Fiber optic cable

What is fiber optic cable

Fiber optic cable consists of one or more optical fibers enclosed in a protective sheath. Data is transmitted over the fiber as light pulses, which provides enormous bandwidth and almost no attenuation over long distances.

In simple terms, optics is like a water pipe for light: a beam runs along a thin strand, carrying information farther and faster than copper wire. Copper is limited by distance and interference; fiber — practically not.

Single-mode and multi-mode

Single-mode fiber (OS2, SMF) carries one beam of light and is designed for long links — from 2 km to 120 km. Multi-mode (OM1-OM5, MMF) carries several beams at once, is cheaper in terms of active equipment, but is limited in distance (up to 550 m for OM4/OM5) — ideal for data centers and buildings.

How to choose fiber optic cable

For backbones between sites take single-mode OS2. For a structured cabling system inside a building — multi-mode OM4 or OM5 (for 40G/100G). Consider the number of fibers (usually 2, 4, 8 or 12), the outer sheath type (armored for outdoor routing) and the connectors (LC, SC, MPO).

Where "Fiber optic cable" is used

Fiber optic cable is in demand when building and operating network and engineering infrastructure: in data centers, communication nodes, workplaces, at critical information infrastructure (CII) facilities, in banks and state corporations, as well as in the circuits of the Ministry of Internal Affairs, the FSB and other law enforcement agencies.

What to consider when choosing

When preparing a technical specification, rely on the workload profile, required interfaces and standards, operating conditions and information security requirements, including CII protection and the use of cryptographic information protection tools. Fintech JSC helps to form correct requirements and select a solution.

Supply and KTRU codes

Within state and corporate procurement, fiber optic cable is supplied under Federal Law 44-FZ and 223-FZ. Items are selected by KTRU codes:

• 43291900000 — Optical fiber cables (including OPGW, self-supporting and dielectric cables)
• 43291910000 — Communication cables (power and control cables for assembly)

Fintech JSC provides certificates of conformity, cable product passports and test protocols per GOST R 56938.

Detailed description and purpose

Fiber optic cable is a profile solution for equipping and developing a company's infrastructure. Depending on the task, it acts as an element of the network, a computing circuit or an engineering system, and ensures stable operation of services where continuity, data protection and regulatory compliance matter. Fintech JSC selects a fiber optic cable configuration for the customer's specific technical specification rather than "one size fits all", so the result is a working solution rather than just a box.

Technical characteristics worth paying attention to

When forming requirements for fiber optic cable, focus on the workload profile, operating conditions and industry constraints. There are no universal "best" parameters — what matters is how well they fit your infrastructure.

• Standards and protocols. Clarify the supported standards and exchange protocols — they determine compatibility with the equipment already deployed.
• Interfaces and performance. Check the set of ports and interfaces and build in a performance margin for 2–3 years of growth.
• Operating conditions. For data centers, communication nodes and industrial sites, temperature range, dust and moisture protection and power redundancy are critical.
• Information security. For CII and government sites, information security tools, FSTEC/FSB certificates and import-substitution requirements must be considered.
• Manageability and monitoring. Centralized management and logging capabilities simplify operation and audit.

Typical use cases

Fiber optic cable is in demand in various environments: in banks and state corporations, at critical information infrastructure (CII) facilities, in data centers and communication nodes, at employees' workplaces, and in departmental networks (Ministry of Internal Affairs, FSB and other law enforcement agencies). Each scenario has its own level of protection and redundancy.

Supply and project implementation stages

1. Audit and TOR. We study the current infrastructure, regulatory requirements and budget; we form a correct technical specification.
2. Selection and design. We propose a fiber optic cable configuration compatible with your environment.
3. Approval under 44-FZ / 223-FZ. We prepare documentation, a technical and commercial proposal and a budget estimate.
4. Supply. We assemble equipment with passports, certificates and protocols.
5. Installation and commissioning. Fintech JSC engineers perform installation, configuration and integration into the existing environment.
6. Training and acceptance. We train the customer's staff, hand over documentation and put the facility into operation.
7. Support. Warranty and service support, consultations on infrastructure development.

Requirements for the customer's infrastructure

Before starting the supply it is useful to prepare: a diagram of the current network or circuit, a list of compatible equipment, information security requirements (if any), and a placement and power supply plan. The more accurate the input data, the faster and more predictable the project.

Documents, certificates and regulatory compliance

Fintech JSC supplies fiber optic cable with a full package: passports, certificates (including FSTEC and FSB where applicable), protocols and warranty obligations. We take into account the requirements of 44-FZ and 223-FZ, import substitution and CII protection. Where needed, we select certified information security tools.

Common errors when choosing

Typical mistakes: choosing "by minimum price" without considering compatibility, ignoring information security requirements for CII, lack of performance margin and refusal of service support. They lead to rework, downtime and risks — we help to avoid them already at the TOR stage.
