4 factors that influence how long your fiber network will last

by www.fiber-mart.com When deploying a fiber network, one of the key factors used to calculate ROI is how long it will operate. After all, some copper networks have lasted 140 years in the UK, even if they can’t necessarily meet today’s high-speed broadband needs in their current form.   Optical fiber [ Continue reading…]

Splicing: How to Properly Fuse Together Fiber Optic Cables

by www.fiber-mart.com Fiber optic splicing is the process of joining two or more fibers together. Whether you’re deploying a new fiber optic network or expanding an existing network, you must ensure your fibers are properly spliced to avoid network disruptions.   Splicing fibers is commonly used to rejoin fiber optic cables [ Continue reading…]

Difference between Gigabit optical modules and 10G optical modules

by www.fiber-mart.com It is easy to understand literally that the main difference between Gigabit optical modules and 10 Gigabit optical modules is that the transmission rate is different. The transmission rate of the Gigabit optical module is 1000 Mbps, and the transmission rate of the 10 Gigabit optical module is 10 Gbps. [ Continue reading…]

What is Single fiber CWDM MUX and DEMUX

by www.fiber-mart.com In CWDM networks, bidirectional CWDM MUX DEMUX (also called dual fiber CWDM MUX DEMUX) uses the same wavelengths for transmitting and receiving. It is often used in dual way transmission applications. The working principle is easy to understand. A duplex fiber cable links two dual-fiber CWDM MUX DEMUXs [ Continue reading…]

What is the OADM Multiplexer?

by www.fiber-mart.com The OADM, optical add drop multiplexer, is a gateway into and out of a single mode fiber. In practice, most signals pass through the device, but some would be “dropped” by splitting them from the line. Signals originating at that point can be “added” into the line and [ Continue reading…]

What is the difference of Copper SFP and Optic SFP

by www.fiber-mart.com The Gigabit RJ45 copper SFP transceiver supports 1000Mbps over Cat5 cables with RJ45 connector interface, which operates on standard Cat5 unshielded twisted-pair copper cabling of link lengths up to 100 m (328 ft). For short-distance links on a Gigabit switch, it makes no difference if you use SFP [ Continue reading…]

How to choose the PLC splitter correctly?

by www.fiber-mart.com PLC splitter is a simple passive component which plays an important role in the applications of technologies like GPON, EPON and BPON. It allows a strand of fiber optic signal being equivalently splitted into several strands of optical signal, which can support a single network interface to be shared [ Continue reading…]

What are the Main parameters of the optical transceiver modules?

by www.fiber-mart.com Main parameters of the optical modules 1. Transmission rate The transmission rate refers to the number of bits transmitted per second in units of Mb/s or Gb/s. Main rates: 100M, Gigabit, 2.5G, 4.25G and 10G, 25G, 40G, 56G, 100G, 120G, etc.   Therefore, based on different data rate, [ Continue reading…]

A Guide to Laser Selection for Coherent Optical Fiber Systems

by www.fiber-mart.com A coherent optical transceiver has a transmitter (TX) laser and a local oscillator (LO) laser, which can be based on two separate lasers or a single laser. The laser specification requirements are different for different transmission distances. Here we discuss a few key laser requirements and where they will be [ Continue reading…]

HOW DOES FIBER-OPTIC INTERNET COMPARE WITH THE COMPETITION?

by www.fiber-mart.com Because of the cost of installation and natural resistance to change, many businesses and individuals are hesitant to pursue a Fiber-Optic connection. This decision is perfectly rational when it comes to a home environment: if you are happy with your current connection, then why change? When it comes [ Continue reading…]
