Mechanical splices - questions and answers. Installers who begin their adventure with fiber optics have many questions on splicing optical fibers. In general, the joining methods used for optical fibers are not as simple as in the case of connecting copper cables. To facilitate the understanding of mechanical splicing, we decided to answer the most frequently asked questions.
Fiber Optic Mechanical Splice: ULTIMODE FAST-MS1 [5 pcs.]
Mechanical splice ULTIMODE FAST-MS1
  • What is a mechanical splice? Mechanical splice is a component for joining two separate optical fibers, made ​​with high accuracy allowing for precise and permanent positioning of the prepared fiber ends to minimize signal attenuation. The device also protects the connection from mechanical and environmental damage.
  • What tools are needed to make a mechanical splice? The installer needs fiber optic stripper L5905, precision fiber cleaver L5801, IPA solvent cleaner L5915, and dust-free Kim-Wipes L5913. Other very useful tools are visual fault locator L5934, optical power meter L5821, optical laser source L5825, fiber scraps trash can L5918 and scissors for cutting Kevlar(R) L5904.
  • What fibers can be to joined using mechanical splices? Mechanical splices can be used for joining single-mode and multimode fibers with buffer or jacket diameter of 250 μm and 900 μm.
  • What is the attenuation of mechanical splices? Properly installed mechanical splice has an attenuation of less than 0.15 dB. Practice shows that skilful installers using mechanical splices are able to achieve attenuation level identical with that of fusion splices. The loss of a splice depends on many factors, but mainly on the accuracy of the fiber cutting and the manual skills of the installer.
  • Are mechanical splices strong and durable? Mechanical splices are sufficiently strong and durable. However, they should not be exposed to longitudinal forces, therefore they should always be placed in specially designed compartments in installation boxes or distribution frames. Well-protected mechanical splices guarantee durability of the connections.
Design of a multiswitch system for a multi-family building performed with the latest SatNet 3.0 app. Before installation, multiswitch systems in multi-family buildings have to be properly designed. The initial parameters for the calculations are: network topology, the number and kind of multiswitches, attenuation of the cable used. The design process involves optimal selection of the system components and setup of their parameters so that the output signals in all outlets are compliant with appropriate standards.
The free TERRA SatNet application allows for designing SMATV systems with the calculation of projected levels of terrestrial and satellite signals for each outlet in the network. This allows the designer/installer, sitting in front of the monitor, to predict what devices will be needed for distributing the signals and what settings like gain and cable equalization level (slope) will provide the desired results. In all cases these settings fully correspond with the optimum values in real networks.

An example of a SMATV system with 96 outlets, designed with the use of the latest SatNet 3.0 version of the software. The system for a multifamily building uses a single master antenna set and is based on bus topology with splittersand taps, and Terra MV-524 R70724 multiswitches. All active components of the system are powered from the SA-51 R70501 amplifier.
Which UPS to choose? When choosing an uninterruptible power supply, it is important to take into account the output voltage waveform. Depending on the kind of a UPS, the waveform may be rectangular, simulated (approximated) sine wave, or pure sine wave. The waveform of the output voltage is important for the powered devices .
The waveforms of the output voltage generated by UPSes:
red - pure sine wave, blue - simulated sine wave, violet - square wave
Most devices can be powered by UPSes generating simulated sine wave like CyberPower DX850E N9720. Some devices (especially consuming higher power) are equipped with active PFC circuits which aim to improve the power factor. Such devices require the use of UPSes with pure sine wave, such as the CyberPower CP900EPFCLCD N9724.
An important feature of UPSes is AVR (Automatic Voltage Regulation). Its job is to lower (trim) or increase (boost) the AC line voltage. When, for example, the line voltage is too low, a UPS with AVR does not switches to battery mode, but it increases the output voltage to the rated value (in Europe to 230 VAC).
BNC video output in Sunell cameras. Each time, the installer of a CCTV camera has to set the focal length and sharpness. It cannot be done in advance but only in the selected location, and becomes a problem when the camera is mounted at a great height. The installer climbing on a ladder with a laptop can end up falling down or dropping the laptop, not to mention the difficulties in working under these conditions.
