IPG Photonics business Menara Networks of Dallas, TX, USA (a vertically integrated provider of IP/Ethernet DWDM transport solutions) is now sampling its coherent CFP2-DCO transceivers to selected customers.
Based on a 16nm coherent processor, the digital CFP2-DCO ‘system-in-a-module’ provides complete DWDM coherent transmission for 100G and 200G per wavelength in a CFP2 MSA small form factor. It performs all necessary adaptive PM-QPSK and PM-QAM 16 modulation, digital signal processing for linear and non-linear fiber impairments compensation, G.709-compliant OTN framing, and a multitude of hard and LDPC-based soft decision forward error correction (FEC) encoders/decoders. Compatible with 100GE, CAUI, OTL4.10 and OTL 4.4 interfaces, Menara’s coherent CFP2-DCO is full C-band tunable and supports ITU-T G.694.1 6.25GHz flexible grid. With maximum versatility, it enables ZR, data-center interconnection, metro and long-haul applications.
“Building on a long track record of bringing high-performance optical modules with advanced functionalities to the market, Menara’s engineering team successfully integrated all necessary functions for digital coherent transmission in a CFP2 form factor,” says chief technology officer & VP of engineering Salam ElAhmadi. “CFP2’s smaller foot-print not only doubles the faceplate density but also improves 200G coherent transmission economics.”
Menara is showcasing its Hytham line of digital coherent modules live on a 200km repeater-less fiber link featuring IPG Photonics Corp’s compact hybrid EDFA/Raman Optical Services Transport Platform (OSTP) in booth #4423 at the Optical Networking and Communication Conference & Exhibition (OFC 2018) in San Diego (13-15 March). Also showcased live is the firm’s Atlas line of full C-band tunable, industrial-temperature-grade 10G SFP+ and XFP modules with integrated OTN framing and FEC based on its proprietary application-specific integrated circuits (ASICs).
