Company Profile

High Power Polarization Maintaining Isolator Dual Stage 1550nm 900μm Fiber

The polarization-maintaining isolator including 1030 1040 1050 1053
1060 1064nm 1310nm 1480nm 1550nm or others, it is a passive optical
device that allows only one-way light to pass through. It uses
panda polarization-maintaining fiber and maintains the input light
polarization with a high extinction ratio. Polarization maintaining
fiber isolators are usually used to protect lasers or amplifiers
from back-reflected light. Unifiber provides single stage and dual
stage isolator with different isolation levels to meet customer
parameter requirements for different scenarios through different
cost performance. In addition, it also provides customized services
for high-power products.

Features

High Isolation
Low Insertion Loss
High Return Loss
