OIF begins work on 112G-Extra Short Reach (XSR)+ project

 OIF has initiated work on a new Common Electrical I/O (CEI) 112G Extra Short Reach (XSR)+ project that will allow lower power, multi-source 112Gbps (optimized for 106.25Gbps) electrical I/O interface to be developed with advanced PCB and substrate technology. The project will also support an open ecosystem based on Near Package Optics (NPO) architecture. OIF members are proposing that an “XSR+” type interface is used to add reach for NPO applications over the existing XSR interface to enable a multi-vendor open ecosystem without adding significant power.

During OIF’s Q3 2021 Technical and MA&E Committees Meeting, held virtually August 2-6, two projects under the Physical and Link Layer (PLL) newly formed Management track were also initiated. The first project will transition ownership and maintenance of the Common Management Interface Specification (CMIS) from the Quad Small Form Factor Pluggable Double Density (QSFP-DD) Multi-Source Agreement (MSA) to OIF. 

The second project will focus on CMIS extensions for co-packaging implementations.


“Our quarterly meetings provide a critical platform for our members to discuss and debate interoperability challenges and industry standards that help OIF continue its mission to accelerate industry innovation,” explained David Stauffer, OIF Physical & Link Layer WG Chair and Kandou. “The new CEI-112G-XSR+ project will help strengthen an open ecosystem for NPO demonstrating OIF’s leadership in next-generation channel definition. Another significant new activity that addresses industry interoperability and standards is OIF’s new Management track. Due to the complementary/synergistic nature of the work with the OIF co-packaged optics, NPO, CEI and coherent optics projects, OIF will take over the ongoing CMIS revisions as well as further enhancements and CMIS extensions under this track.”

In addition, Rob Stone of Facebook was appointed to the OIF Board of Directors, filling an open position. Stone will serve the term for this position that goes through September 2022.

IEEE adopts MIPI A-PHY spec for automotive networks

The MIPI A-PHY v1.0 specification, which is the first asymmetric, long-reach, serializer-deserializer (SerDes) physical layer interface for automotive applications has been adopted as an IEEE standard. 

The MIPI Alliance said applications for MIPI-APHY are expected to include bridges for advanced driver assistance systems (ADAS), autonomous driving systems (ADS) and in-vehicle infotainment (IVI). With a reach of up to 15 meters, MIPI A-PHY (and now also IEEE 2977) provides an asymmetric data link in point-to-point or daisy-chain topologies, with high-speed unidirectional data, embedded bidirectional control data, ultra-high noise immunity and optional power delivery over a single cable. It also offers an ultra-low packet error rate of 10‑19 for unprecedented performance over the vehicle lifetime, ultra-high immunity to electromagnetic interference (EMI) effects in demanding automotive conditions and data rate as high as 16 Gbps, with a roadmap to 48 Gbps and beyond. A-PHY also serves as the foundation of the MIPI Automotive SerDes Solutions (MASS) framework, which simplifies the integration of cameras, sensors and displays across a vehicle while adding functional safety and security. 

“This is the first time MIPI has sought adoption by another standards body for one of our specifications," said Joel Huloux, chairman of MIPI Alliance. "With the approval of IEEE 2977, MIPI A-PHY becomes accessible to a broader network of system engineers beyond the MIPI membership. This promises a tremendous expansion of the ecosystem of expertise around A-PHY, which will translate into greater interoperability, vendor choice and economies of scale for the global automotive industry, as well as users of the specification from other application spaces such as the IoT (Internet of Things) and industrial.”

OIF publishes results of Transport SDN API interoperability demo

OIF published the results of its 2020 Transport SDN Application Programming Interface (API) Interoperability Demonstration, which was a ten-week long interoperability testing exercise that was held in Telefonica’s lab in Madrid.

