it plugs into standard QSFP28 slots, this module
employs just one serial 100G PAM4 optical channel. Once deployed in
sufficient volume, it is expected to replace existing 100G QSFP28
CWDM4 modules. Finisar also plans to introduce a 500m DR version of
this module. Four of these FR or DR modules will be able to be used
in a fan-out configuration with an IEEE standard 400G DR4 module,
thus providing both 100G point-to-point and 100G-to-400G fan-out
connectivity at 100G per lane. During OFC, the module will be shown
transmitting data over 2km of SMF.
50G SFP56 SR and LR Transceivers Enabling the
next generation of 50G single-lane optical connections, Finisar is
also introducing the industry’s first 50G SFP56 SR and LR
transceivers, using serial PAM4 technology. These modules represent
the next key step in the highly popular SFP+ family of optical
modules that have become ubiquitous in worldwide enterprise, data
center and service provider networks. Primary applications
for these products include server-to-switch and switch-to-switch
50G Ethernet connections, and future 5G wireless applications.
During OFC, Finisar will demonstrate the SFP56 SR module
transmitting over 100 meters of OM4 multi-mode fiber (MMF), and the
SFP56 LR module transmitting over 10km of SMF. Leveraging in-house
vertically integrated optics and IC’s, these modules support
interoperability with previous generations of 25G SFP28 and 10G
SFP+ optical transceivers. Both modules comply with the
corresponding 50GBASE-R specifications as defined in the IEEE
standards and offer 50G PAM4 electrical and optical interfaces.
“Today, we have established a number of industry first optical
modules that will enable Finisar to maintain its leadership
position for the next generation of products,” said Rafik Ward,
Senior Vice President, Global Marketing at Finisar. “Building upon
30 years of success, we are gearing up for a new era of optical
interfaces that will be built on 50G and 100G PAM4 technology. This
will enable us to deliver unprecedented bandwidth to customers in
form factors that are backwards compatible with industry
established footprints.”
