Couplers, Splitters & Combiners
NxM (N = 1–8, M = 4–32) Single Mode Broadband Splitter Module
The N×M Fiber Couplers/Splitters are fabricated by cascading 2×2 fused fiber couplers in a star or tree architecture, providing low insertion loss, excellent channel-to-channel uniformity, high optical power handling, and high polarization extinction ratio for polarization-maintaining (PM) versions. The design offers industry-leading performance over an exceptionally wide operating wavelength range from 370 to 2400 nm and a broad operating temperature range of −40 °C to +150 °C. Standard and custom port configurations are available to meet specific application requirements. Please note that optical couplers, when used as combiners, inherently introduce losses. For example, combining two signals with a 50:50 coupler results in approximately 50% optical loss at each input. We produce a family of fiber combiners with minimal excess loss.

System integration
Integration and compatibility
Use these checks to connect NxM (N = 1–8, M = 4–32) Single Mode Broadband Splitter Module to the surrounding optical, mechanical and control system. Every value shown is taken from this model's own specification record.
- Optical interface and fiber
- Fiber Type: SMF-28, PM1550, 50/125 · Fiber Length: 0.5m, 1m, 2m
- Specify connector polish and fiber architecture together. FC/PC, FC/APC and SMA interfaces, and single-mode, multimode and polarization-maintaining fibers, impose different return-loss, mode-field and alignment requirements.
- Wavelength and loss budget
- Wavelength: 980, 1060, 1310, 1480, 1550, 2000, 400, 450, 520, 650, 750, 850
- Check the Couplers, Splitters & Combiners passband, insertion loss, return loss and power handling at the actual source wavelength; a nominal telecom-band label is not a substitute for the configured range.
