ADVA targets access with its latest pluggable module

• The 25 gigabit-per-second (Gbps) SFP28 is self-tuning and has a reach of 40km
• ADVA’s CEO, Christoph Glingener, in his plenary talk at ECOC 2022 addressed the unpredictable nature of technology adoption.

ADVA has expanded its portfolio of optical modules with an SFP28 for the access market.

The AccessWave25 is a self-tuning dense wavelength division multiplexing (DWDM) pluggable.

The SFP28 is designed to enable communications service providers to straightforwardly upgrade their access networks from 10Gbps to 25Gbps.

ADVA made the announcement just before ECOC 2022.

ADVA and II-VI’s coherent partnership

• ADVA and II-VI have jointly developed a 100-gigabit coherent DSP
• Both companies plan to use the 2.0-2.5W, 7nm CMOS Steelerton DSP for a 100 ZR QSFP28 module
• II-VI’s ASIC design team engineered the DSP while ADVA developed the silicon photonics-based optics. 

ADVA and II-VI have joined forces to define a tiny coherent digital signal processor (DSP) that fits inside a QSFP28 optical module.

The Steelerton DSP can send a 100-gigabit dense wavelength-division multiplexing (DWDM) transmission over 80-120km, carrying wireless backhaul and access traffic.

“It is backhaul of broadband, it is backhaul of mobile, and it definitely moves outdoors,” says Christoph Glingener, CTO at ADVA.

The module also serves metro networks with its 300km reach using optical amplification.

II-VI and ADVA now join such established coherent players as Ciena, Huawei, Infinera, Nokia as well as Marvell, NEL, and Acacia, now part of Cisco.

Effect Photonics announced at OFC earlier this year its coherent market entry with its acquisition of the Viasat DSP team.
