MTRJ Visual Fault Locator in Fiber industry:
This VFL tester is ideal for both singlemode and multimode MTRJ patchcord/cable plant inspection. Breaks, bad splices, tight crimps, faulty splice and bad connection can be identified by means of visible red laser emitting from VFL.
The MTRJ Universal Visual Fault Locator incorporates a male MTRJ receptacle with guide pin*1. Laser (650nm) is employed as the MTRJ receptacle output, which provides visibility of up to 5km. The laser is driven by an automatic power control circuit, which eliminates the degradation of the output power due to aging as well as temperature effect. Each of the two optical fibers in the MTRJ receptacle can be turned on/off individually. It features a choice of continuous wave (CW) and modulated(1Hz) operations, which provides usersan alternate way to identify faults in theindividual fiber.

WDM Technology
Below are some of the WDM technology for reading. Welcome for any comment or visit our site at www.megbold.ca
Wavelength-Division Multiplexing
WDM avoids many of the constraints and implementation difficulties that limit the performance of Time-Division Multiplexing (TDM) systems. Rather than increasing the data rate to handle more information like a TDM system, a WDM system simply carries several optical signals, each at its own wavelength and each respecting the data-rate limitations applicable to the transmission system.
This technique can increase the capacity of existing networks without the need for expensive re-cabling and, thus, can significantly reduce the cost of upgrading a network. It also opens up a new era of marketing flexibility: the transport infrastructure can provide not only cable and fiber for rent, but also individual wavelengths. One wavelength could be used for cable TV, another for telephony, another for internet traffic, another for video-on-demand, four others reserved to a specific customer, eight others rented to five different cstomer, and so on.
