OIF Approves IC-TROSA Implementation Agreement, Specifications Speed Delivery of a Higher Level of Integration for Transmit and Receive Optical Components

IC-TROSA IA enables miniaturization of optical transceiver modules and lowers the component cost for 400ZR, metro, data center interconnect (DCI) applications

Fremont, Calif.—September 23, 2019OIF, where the optical networking industry’s interoperability work gets done, continues its efforts to reduce cost and speed market adoption of next-generation solutions through the approval of the Integrated Coherent Transmitter-Receiver Optical Subassembly (IC-TROSA) Implementation Agreement (IA). IC-TROSA integration will be demonstrated during this week’s OIF Physical and Link Layer (PLL) Interoperability Demo at ECOC 2019 in Dublin, Ireland (OIF booth 441).

“The IC-TROSA project took an aggressive approach to coherent optical component integration and has delivered two new package designs incorporating TX and RX integration, common digital controls and performance monitoring all in a small form factor package,” explained Scott Grindstaff, Director R&D, ADVA, and IC-TROSA IA Technical Editor. “Additionally, package specific features such as fiber-free interface and solder reflow compatibility have been incorporated.”

The optical sub-assembly supports high-bandwidth and high-order dual-polarization quadrature amplitude modulation (QAM) operations and is suited for data center interconnect, metro and long-haul applications. As module sizes decrease, coherent optics components need similar size reductions to enable next generation multi-terabit switches, line cards and transport platforms.

“The IC-TROSA IA is a solution for density requirements for line cards, front-pluggable and future on-board coherent 400G+ optical modules,” said Karl Gass, OIF PLL Working Group, Optical Vice Chair. “It aims to standardize a photonic package for coherent applications that is easy to use while leaving the internal implementation to the vendor.”

The IC-TROSA Type-1 is optimized for silicon photonics technology and uses a surface-mount package with Ball Grid Array (BGA) electrical interface. Important advantages include an increased electrical bandwidth and solder reflow capability. The IC-TROSA Type-2 is optimized for Indium Phosphide technology and uses a gold-box package with flex-cable electrical interface. Important advantages include an integrated tunable laser and a duplex LC optical connector.

The IC-TROSA’s low power dissipation and miniature footprint enables small form factor digital coherent optics (DCO) transceivers in a QSFP-DD or OSFP form factor, as well as very high-density coherent line card or daughtercard designs. Devices can support multiple modulation formats, including QPSK, 8QAM, and 16QAM, at symbol rates up to 64Gbaud, enabling data transmission up to 600 Gb/s.

FierceTelecom – What is 400ZR?

Aimed predominantly at short-reach, single-span fiber optic links for Data Center Interconnect (DCI), 400ZR is an interoperable networking Implementation Agreement (IA) in progress by the OIF. It defines a footprint-optimized solution for transporting 400Gb Ethernet over DCI links targeting a minimum of 80 km. Enabled by advanced coherent optical technology design targeting small, pluggable form factor modules such as QSFP-DD and OSFP, 400ZR proposes a technology-driven solution for high capacity data transport, matched to 400GE switch port market introduction.

OIF Delivers on Enabling Next Generation Network Flexibility through Three New Interoperability Agreements

OIF efforts provide the growing networking industry with advanced network connectivity, provisioning and flexibility combined with improved data rates

Fremont, Calif.—October 23, 2018 – Continuing its efforts to drive network connectivity and flexibility worldwide, OIF announced three Interoperability Agreements (IAs) aimed at expanded interoperability of Flex Ethernet and increased data rates. The completed IAs—FlexE 2.0, FlexE Neighbor Discovery and Common ACO Electrical I/O—reinforce OIF’s work to provide the industry with solutions for flexible deployment and provisioning of network bandwidth.

“The completion of these projects reinforces OIF’s commitment to provide the industry with the flexibility and increased bandwidth solutions combined with increased data speeds it requires to keep up with market demands and drive solutions that enable the next generation of networks,” explained Dave Stauffer of Kandou Bus and OIF’s Physical and Link Layer (PLL) Working Group Chair.

FlexE 2.0

Initiated in 2016, the FlexE 2.0 project enables equipment to support new Ethernet connection types and FlexE allows network providers and operators to utilize optical transport network bandwidth in more flexible ways. FlexE can deterministically utilize the entire aggregated link, creating a more efficient alternative to the traditional IEEE 802.3ad or IEEE 802.1-based Link Aggregation (LAG) solutions which often can only utilize 70-80% of the available bandwidth. Key features of the FlexE 2.0 project include adding support for FlexE groups composed of 200GBASE-R and 400GBASE-R PHYs, in addition to groups composed of 100GBASE-R PHYs, and adding an option for the support of time and frequency synchronization at the FlexE group level.

FlexE Neighbor Discovery

The FlexE Neighbor Discovery project recognizes that FlexE capability discovery is still required to facilitate the setup of FlexE groups and clients. The project introduced some extensions to the Link Layer Discovery Protocol (LLDP) for FlexE capability discovery. It enables remote FlexE PHY and deskew capability discovery, PHY connectivity discovery and verifications, and FlexE Group subgroup integrity verification.

Common ACO Electrical I/O Project

The implementation agreement for Common Analog Coherent Optics (ACO) Electrical I/O follows the success of the CFP2-ACO optical transceiver implementation agreement but is form factor agnostic, so it also benefits analog coherent modules based on such form factors as CFP4, CFP8, QSFP, microQSFP, QSFP-DD and OSFP. The project defines the ACO electrical I/O independent of the choice of form factor and optical carrier count for 45 Gbaud and 64 Gbaud per-carrier applications.

“We recognize that the data center and communications industries require solutions for flexible deployment and provisioning of network bandwidth combined with component level interoperable infrastructure that can enable system capacity demands,” Stauffer continued.

OIF Day at CenturyLink

OIF Day at CenturyLink was held on October 16, 2018 in Littleton, CO. The interactive and educational workshop featured OIF and CenturyLink subject matter experts covering: OIF projects and directions including Networking Transport SDN work and an overview of Physical & Link Layer work.
