V36 fiber optic splice protectors for 250 and 900 μm coated fibers
V36 SUPER LARGE fiber optic splice protectors are heat-shrink sleeves for 250 μm coated fibers and 900 μm buffered fibers. Their 3.6 mm recovered diameter and 1.2 mm steel reinforcing pin provide rigid splice protection for trays and cassettes with wider holders. Lengths from 45 to 68 mm protect the fusion splice against mechanical damage, moisture, and contamination.
Made in EU
V-Protect fiber optic splice protectors are manufactured in Poland. European origin, in-house production, and direct process control allow us to ensure consistency, flexibility, and fast product customization for OEM customers and integrators.

DETAILED TECHNICAL DESCRIPTION
V36 SUPER LARGE fiber optic splice protectors were developed for splice trays, cassettes, and fiber optic closures with holders designed for very large-diameter protectors. The construction protects fusion splices of 250 μm coated fibers or 900 μm buffered fibers against mechanical damage, contamination, and climatic conditions without introducing additional optical power loss.
The V36 Series has a 3.6 mm recovered outer diameter and is available in lengths from 45 to 68 mm. Each protector consists of a 1.2 mm steel reinforcing pin, a thin-wall outer tube, and an inner tube with a 1.4 mm opening. The hot-melt inner layer fills the space around the fiber and pin, reducing the risk of air bubbles. Products are checked against EN 50411-3-3, Telcordia GR-1380-CORE, and ZN-96 TPSA-006 requirements.

V36 SPLICE PROTECTORS – FREQUENTLY ASKED QUESTIONS
V36 SUPER LARGE protects fusion splices of single fibers with a 250 μm coating or 900 μm buffer. The hole diameter before recovery is 1.4 mm.
The recovered outer diameter is 3.6 mm ±0.2 mm. Lengths range from 45 to 68 mm, with a 1.2 mm steel reinforcing pin.
Match the protector length and recovered diameter to the holder in your splice tray. Check the dimensions in the table before ordering.
Yes, provided the closure contains splice trays with holders suitable for the 3.6 mm recovered diameter and selected length.
The maximum shrinking time is 60 seconds and the minimum installation temperature is 110 °C. Select a heater program suitable for the protector and follow the equipment manufacturer’s instructions.
Yes. Solid and transparent colors are offered. Check the availability of each length and color in the Fotech store or contact the manufacturer.
Click the red cart in the required row. Empty shop cells for 55, 60, 65 and 68 mm indicate that no corresponding store product has been confirmed.
Standard packaging is 100 protectors per zip bag and 1000 per outer box. Other packaging options are available on request.
Yes. Custom markings, packaging, colors and lengths can be agreed as part of OEM and private-label projects.
V36 has a 3.6 mm recovered diameter, while V32 has a 3.2 mm recovered diameter. Both series use a 1.2 mm steel reinforcing pin, have a 1.4 mm opening and support 250 μm and 900 μm fibers. V36 fits trays that require a larger protector diameter.
