从China供应商批发进口1550nm 1x2 Pm Optical Fused Coupler — FOB条款

This 1550nm 1x2 Polarization Maintaining (PM) Optical Fused Coupler from Ruik-Tech Communication Co.,LTD. in Dongguan, China, is built by fusing and tapering PM Panda fibers to split or combine optical signals with minimal loss. It operates at a center wavelength of 1550nm with an operating bandwidth of ±15nm. For a P-grade unit, the maximum excess loss is 0.7dB, the minimum extinction ratio is 20dB, and the splitting ratio tolerance for a 50/50 split is ±4.8%.

The coupler's construction provides a rugged and compact solution, with package dimensions of either Ø3x54mm for bare fiber with 0.9mm loose tube, or 90x20x10mm for loose tube diameters of 0.9mm, 2.0mm, or 3.0mm. It handles a maximum continuous wave optical power of 3W and functions reliably across an operating temperature range of -5°C to +75°C. The device offers a minimum directivity of 50dB and a maximum return loss of 55dB, ensuring signal integrity.

Engineers source this coupler for coherent communication systems, power monitoring setups, and fiber sensor networks where maintaining polarization is critical. Buyers should specify their required splitting ratio (available from 50/50 to 1/99) and tolerance grade (P or A) when ordering. Confirm the exact package dimension and loose tube size with Ruik-Tech to match your system's physical integration requirements.

Ruik-Tech Communication Co.,LTD. is an optical passive component manufacturer based at Floor 4, Building A, Zhaohe Industrial Park in Dongguan, China. The company's production is backed by an ISO9001:2015 certification, which governs their quality management processes. Their core expertise lies in high-power components (up to 100W for isolators) and a broad range of polarization-maintaining fiber components for wavelengths from 780nm to 2000nm.

The supplier's stated application sectors include fiber lasers, sensing, CATV, telecommunication, medical systems, and gyroscopes. While the listing profile identifies a 'harbor' trust tier and a 0.00% response rate, direct inquiry is necessary to obtain current information on minimum order quantities, production lead times, and custom configuration options for this fused coupler.
