Description
Overview
The Sumitomo T-55 Fusion Splicer is a core alignment fusion splicer designed for fiber contractors, OSP technicians, and FTTx deployment teams requiring a compact, field-capable splicer with automatic arc calibration and multi-fiber type support. It uses a 3-axis core alignment system and an integrated tube heater, supporting SM, MM, DS, and NZDS fiber types with a splice cycle of approximately 6 seconds. This Grade C unit from OMIWAA provides access to a fully functional Sumitomo T-55 at a significantly lower cost than comparable new or near-new units, with an arc count of 6,434 — low for a used splicer in this class — indicating substantial remaining service life under normal operating conditions.

Condition Report
This unit is graded C — Fair. It is fully functional and was tested prior to listing — splice and heat shrink cycles were observed to operate within expected parameters during inspection. Visible surface wear and handling marks are present on the exterior casing, consistent with regular professional field deployment. The arc counter reads 6,434 arcs, which is low relative to the service life typical of a used unit in this class. No electronic faults or alignment issues were identified during inspection. Buyers are advised to review the provided photographs to assess the cosmetic condition prior to purchase.
Included in the Box
- Sumitomo T-55 core alignment fusion splicer (main unit)
- Rechargeable battery pack

Why Buy From Omiwaa
OMIWAA physically receives, inspects, grades, photographs, and documents every unit before it is listed for sale. This Sumitomo T-55 was handled directly by OMIWAA — it was not sourced through a broker, listed on consignment, or drop-shipped from a third party. OMIWAA owns and ships every item in its inventory, and condition grading is based on direct physical assessment, not seller-reported information.
Common Use Cases
The Sumitomo T-55 is used across a range of professional fiber optic deployment and maintenance applications where core alignment precision and field portability are required.
- FTTx and FTTH construction requiring consistent singlemode splicing with automatic arc calibration across variable field conditions
- Outside plant splicing in aerial, buried, and duct environments where IP52 protection and shock resistance support reliable field operation
- Backbone and distribution fiber splicing for telecom operators and network integrators working across SM, MM, DS, and NZDS fiber types
- Fiber restoration and emergency repair where a compact, battery-operated core alignment splicer reduces deployment time on-site
