Dual Fiber DWDM MUX 4 Channel Fiber Optical Passive Optical Multiplexer LC UPC
During the 1980s, fiber optic data communications modems used low-cost LEDs to put near-infrared pulses onto low-cost fiber. As the need for information increased, so did the need for bandwidth. Early SONET systems used 1310 nanometer lasers to deliver 155 Mb/s data streams over very long distances.
But this capacity was quickly exhausted. Advances in optoelectronic components allowed the design of systems that simultaneously transmitted multiple wavelengths of light over a single fiber. Multiple high-bit rate data streams of 2.5 Gb/s, 10 Gb/s and, more recently, 40 Gb/s, 100 Gb/s, and 200 Gb/s could be multiplexed through divisions of several wavelengths. Thus, WDM was born.
There are two types of WDM today:
DWDM is designed for long-haul transmission, with wavelengths packed tightly together. Vendors have found various techniques for cramming 40, 88, 96, or 120 wavelengths of fixed spacing into a fiber. When boosted by Erbium Doped-Fiber Amplifiers (EDFAs)—a performance enhancer for high-speed communications—these systems can work over thousands of kilometers. For robust operation of a system with densely packed channels, high-precision filters are required to peel away a specific wavelength without interfering with neighboring wavelengths. DWDM systems must also use precision lasers that operate at a constant temperature to keep channels on target.
Sharetop’s 6500 Packet-Optical Platform converges packet, Optical Transport Networks (OTNs), and flexible WaveLogic Photonics in a single platform to streamline operations and optimize footprint, power, and capacity. Built for efficient network scaling from the access to the backbone core, it offers the full gamut of CWDM and DWDM solutions, with DWDM solutions ranging from 10 Gb/s to beyond 200 Gb/s.
