As optical fiber communication advances toward ultra-high-speed transmission, the G.654.E fiber has emerged as a core choice for next-generation trunk networks thanks to its ultra-low loss and large effective area. Nevertheless, its stringent splicing requirements have long been regarded as the touchstone for high-end splicing technology.With 20 years of in-depth dedication to the optical communication industry, Tumtec breaks the bottleneck with exquisite craftsmanship and sets a new benchmark. It takes the lead in launching the V9+ G.654.E Trunk Fusion Splicer, becoming the first established domestic manufacturer capable of stable splicing for G.654.E fiber. Driven by the explosive growth of 5G, artificial intelligence, the Internet of Things, high-definition video and other applications, G.654.E fiber is being deployed on a large scale in national trunk line. Riding this trend and drawing on 20 years of profound technological accumulation, Tumtec pioneered the launch of the V9+ G.654.E Trunk Fusion Splicer. Equipped with a self-developed 6-Motor core alignment system and intelligent algorithms, the device comes standard with a dedicated G.654.E splicing mode. Its measured splicing loss is stably controlled within 0.03dB, matching imported high-end models in core performance.  

SOC connector, full name Splice-on Connector, is also called a fiber thermal fusion connector or pre-polished fusion connector. It is a high-performance on-site termination solution that integrates the functions of a fiber optic connector and a pigtail into one unit. What is an SOC Connector? Simply put, it is a "connectorized pigtail", but its distinctive feature is that it comes pre-loaded with a short piece of optical fiber that has a factory-precisely polished ferrule. No on-site polishing or adhesive is required. During installation, the technician only needs to precisely fuse the pre-loaded short fiber with the field fiber cable inside the connector using a fusion splicer. What are the advantages of SOC connectors? Compared with traditional pigtail splicing (which requires additional splice protection sleeves and slack management), on-site polishing, or mechanical splicing, SOC connectors offer clear advantages: 1.High quality, low insertion loss 2.High reliability 3.High efficiency, space saving 4.More forgiving operation 5.High fault tolerance (multiple re-splicing attempts allowed) Types of SOC Connectors   SOC connectors can be classified in several ways according to your needs: By interface type: Primarily LC and SC. Other types such as ST, FC, and E-2000® are also available. By polish type: PC/UPC: Used for single-mode and multimode fiber, return loss typically ≥50dB. APC: Features an 8° angled end-face, mainly for single-mode fiber, greatly reduces ack reflection, return loss can reach up to ≥60dB. By applicable cable type: Supports various fiber types, such as 250μm bare fiber, 900μm tight-buffered fiber, 2.0mm and 3.0mm round patch cords, and 3.1×2.0mm butterfly drop cables. Applications of SOC Connectors   The high performance of SOC connectors covers almost all advanced fields of optical communications: Fiber access (FTTx) Data centers Enterprise networks & LANs Other specialized fields (aerospace, military, shipbuilding, medical, power plants, etc.)

Tumtec Team Conducts In-depth Exchange Visit to Partner NEXTEST in Brazil. Tumtec, alongside exclusive Brazilian distributor NEXTEST, achieved remarkable results at the ABRINT industry exhibition. Over the three-day event, their shared booth secured orders for over 100 units from local Brazilian buyers, a landmark leap for Tumtec’s fiber optic equipment business in Brazil.   At the joint Tumtec-NEXTEST booth, the local NEXTEST team showcased Tumtec’s flagship fusion splicers and test instruments to professional attendees, demonstrating product performance and localized service solutions live. The booth drew steady crowds of industry clients eager to learn about Tumtec’s robust gear for Brazil’s telecom infrastructure projects. Brazilian Engineers Speak Highly of Tumtec V3 & V9 at ABRINT. Two senior field engineers dropped by Tumtec & NEXTEST joint booth during ABFRENT Brazil Exhibition to test our flagship fusion splicer models V3 and V9. Having relied on Sumitomo and Fujikura splicing equipment for years in on-site construction, the engineers compared our machines through hands-on operation. They were deeply impressed by the excellent splicing efficiency: the 4-motor V3 delivers stable daily operation for regular projects, while the 6-motor V9 provides faster splicing speed for heavy-duty tasks. Compared with Japanese imported devices, Tumtec splicers maintain consistent reliable performance with much more competitive cost, perfectly matching the working scenarios of Brazil’s local optical fiber infrastructure projects.   The over 100 unit orders secured at ABFRENT Exhibition and favorable reviews from experienced field engineers fully demonstrate the outstanding competitiveness of Tumtec’s V3 and V9 fusion splicers. Building on this successful exhibition cooperation, Tumtec and NEXTEST will further coordinate regional marketing plans and technical support services, striving to deliver stable, high-efficiency and cost-saving fiber splicing equipment for Brazil’s fast-growing optical communication construction market.

In today’s Internet times, our daily life cannot be separated from the network. Mobile phones, computers, TVs, and all kinds of smart home devices all rely on the network to work properly. At present, most networks transmit data through optical fibers: data is first converted from electrical signals into optical signals, transmitted through optical fibers, and finally reaches thousands of households. To connect optical fibers in different transmission links, an optical fiber fusion splicer is required. It can connect many types of optical fibers, including drop cables, patch cords, pigtails, bare fibers, and so on. Optical fibers are made of extremely fine glass fiber, which is thin and brittle. Unlike electrical wires, they cannot be connected by twisting directly. To achieve a stable connection between two optical fibers, the two ends must be melted at high temperature and then spliced together. The working principle of the optical fiber fusion splicer is simple: it generates high temperature by releasing high voltage to instantly melt the ends of two optical fibers. With its precise alignment system, the two optical fibers are accurately aligned and fused together, realizing a seamless connection and ensuring smooth transmission of optical signals.
