Mux / Demux / PON
High-Performance DWDM/CWDM, OLT/ONT, and SmartPluggable Optical Systems
Open, Scalable Optical Transport for Modern Networks
The MobStack series brings carrier-grade DWDM/CWDM multiplexing, OLT/ONT access innovation, and SmartPluggable amplification into a single disaggregated, SONiC-compatible ecosystem. Designed for operators who need to extend reach, maximize fiber utilization, and simplify deployment — without vendor lock-in.
- Vendor-neutral, SONiC and Whitebox compatible
- Passive to active optical solutions in one portfolio
- Field-proven for DCI, metro, and long-haul environments
- Compact, modular form factors for rapid deployment
Featured Products
Three purpose-built product lines covering every layer of the optical network — from passive multiplexing to active PON access and embedded SmartPluggable optics.
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 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 provisioning
- Extended temperature options
Applications
- Dynamic wavelength allocation
- DCI and metro edge deployments
- Multi-vendor open optical systems
OTN 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.
Client Interface 1G to 400G
Integrated EDFA and DCM options with built-in OEO regeneration for reach extension beyond standard limits.
OTU1/OTU2/OTU4 Framing
Modular hot-swappable architecture with web and SNMP management and 1+1 protection switching.
Long-Haul & Metro Transport
Inter-data center and backbone connectivity with optical signal regeneration and dispersion management.
Scalable Aggregation
Purpose-built for carriers and enterprises who need scalable optical aggregation with investment protection.
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 or ONT-in-a-stick (SFP+)
- ITU-T G.984, G.987, G.9807 compliant
- Built-in MAC and PHY for standalone use
- SNMP and OMCI remote management
- Optional dual PON / Combo optics
Applications
- FTTH and FTTB deployments
- Edge aggregation for mobile and enterprise
- Compact OLT at access nodes
- Rapid PON expansion on open platforms
SmartPlugs
Built for Whitebox and SONiC platforms, SmartPlugs integrate amplification, monitoring, and multiplexing directly into the optical path — eliminating external chassis and enabling a fully software-defined optical edge.
SmartPlug QSFP-EDFA
- Compact EDFA in QSFP form factor
- Extends DWDM reach up to 40 dB link budget
- Automatic Gain Control (AGC) with CMIS monitoring
- Ideal for long-reach DCI and open optical transport
SmartPlug QSFP-OTDR
- Built-in OTDR for live fiber diagnostics
- Detects reflections, loss, and faults in real time
- Remote visibility through standard management
- Reduces MTTR and improves SLA compliance
SmartPlug MUX & Splitter
- 4CH or 8CH DWDM MUX/DEMUX in optical cable
- 100 / 200 / 300 GHz channel spacings (C-Band ITU)
- Low insertion loss and high isolation
- Perfect for AI clusters and field muxing
