Types of Fiber Optic Cable Tests

Visual Inspection: The primary purpose of visual inspection is to identify visible defects or damages on the fiber optic cable and connectors. This initial step involves using fiber optic inspection microscopes and videoscopes to examine the fiber ends and connectors for cleanliness, scratches, cracks, or other physical damages.

If any contaminants or physical damage are detected, the connectors should be cleaned using appropriate fiber optic cleaning tools. Visual inspection is a crucial first step before conducting any other tests, as it ensures that the connectors are in good condition.

Optical Loss Test Set (OLTS) Testing: The purpose of OLTS testing is to measure the total insertion loss and optical return loss (ORL) of the fiber optic link. This test uses a light source and a power meter. The light source transmits a known power level through the fiber, and the power meter measures the received power level.

By comparing the transmitted and received power levels, the insertion loss can be calculated. Additionally, the ORL test measures the amount of light reflected to the source. OLTS testing is crucial for determining the efficiency of the fiber optic link.

Optical Time Domain Reflectometer (OTDR) Testing: OTDR testing is used to measure the length, attenuation, and reflectance of the fiber optic link, as well as to locate faults.

An OTDR device sends light pulses down the fiber and measures the light that is reflected back. The resulting trace or graphical representation shows the fiber’s length, attenuation, and any faults or splices along the link. This test is essential for identifying the exact location of issues such as breaks, bends, or splices within the fiber optic link.

End-Face Inspection: Ensuring the cleanliness and condition of fiber optic connector end-faces is vital for optimal performance. End-face inspection involves using a fiber optic inspection microscope to examine the connector end-faces for contaminants, scratches, or any physical damages.

If any issues are detected, the end-faces should be cleaned and polished using appropriate cleaning tools and techniques. Clean and undamaged end-faces are critical for maintaining high-quality connections and reducing signal loss.

Polarization Mode Dispersion (PMD) Testing: PMD testing measures the dispersion characteristics of the fiber optic link, which can affect high-speed data transmission. Dispersion can cause the different polarization modes of light to travel at different speeds, leading to signal distortion and degradation, especially in high-speed networks.

PMD analyzers are used to measure these dispersion properties, ensuring they are within acceptable limits for the network’s intended data rates. This test is particularly important for long-distance and high-bandwidth applications, where even small amounts of dispersion can significantly impact performance.

The Application of 100BASE-X SFPs Transceiver

In PC organizing, Fast Ethernet is an aggregate term for various Ethernet norms that convey traffic at the ostensible pace of 100 Mbit/s (the first Ethernet speed was 10 Mbit/s). Quick Ethernet is now and again alluded to as 100BASE-X, where "X" is a placeholder for the FX and TX variations. The standard indicates the utilization of CSMA/CD for media get to control. A full-duplex mode is additionally determined and practically speaking every single current system uses Ethernet switches and works in full-duplex mode.

The "100" in the media type assignment alludes to the transmission speed of 100 Mbit/s, while the "BASE" alludes to baseband flagging. The letter following the scramble ("T" or "F") alludes to the physical medium that conveys the sign (turned pair or fiber, separately), while the last character ("X") alludes to the pre-owned encoding technique.

Little Form-factor Pluggable (SFP)

The little structure factor pluggable (SFP) is a reduced, hot-pluggable handset utilized for both media transmission and information interchanges applications. The structure factor and electrical interface are determined by a multi-source understanding (MSA) under the protection of the SFF Committee. It is a mainstream industry design mutually created and bolstered by many system part sellers. The SFP interfaces a system gadget (a switch, switch, media converter, or comparable gadget) to a fiber optic or copper organizing link.

100BASE-TX SFP Transceiver

100BASE-TX is the prevalent type of Fast Ethernet and runs more than two wire-sets inside a class 5 or above link. Like 10BASE-T, the dynamic sets in a standard association are ended on pins 1, 2, 3, and 6. Since a run of the mill class 5 wound pair link contains 4 sets, it can bolster two 100BASE-TX joins with a wiring connector. Each system portion can have the greatest cabling separation of 100 meters (328 ft). In its run of the mill design, 100BASE-TX utilizes one set of bent wires toward every path, giving 100 Mbit/s of throughput toward every path (full-duplex). BlueOptics© SFP 1000BASE-T, 100M, Copper Transceiver is one choice for this classification with RJ45 connector from CBO is intended for Gigabit Ethernet (GbE) rapid utilizations of up to 1.25 gigabits every second over Cat5 Twisted Pair Cable.

100BASE-FX SFP Transceiver

100BASE-FX is a rendition of Fast Ethernet over optical fiber. This application utilizes a 1310nm close infrared (NIR) light frequency transmitted using two strands of optical fiber, one forgets (RX) and the other for transmitting (TX). The greatest length is 412 meters. The BlueOptics© BO05A13602 SFP handset with LC duplex connector from CBO is intended for short-go multi-mode Fast Ethernet (FE), Fiber Channel over Ethernet (FCoE), or OC-3/STM1 SDH/SONET utilizations of up to 155 megabits for every second.

How to Choose Fiber Optic Attenuators

The need for Fiber Optic Attenuators-

In fiber-optic technology, beginners are often confused with why it is necessary to use optic attenuators to reduce light intensity. To increase the signal power level we generally use amplifiers?

The truth behind it is too much light can overload a fiber optic receiver and fiber adapter. When a transmitter delivers too much light optical fiber attenuators are required, such as when a transmitter is very close to the receiver.

Working of a Fiber Attenuator –

By absorbing light such as a neutral density thin-film filter attenuator usually works and even it works by scattering the light such as an air gap. They should not reflect the light as it may cause unwanted back reflection in the fiber system.

There is another type of attenuator that utilizes a length of high-loss optical fiber and it operates upon its input optical signal power level in such a way that its output signal power level is less than the input level.

Reduction in power is done by means such as diffusion, absorption, scattering, scattering, dispersion, deflection, and diffraction, etc. You can buy an optical circulator online.

Important Feature a Fiber Attenuator Should Have-

For an attenuator, the most important spec is its attenuation versus wavelength curve. On all wavelengths used in the fiber system or at least on all flat attenuators should have the same effect.

Types of Attenuators-

Generally, there are two functional types of fiber attenuators: plug style (including bulkhead) and in-line.

A plug style the attenuator is employed as a male-female connector where attenuation takes place inside the device i.e. on the light path from one ferrule to another. These include SC attenuator, FC fiber optic attenuator, LC attenuator, ST attenuator, and more.

By splicing its two pigtails, an in-line attenuator is connected to a transmission fiber.

As these attenuators use various phenomena to decrease the power of the propagating light, the principle of operation of optical attenuator becomes different.

There is also the availability of Variable fiber optic attenuators, but they usually are precision instruments used in making measurements.
