Fiber Optic Splicing Services
iFiber Optix performs fiber optic splicing services in-house, with our own certified technicians handling every job directly — no subcontracting. Based in Tustin, we provide fusion and mechanical splicing across California for data centers, carrier networks, and enterprise infrastructure. Whether you need fusion splicing for permanent, ultra-low-loss connections or mechanical splicing for rapid field deployment, our technicians deliver factory-quality results on every job — from hyperscale data centers and carrier-grade telecom networks to enterprise campus infrastructure.
Our splicing services support both singlemode (OS1/OS2) and multimode (OM1–OM4) fiber types, with splice loss consistently below 0.1 dB on fusion splices, well within IEEE 802.3ae compliance requirements. Every splice is OTDR-verified and fully documented before handoff.
What Is Fiber Optic Splicing?
Fiber optic splicing is the process of permanently joining two fiber optic cables end-to-end to create a continuous, low-loss optical path.
Unlike connectors — which can be plugged and unplugged — a splice is a fixed, permanent connection used wherever the signal path must be continuous with minimal loss: feeder cable runs, outside plant closures, backbone distribution points, and anywhere a broken or extended cable needs a seamless join.
There are two primary splicing methods. Fusion splicing uses an electric arc at approximately 3,000 °C to permanently weld two fiber ends together — achieving insertion loss below 0.05 dB and representing the gold standard for permanent infrastructure. Mechanical splicing uses a precision alignment sleeve and index-matching gel to hold fiber ends in contact without heat, enabling faster field deployment for emergency restorations and temporary links.
iFiber Optix offers both methods, backed by OTDR verification and full splice loss documentation on every project.
The Fusion Splicing Process
Walk through every step of a fusion splice — from stripping the fiber to loading the finished splice into a cassette tray.

Key Features of Our Fiber Optic Splicing Services
- Fusion Splicing: Ultra-Low Loss Our fusion splicing service uses precision arc-fusion equipment to permanently weld two fiber ends together, achieving typical splice loss below 0.05 dB on singlemode fiber. Ideal for long-haul telecom runs, backbone infrastructure, and any application where signal integrity is critical. Every fusion splice is protected with a heat-shrink sleeve and OTDR-verified before handoff.
- Mechanical Splicing: Fast Field Deployment Mechanical splicing provides a quick, reliable connection without arc fusion equipment — the preferred choice for emergency restorations, temporary links, and remote field locations. iFiber Optix mechanical splices deliver consistent insertion loss below 0.5 dB, meeting the needs of both multimode and singlemode applications.
- OTDR Testing and Full Documentation Every splice point is verified using Optical Time Domain Reflectometry (OTDR), providing a complete trace of each fiber link. Customers receive full splice loss reports and OTDR traces — documentation your engineering team needs for network records, warranty support, and future troubleshooting.
- Singlemode and Multimode Capability Certified to splice all common fiber types including OS1, OS2 singlemode and OM1, OM2, OM3, OM4 multimode, across loose tube, tight buffered, ribbon fiber, armored cable, and aerial plant constructions.
Benefits of Choosing iFiber Optix for Fiber Splicing
- Certified Technicians All iFiber Optix splicing technicians are trained and certified in both fusion and mechanical splicing techniques, ensuring every project meets the highest industry standards for performance and reliability.
- Minimal Network Downtime Our efficient splicing workflows and fully equipped field teams minimize network disruption. Whether you're restoring a cut fiber or adding capacity to a live network, we work quickly without compromising splice quality.
- Verified Performance on Every Job We do not consider a job complete until every splice has been OTDR-tested, loss values confirmed, and results documented. You receive full test reports with every project — the same standard we hold ourselves to on every installation.
- Scalable for Any Project Size From a single emergency splice restoration to a multi-site, high-fiber-count infrastructure deployment, iFiber Optix has the equipment, personnel, and logistics to scale with your project requirements, on time and on budget.
Fiber Optic Splicing Applications
01
Data Centers
High-density data center environments demand precise, low-loss fiber connections supporting 10G, 40G, 100G, and 400G applications. Our fusion splicing delivers sub-0.1 dB performance for modern data center interconnects, with full OTDR documentation for every link.02
Telecommunications Networks
Carrier-grade networks cannot tolerate high splice loss or unreliable connections. iFiber Optix provides certified fusion splicing for OSP and ISP telecom applications including long-haul, metro, FTTH, and central office infrastructure.03
Enterprise & Campus Networks
From inter-building backbone links to structured cabling within a campus, iFiber Optix splicing services integrate seamlessly with your existing fiber infrastructure — to your specs, your schedule, and your quality standards.04
Emergency Fiber Restoration
When a fiber cut threatens your operations, speed and reliability are everything. iFiber Optix offers rapid-response mechanical and fusion splicing to restore connectivity fast, with the same quality documentation and testing standards on every project.Splicing Products

Fiber Optic Splicing: Frequently Asked Questions
Fusion splicing uses an electric arc to permanently weld two fiber ends together, achieving very low insertion loss (below 0.05 dB) and is the preferred method for permanent installations. Mechanical splicing uses a precision alignment sleeve and index-matching gel to join fibers without heat, which is faster to deploy in the field but typically carries slightly higher splice loss (below 0.5 dB). iFiber Optix offers both methods depending on your application and timeline requirements.
Our certified technicians can splice all common fiber types including OS1 and OS2 singlemode, and OM1, OM2, OM3, and OM4 multimode fiber. We work with loose tube, tight buffered, ribbon, armored, and aerial cable constructions across both inside plant and outside plant environments.
Every splice performed by iFiber Optix is tested using an Optical Time Domain Reflectometer (OTDR). OTDR traces are provided to the customer as part of a complete splice loss report, documenting the measured loss at every splice point across the fiber link. We do not hand off a job until every result is within spec.
A splice-on connector (SOC) combines a fusion splice and a connector in one unit — you fusion-splice the connector body directly onto the field fiber. A pigtail is a factory-terminated fiber with a connector on one end and a bare tail on the other that you splice onto the plant fiber separately. SOCs deliver splice-quality loss with no epoxy and no polishing required.
