Multimode Optical Coupler

 

Besides 1310nm and 1550nm fiber couplers, Fiberlink manufactures special couplers working at wavelength of 1480nm, 980nm, 1590nm, etc.These couplers use special single mode fiber, and the coupling ratio can be made on customer request. The products are Telcordia GR-1221-CORE qualified, and RoHS compliant.

• Specialized Wavelength & Custom Ratios

We offer couplers for unique wavelengths (1480nm, 980nm, 1590nm, etc.) beyond standard 1310/1550nm. With customizable coupling ratios (NX4/NX8 port options) and Telcordia GR - 1221 - CORE compliance, we meet niche needs for long - haul telecom, CATV, and high - speed LANs.

• Reliable Performance & Durability

Our couplers feature low excess loss, uniform power splitting, and rugged packaging. Built for excellent environmental/mechanical stability, they withstand harsh conditions-ideal for digital video systems and hybrid networks. No generic designs; we prioritize long - term reliability.

• Flexible Packaging & Tailored Solutions

From 3.0mm stainless - steel tubes to 900μm loose tubes (or 2mm/3mm cables), we offer diverse package dimensions and pigtail styles. Whether you need 250μm bare fiber or custom connectors (SC/UPC, etc.), we adapt to your project-no "one - size" limits.

 

 

Q1: Can you make couplers for wavelengths outside 850nm–1550nm?

A1: Yes! We support custom wavelengths. Specify your target range (e.g., 600nm–1700nm) in the ordering system-our "On request" option covers niche needs.

Q2: How to choose between 250μm bare fiber and 900μm loose tube?

A2: Bare fiber (250μm) suits compact, protected setups (e.g., indoor equipment). Loose tube (900μm) adds ruggedness for outdoor/harsh environments. Contact us to match your installation's mechanical demands.

Q3: Are hybrid video systems compatible with these couplers?

A3: Absolutely. Our couplers' uniform power splitting and low loss ensure stable signal distribution for digital, hybrid, and AM - video systems-tested for CATV and high - speed LAN reliability.
