Tellabs 82.71532‑110‑R5 – 110 km Dispersion Compensation Module (DCM)

Tellabs 82.71532‑110‑R5 is a dispersion compensation module (DCM) designed for long‑haul optical fiber networks. This telecom‑grade optical module counteracts chromatic dispersion in single‑mode fiber (SMF), helping maintain signal integrity over extended distances up to 110 km. It is typically used in Tellabs optical transport systems and compatible SONET/SDH/OTN platforms to improve optical performance in high‑capacity fiber links. These modules are often sold used or refurbished and are essential in optical backbone transport infrastructure where dispersion management is required.
