The LIGHTech LT3000 series delivers fully customizable optical switching in a rugged 2 U chassis. This X2MB1618MDG-SSS2 configuration provides a mixed single-mode and multi-mode switching matrix, local and remote control, and ultra-low insertion loss—ideal for automated fiber-optic test benches, R&D labs, and manufacturing environments.
Key Features
- Flexible custom 16×18 switching architecture (mixed SM/MM)
- Local front-panel keypad plus GPIB and RS-232 remote control interfaces
- Motorized, latching actuation for reliable repeatability
- Ultra-low insertion loss: ≤3 dB for 1×16 SM path and ≤1 dB for each 1×2 MM path
- FC/APC bulkhead connectors on rear panel for quick field mating
- Bench-top or 19″ rack-mount (2 U height, 21″ depth)
- Wide wavelength windows: 1310/1550 nm (SM) and 850/1300 nm (MM)
- Robust steel chassis with EMI shielding and thermal management

- Automated fiber-optic manufacturing test systems
- Transmitter/receiver performance validation
- OTDR switching for loss and reflectance mapping
- Telecom and data-center fiber link qualification
- R&D laboratories developing custom optical components
Workflow Integration
- Combine with Viavi T-BERD/MTS platforms for end-to-end fiber validation
- Script multi-port switching sequences over GPIB/RS-232 to accelerate batch testing
- Pre-label channels and use ASCII-based control macros to minimize operator errors
- Integrate into PXI or LXI-based test benches for hybrid electrical/optical DUT verification
Customization & Expandability
- Add VOA arrays, fiber taps, or extra switch banks as demand grows
- Upgrade to 4 U or 8 U chassis frames for higher port counts
- Field-installable module slots simplify swapping between SM and MM modules
