980/1550nm WDM

Description

The 980/1550nm-pumped WDM is used specially in C-band Erbium Doped fiber Amplifiers(EDFA). This kind of WDMs can enable the combination of 980nm pump laser and 1550nm optical in Erbium Doped fiber to amplify. Fused 980/1550nm WDMs are designed with the special optical fiber.they have high isolation and good performance in applications.

Features

Low Insertion Loss
High Isolation
Low PDL
Good Directivity
Good Environmental Stability

Applications

EDFA
Optic-fiber CATV
WDM System
