About UCL Swift


Founded as a high-precision tools manufacturer in 1982, UCL Swift launched the first optical fiber termination products in 1999 to meet customers’ needs for reliable and productive solutions. Since then, UCL Swift North America has developed and introduced innovative and dependable products for processing and splicing optical fibers. 


As a preeminent leader in our industry, in 1999, we launched the first optical fiber termination products. Since then, UCL Swift has also engineered strippers, cleavers, multipack, core alignment splicers, clad alignment splicers integrated with thermal auto stripper and cleaver, Splice-On Connector (SOC) and many other related accessories. 

Successfully launched in 2007, the core alignment optical fiber fusion splicer, the Keyman S1, ignited the world market with the highest competitiveness in its reliability, efficiency and price. 

UCL Swift North America is a leading world supplier of 8 degree angled cut cleavers for optical fibers. Thanks to its superior performance, this innovative cut cleaver is globally renowned. 

In 2010, Swift F1, a state-of-the-art FTTH mini Fusion Splicer (including thermal auto stripper, single-action cleaver, air-pump cleaner, clad alignment splicer and sleeve oven integrated into a tiny unit), together with simple and easy-to-assemble low-cost Fusion Splice-On Connectors (FSOC), was launched. The efficiency and affordability of the Swift F1 splicer and its Splice-On Connector (SOC) for high-speed is FTTH networks is unparalleled.

Today, UCL Swift North America remains committed to excellence and innovation. As a result, we built a line of revolutionary All-In-One fusion splicers that integrate thermal stripping, cleaving, cleaving, splicing and sleeving into one convenient unit, reducing installation time and improving connection reliability. 

The Swift KF4A is an advanced All-In-One Active Cladding Alignment splicer that eliminates the most common fatal issues with conventional mechanical connectors, including low quality, weak durability and high maintenance costs. 

As we continue to meet the growing fiber optic demands of the 21st century, UCL Swift developed the new Swift KR12A Ribbon splicer and the new Swift K33A IPAAS Core Alignment splicer. The KR12A offers our All-In-One system and is the ideal solution for campus, building and datacenter backbone applications where high fiber counts are required. The K33A also offers our All-In-One system and is ideal for medium and long-range optical circuits, LAN, CATV, FTTx.
