Coherent Announces Industry’s First L-Band 800G ZR/ZR+ Pluggable Transceivers
17 Setembro 2024 - 5:30PM
Coherent Corp. (NYSE: COHR), a leader in high-speed optical
networking technology, today announced the industry’s first L-band
800 Gbps coherent pluggable transceiver in a QSFP-DD form factor.
This innovative product will be showcased at ECOC 2024 in
Frankfurt, Germany, Sept. 23-25, 2024.
Hyperscale data centers and telecom carriers require solutions
to expand fiber capacity at lower costs. By expanding from C-band
to L-band, fiber capacity can double from 32 Tbps to 64 Tbps.
Historically, L-band has been supported with proprietary systems
from network equipment manufacturers. The new standardized 800G
ZR/ZR+ pluggable module from Coherent now allows disaggregation,
supporting an open ecosystem in a smaller and more efficient form
factor.
“Building on the success of the world’s first C-band 140 GBaud
IC-TROSA, Coherent has successfully extended the technology to the
L-band with our new pluggable module,” said Dr. Beck Mason,
Executive Vice President, Telecommunications. “We now feature both
C-band and L-band 800G coherent transceivers with high optical
output power, which delivers best-in-class transmission
performance. We continue to advance the state of the art of optical
transmission in core networks by leveraging the inherent
capabilities of our indium phosphide technology platform to benefit
our end customers.”
“With the ever-growing bandwidth demands of DCI and telecom
networks, L-band transmission has become essential,” said Kyle
Hollasch, Lead Analyst for Transport Hardware at Cignal AI. “L-band
ROADM shipments have nearly doubled over the past 12 months, and
hyperscale DCI requirements are poised to grow the market for
L-band pluggable coherent transceivers even more
rapidly.”
With the availability of L-band 800G ZR/ZR+ transceivers in both
QSFP-DD and OSFP form factors, Coherent enhances the capacity and
performance coverage of IP-over-DWDM (dense wavelength division
multiplexing) applications. These modules enable coherent
interfaces directly on routers and switches, eliminating the need
for additional optical equipment, thus reducing costs by more than
400%.
The 800G ZR/ZR+ transceiver leverages the Coherent L-band 140
Gbaud IC-TROSA-integrated coherent optical subassembly, which
features a high-efficiency, internally designed and manufactured
indium phosphide modulator and receiver combined with an embedded
wavelength-tunable laser. This delivers compelling cost, power,
size, and performance advantages compared with L-band
implementations based on silicon photonics, which need micro-EDFAs,
adding cost and power dissipation and consuming precious real
estate in compact form factors such as QSFP-DD.“Driven by emerging
data-hungry applications, the rapid adoptions of Generative AI
solutions, and ubiquitous video consumption from any place and
device, we marvel at the relentless trajectory of bandwidth
consumption,” said AE Natarajan, Executive Vice President, Chief
Development Officer, Juniper Networks. “Adding L-band 800 ZR/ZR+
pluggable solutions to the toolbox, effectively doubling the
capacity of existing fiber plants, is invaluable and reassuring to
network operators. Fortunately, many operators had the foresight to
deploy L-band-ready line systems, anticipating the future need to
scale network capacity rapidly. By leveraging the QSFP-DD form
factor, Coherent enables vendors like Juniper to deliver highly
flexible and scalable IPoDWDM solutions that facilitate
port-by-port configuration of 800G direct-detect and/or coherent
optics, and now C-band or L-band DWDM optics, mitigating
bottlenecks in a myriad of cloud and telecom use cases.”
Coherent will demonstrate the 800G L-band transceiver module in
a PTX10002-36QDD Juniper router at ECOC 2024, showcasing the
transceiver’s capabilities in an IP-over-DWDM configuration. The
module is designed for various line modulation formats and supports
800 Gbps extended-reach, 600 Gbps, and 400 Gbps long-reach
applications.
Customer sampling will begin in the fourth quarter of 2024.