The interoperability testing involved three phases over ten weeks, Sept – Nov 2020:

  • Phase 1: Open Networking Foundation (ONF) T-API NBI testing, Scope: ONF T-API v2.1.3 reference implementation agreement TR-547
  • Phase 2: Open terminals testing including discovery, provisioning, service de-activation and streaming telemetry
  • Phase 3: End-to-end disaggregation demo, Scope: evaluation and demonstration of end-to-end use cases

Findings and results of the testing include:

  • Vendor products demonstrate a high level of maturity and support of operator-favored use cases, based on T-API version 2.1.3 and OpenConfig APIs. Vendors have adopted the ONF 2.1.3 Reference Implementation Agreement (ONF TR-547) rapidly and with few deviations.
  • Inconsistent interpretation of the Internet Engineering Task Force (IETF) RESTCONF standard was one interoperability issue identified, especially standard authentication. Clarification to RESTCONF provisioning behavior and implementation scalability were also identified as issues.  
  •  A particularly good level of compliance to the OpenConfig models was demonstrated by implementations, however, some areas such as key exchange algorithms for IETF NETCONF and complex use cases for device provisioning and commissioning did generate issues.


Participating vendors included ADVA, Ciena, Cisco Systems, Infinera and Nokia. Network operator Telefónica hosted the demo. China Telecom, Telia Company and TELUS participated as consulting network operators.

“Interoperable transport SDN APIs are essential capabilities to enable open optical networks,” said Mauro Costa, Head of planning, strategy & architecture, Telia Company, a consulting network operator for this year’s demo. “International co-operations, like this one with OIF, allow the industry to progress at a high pace and Telia Company welcomes the opportunity offered by this interoperability demo. It reinforces that we are advancing in the right direction and that the maturity of the APIs implementation for optical SDN architecture is improving.”

MIPI RFFE v3.0 offers tighter timing precision for 5G

The MIPI Alliance released an updated version of its standard interface for control of radio frequency (RF) front-end (FE) subsystems.

MIPI RFFE v3.0 is designed to deliver tighter timing precision and reduced latencies need for 5G.

The MIPI Alliance said that since its initial release a decade ago, RFFE has been deployed in billions of devices—in virtually every device with cellular connectivity—including handsets, smartwatches and automobiles, to name a few.

MIPI RFFE simplifies the design, configuration and integration of the increasingly complex RF front end—which encompasses the power amplifiers, antenna tuners, filters, low-noise amplifiers (LNAs) and switches—connecting with the modem baseband and/or RF integrated circuit (RFIC) transceiver. As the number of RF bands involved in both uplink and downlink communications has exploded in the rollout of 5G, the subcarrier spacing (SCS) windows among RF packets have narrowed. MIPI RFFE v3.0 addresses the decreased reconfiguration windows and lower-latency switching among various bands and band combinations demanded in the 3GPP 5G standard by delivering enhanced triggering features and functionality, which results in fast, agile, semi-automated and comprehensive control of individual RFFE subsystems.

MIPI RFFE v3.0 utilizes multiple, complementary triggers to synchronize and schedule changes in register settings, either within a slave device or across multiple devices:

  • Timed triggers—Allows for tighter, synchronized timing control of multiple carrier aggregation configurations
  • Mappable triggers—Enables groups of control functions to be remapped to other triggers quickly and easily
  • Extended triggers—Boosts the number of unique triggers available in the RF control system and accommodates increasingly complex radio architectures
  • With the enhanced triggering functions, MIPI RFFE v3.0 improves throughput efficiencies and reduces packet latency, while also improving the precision in trigger placement. For back-to-back triggering operations, for example, the specification delivers a 20x improvement in timing precision.

“The new version of the specification expands its applicability to 5G use cases beyond mobile, such as for automotive, industrial and the Internet of Things (IoT),” said Joel Huloux, chairman of MIPI Alliance. “Development of MIPI RFFE v3.0 was laser focused on satisfying the unprecedented requirements for tight timing precision and low latency in the 3GPP 5G standard today. In this way, the specification helps ensure that manufacturers’ 5G devices deliver the high-performance RF capabilities necessary to enable critical consumer and business features in emerging 5G application spaces.”

“With MIPI RFFE v3.0, the specification has been streamlined and optimized to deliver the specific capabilities required to thrive in today’s 5G rollout across the Frequency Range 1 (FR1) of traditional sub-6 GHz cellular bands,” said Jim Ross, MIPI RF Front End Control Working Group Chair. “The working group is always looking to refine the specification to continue differentiating and benefitting our user community, and we welcome engagement in requirements gathering for Frequency Range 2 (FR2) and the ongoing evolution of the next-generation MIPI RFFE for the subsequent stages of 5G deployment.”
