Coherent has introduced a family of single-mode fibers for the 1310–1620 nm telecom band, aimed at miniaturized optical components. The company said the fibers are designed to address optical transmission in compact packages through tight geometric consistency, controlled cutoff wavelengths and disciplined manufacturing processes.
Coherent designed the single-mode fiber series around production concerns for component manufacturers. High core-to-clad concentricity and uniform geometry are intended to reduce splice loss and support consistent optical connections across assemblies.
Tight tolerances for second-mode cutoff wavelength and optimized bend-radius specifications make the fibers suited to miniature optical device packaging, the company said. Those characteristics are intended to translate into higher component reliability, improved production yields and lower overall manufacturing costs in couplers, optical switches and related devices.
The product family includes three listed models, all specified for the 1310–1620 nm operating range. Two models use an 80.0 ± 1.0 μm cladding diameter, while one uses a 125.0 ± 1.0 μm cladding.
| Model | Operating wavelength range | Cladding diameter |
|---|---|---|
| 1310-HP-80 | 1310 – 1620 nm | 80.0 ± 1.0 μm |
| 1310M-HP | 1310 – 1620 nm | 125.0 ± 1.0 μm |
| 1310M-HP-80 | 1310 – 1620 nm | 80.0 ± 1.0 μm |
The fibers are available in 80 μm and 125 μm cladding diameter options to accommodate different packaging limits. Their operating temperature range spans -55 to 85 °C, according to the specifications, covering a variety of demanding industrial environments.
The products carry a prooftest level of at least 200 kpsi (1.4 GN/m²), a mechanical screening measure intended to support long-term reliability. Coherent said the combination of optical performance and mechanical robustness is intended for harsh industrial applications.
