Mux/Demux/PON
High-Performance DWDM/CWDM, OLT/ONT, and SmartPluggable Optical Systems
Open, Scalable, and Reliable.
Our MobStack series delivers flexible, carrier-grade optical transport solutions engineered for modern open networks. We combined DWDM/CWDM multiplexing, scalable 1–400G ONT transport, and SmartPluggable modules to help operators extend reach, optimize fiber usage, and simplify deployment — all within a disaggregated, SONiC-compatible ecosystem.

DWDM & CWDM Mux/Demux
MobStack DWDM and CWDM MUX/DEMUX modules let multiple optical channels share a single fiber pair, dramatically increasing bandwidth without deploying new fiber. Each unit offers ultra-low loss, high isolation, and flexible packaging to fit any environment.
Key Features
- Passive, maintenance-free operation
- Up to 48 DWDM or 18 CWDM channels
- Optional OSC and OTDR monitoring ports
- Typical insertion loss ≤ 1.5 dB
- LGX, Mini-ABS, or 1U rackmount
Applications
- Data Center Interconnect (DCI)
- Metro and backbone DWDM expansion
- Enterprise dark fiber and private backbones
- 5G transport and mobile backhaul
DWDM Transceivers
Our 10G and 25G tunable or auto-tunable DWDM transceivers complement MobStack’s MUX/DEMUX modules to simplify DWDM provisioning. They allow dynamic wavelength selection or automatic tuning, reducing the need for inventory-heavy channel-specific optics.
Key Features
- 10G and 25G SFP+/SFP28 tunable optics
- Plug-and-play ITU-T grid alignment
- Simplifies logistics and accelerates provisioning
- Extended temperature options for outdoor use
Applications
- Dynamic wavelength allocation
- DCI and metro edge deployments
- Multi-vendor open optical systems
ONT Series
Combining multiplexing, EDFA/DCM amplification, OEO regeneration, and advanced FEC error correction into a single modular platform to ensure efficient long-distance performance and flexible service delivery.
Key Features
- Client interface support from 1G to 400G
- Integrated EDFA and DCM options
- Built-in OEO regeneration for reach extension
- Advanced FEC for improved error performance
- OTU1/OTU2/OTU4 framing and multiplexing
- Modular, hot-swappable architecture
- Web and SNMP management with 1+1 protection
Applications
- Long-haul and metro optical transport
- Inter-data center and backbone connectivity
- Optical signal regeneration and dispersion management
- Scalable aggregation for carriers and enterprises
PON Transceivers
OLT & ONT in a Stick
MobStack extends optical innovation to the access layer with ECIN PON transceivers, including OLT-in-a-stick and ONT-in-a-stick solutions. These compact, pluggable modules integrate the full functionality of a traditional OLT or ONT directly into an SFP/SFP+ form factor, simplifying fiber access for open broadband and mobile edge networks.
Key Features
- Supports GPON and XGS-PON
- OLT-in-a-stick (SFP+ OLT) or ONT-in-a-stick (SFP+ ONT)
- ITU-T G.984, G.987, and G.9807 compliant
- Built-in MAC and PHY for standalone operation
- Plug-and-play into Whitebox switches or routers
- SNMP and OMCI remote management
- Optional dual PON / Combo optics
Applications
- FTTH and FTTB deployments
- Edge aggregation for mobile and enterprise
- Compact OLT deployment at access nodes
- Rapid PON expansion on open platforms
SmartPlugs
Optical Intelligence for Whitebox & SONiC Switches
Built for Whitebox and SONiC platforms, our SmartPlugs integrate amplification, monitoring, and multiplexing directly into the optical path — eliminating external chassis and enabling a fully software-defined optical edge.
