Leviton OPT-X SDX 12-Fiber MTP-to-LC Cassettes — Singlemode & Multimode Available
Upgrade or expand your structured fiber network with Leviton OPT-X SDX fiber cassettes. These pre-terminated 12-fiber cassettes convert one MTP/MPO trunk connection into six LC duplex ports — enabling rapid, high-density fiber deployment in data centers, server rooms, and enterprise networks.
Both models use Method B polarity and fit any standard Leviton OPT-X SDX 1RU or 4RU fiber enclosure. Plug-and-play design eliminates field splicing — simply snap the cassette into your enclosure and connect.
- 12 fibers per cassette — 1× MTP/MPO (rear) to 6× LC Duplex (front)
- Method B polarity — industry-standard straight-through
- Compact SDX form factor — up to 72 LC fibers per 1RU
- Pre-terminated & factory tested — guaranteed low insertion loss
- Compatible with Leviton OPT-X SDX enclosures and patch panels
- Ideal for data center, enterprise, campus, and SAN/LAN environments
