Wavelength Division Multiplexing (WDM) is a technology used in fiber-optic communication to transmit multiple signals over a single fiber. WDM divides the fiber into channels with different wavelengths, allowing multiple signals to be transmitted simultaneously. There are three main types of WDM: WDM, CWDM, and DWDM, all of which increase the capacity of the fiber.
There are two main types of fiber for telecommunications: multimode and single mode. What are the differences between these, and when should you use single mode or multimode?
FPD66 is a compact wall box for DIN rail and wall mounting of fiber optic cables. Despite the modest dimensions of the box, the fiberoptic bending radius and the installers ability to do work in the box, is taken care of. To ensure easy assembly, the adapter plate and the lid can be removed.
Wavelength Division Multiplexing (WDM) is a cost-effective and efficient method for increasing the capacity of existing fiber lines. This is achieved by dividing the fiber into channels with different wavelengths, allowing multiple signals to be transmitted over the same fiber. Each wavelength carries its own signal with full bandwidth. When needed, the systems can be expanded to gradually increase the transmission capacity of the line.
Digitalization is relevant in industrial environments. Equipment and processes can be remotely controlled and monitored. This places great demands on the communication equipment. Fiber optic cables are immune to electromagnetic noise and have high transmission capacity. This makes fiber optics the natural solution for modern and robust communication.
Wavelength multiplexing is a good and affordable method of transmitting multiple signals across the same fiber. Each wavelength (color) transports a signal. In this way, you can significantly increase the capacity of existing fiber lines. Combined with Optical Add / Drop Multiplexer (OADM), one can pick and / or add single wavelengths on the way between endpoints. A major advantage of using passive wavelength multiplexing is also that the method is protocol and speed independent.
Since the beginning of 2017, Mesta, Norway's largest contractor in the field of maintenance and road engineering, have worked on a major upgrade with the security system in a tunnel in Bergen, Norway. To avoid closing the tunnel during the day, all work has been done by night. Because of this, it has been important to have a robust and flexible temporary safety system inside the tunnel.
In relatively few years, high speed internet access has become a necessity for most people in daily routines. No matter if you are working from home, watching Netflix from the couch, listening to music from Spotify or gaming online, a stabile and fast connection is needed. For years, WDM technology has been applied in order to achieve this infrastructure, at a reasonable cost and within the physical limitations that we face.
The ever increasing demand for data bandwidth has led to a massive roll-out of optical fibres in both central and rural areas of Norway. The passive infrastructure has been deployed, awaiting future technology upgrades. Point to point or point to multipoint networks, Single Family Units or Multi Dwelling Units, we have created a set of product solutions that will secure traffic stability and subscriber satisfaction. The solutions comprise ODF solutions in the ONT, outside splice closures with or without integrated optical splitters, a selection of wall boxes and products for inside optical wiring down to the OLT at the subscriber´s residence.

Foss as a long-term supplier of Splice-on connectors for Slovak Telekom, provides training and special holders for fiber optic splicers.
An optical connector is usually male. Two connectors are connected together via an adapter and characterized by two optical parameters, insertion loss and reflected power. Additionally, the connectors must meet geometrical requirements for the ferrule (radius of curvature, apex offset, and protrusion/retraction).
The MDC connector from US CONEC belongs to the class of VSFF (Very Small Form Factor) duplex connectors for singlemode and multimode applications. The MDC connector uses a standard 1.25mm diameter ferrule, also used for LC connectors and is terminated onto 2-fibers optical cable with outer diameter up to 2 mm.
