Global compact modular revenue grew 24 percent in the third quarter of 2020 (3Q20) over the prior year, versus just 7 percent growth for the total optical market, according to the latest Transport Applications Report from market research firm Cignal AI. Cignal AI defines “compact modular” as small form factor optical hardware that is designed for use in open and disaggregated networks.

“Compact modular is gaining popularity with a wider set of network applications and operators due to the continued adoption of disaggregation outside cloud and colocation,” said Scott Wilkinson, lead analyst at Cignal AI. “The market saw extraordinary growth in Asia Pacific over the last two quarters, with sales in the region now approaching those of EMEA.”




Meanwhile, the 400ZR market is getting underway, with several hundred modules shipped for testing and evaluation in 3Q20. “The demand pipeline for 400ZR remains strong and operators are pleased with the prototypes under evaluation,” said Andrew Schmitt, directing analyst at Cignal AI. “Acacia had a huge quarter thanks to a large buildout at Amazon AWS.”

More Key Findings from the 3Q20 Applications Report

  • Although Ciena reported a flat quarter overall for optical sales, its compact modular sales were up 18 percent year over year, and the company maintained its market leadership by a wide margin
  • Compact modular sales in APAC grew by more than 75 percent in the quarter; Huawei (mostly in China), Fujitsu (in Japan) and Nokia all more than doubled their sales in the region
  • Year-over-year sales of packet-OTN equipment grew only in APAC this quarter, and sales in North America declined by more than 25 percent
  • Overall compact modular sales growth is forecast to decelerate to low single digits in 4Q20 as capex budgets evaporate, especially in North America
  • Pluggable coherent optics are projected to account for 40 percent of the high-performance optical market by 2024
  • Shipments of fixed 400 Gbps+ coherent ports jumped 65 percent sequentially, to over 35,000 ports in the quarter

Based on their different requirements, OIF developed specs and tweaked the channel requirements so the IA would benefit both data center and network operators. While developing the IA, OIF collaborated closely with other standards bodies.

The 400ZR IA addresses two applications:

  • Amplified, point-to-point DWDM links with reaches of 120 km or less
  • Unamplified, single wavelength links with a loss budget of 11dB
The IA aims to enable interoperable, cost-effective, 400Gbps implementations based on single-carrier coherent DP-16QAM modulation, low-power DSPs supporting absolute (Non-Differential) phase encoding/decoding, and a Concatenated FEC (C-FEC) with a post-FEC error floor <1 .0e-15.="" 400gbase-r="" 400zr="" a="" as="" operates="" p="" phy.="">

No restriction on the physical form factor is implied by the IA (QSFP-DD, OSFP, COBO, CFP2, CFP8), but the specifications target a pluggable DCO architecture with port densities equivalent to grey client optics.

NeoPhotonics samples 400ZR OSFP coherent transceiver

NeoPhotonics began sampling its new 400ZR ClearLight OSFP transceiver to a leading cloud -related customer.

The new transceiver utilizes NeoPhotonics Silicon Photonics Coherent Optical Subassembly (COSA) and low power consumption, ultra-narrow linewidth Nano-ITLA tunable laser, combined with the latest generation of 7 nm DSP, to provide full 400ZR transmission in a standard data center OSFP form factor.

NeoPhotonics said its new 400ZR ClearLight OSFP transceiver can be plugged directly into switches and router, simplifying data center interconnect (DCI) networks by eliminating a layer of network equipment and a set of short reach client-side transceivers. The new OSFP module is capable of tuning to 75 GHz or 100GHz spaced wavelength channels, as specified in the OIF agreement, and operates in 400ZR mode for Cloud DCI applications.  For longer metro reaches, the module  is designed to support 400ZR+ modes.

This ClearLight OSFP module can also be optionally provisioned to tune over the entire “Super C-Band”, or up to 6.4 Terahertz, increasing the capacity of an optical fiber by up to 50% over standard implementations.  NeoPhotonics provides arrayed waveguide gratings for multiplexing and de-multiplexing with 75GHz and 100GHz wavelength channel spacings, supporting 85 and 64 channels respectively, with filter responses optimized for high baud rate coherent signals.


Inphi samples first 400ZR QSFP-DD transceiver

Inphi has begun sampling its COLORZ II 400ZR QSFP-DD pluggable coherent transceiver for cloud data center interconnects (DCIs) to major cloud operators and OEMs.

Inphi cites several industry firsts for its COLORZ II 400ZR QSFP-DD:

  • 400G single-chip, coherent Silicon Photonics Integrated Circuit (PIC) that includes all transmit and receive functions 
  • Innovative, low cost, passive alignment of fiber to the PIC that eliminates the complicated active alignment, using traditional optics
  • Low power, high performance, 7nm CMOS-based coherent DSP enabling 400ZR as well as extended reach 100/200/300/400G ZR+ modes
  • Integrated industry standard firmware management interface that enables full performance monitoring previously only available in DCI or transport systems directly from the optical module

 The 400ZR standard promises to lower the cost and power consumption of metro data center interconnect (DCI) by enabling switch and router companies to offer the same density for both coherent DWDM and client optics in the same chassis. This eliminates a layer of network connectivity that was previously required and supports high capacity DWDM connectivity directly from data center switches.

Inphi said its COLORZ II represents a massive increase in switch rack capacity, while reducing the power consumption by as much as 80%. COLORZ II delivers up to 14.4T of capacity per rack unit (RU), compared to 2.4T or 3.6T per RU on competing solutions, representing a 4-6 x increase in throughput per chassis.
