VBS-22 Evanescence-Based Variable Split Ratio Fiber Splitter/Coupler

Single Mode WDMs; 980 to 1625 nm; Operating Bandwidth ±5 to ±20 dB; Insertion Loss ≤0.15 to ≤0.6 dB; Isolation ≥13 to ≥32 dB; Fiber Type HI1060flex, OFS, BF05635-02, SMF-28e LightComm Technology’s 980/1550 nm and 1480/1550 nm single mode wavelength division multiplexers (WDMs) are widely used in EDFA which can combine the pump power and optical signal into the Er-fiber. 1310/1550 nm single mode WDMs can be used to combine or split 1310 nm and 1550 nm optical signals which double the fiber transmission capability and ensure bi-directional communication in a single fiber.LightComm technology also provides different special wavelength WDMs such as 980/1064 nm, 1064/1550 nm or 1550/1625 nm WDM. Raman Pump Combiners are designed for combining multiple pumps with different wavelengths for Raman amplifiers.In addition to standard size WDMs, LightComm Technology also provides mini size single mode WDMs featuring the same function and performance as the regular WDM couplers. These mini size WDMs are widely used in EDFA modules and communication systems. Key Features: Single Mode Regular and Mini Size Versions Available High Isolation Low PDL Low Excess Loss High Stability and Reliability Applications: EDFA Modules; WDM Systems; Testing Instruments

Multi Mode WDMS, Pigtail, Miniature and Freespace to Fiber Style; 400 to 1600 nm; Return Loss 40, 50, 60 dB; Insertion Loss 0.8, 1.0, 1.2 dB; Power Handling 200, 500 mW OZ Optics’ WDM series of multi mode wavelength division multiplexers (WDMs) are used to combine light of different wavelengths into a single fiber. The light from each fiber is first collimated. The collimated beams are then combined using a dichroic filter, with typically the longer wavelength transmitted from port T, the shorter wavelength reflected from port R. The combined beams are then focused into the output fiber at Port 1. OZ Optics manufacturers wave division multiplexers for both telecom and non-telecom applications. One advantage of OZ Optics’ WDMs is that different fiber types can be used on the input and output ends of the device. This is especially useful in fiber amplifier applications, when the Erbium doped fibers have a different core diameter and numerical aperture. WDMs with 1 dB typical insertion loss have been made this way. OZ Optics also offers source to fiber wavelength division multiplexers, where the sources are mounted directly onto the device. Miniature size WDMs are ideal for telecommunication applications such as drop/add filters for either coarse WDM (CWDM) or dense WDM (DWDM) applications. They are also used for combining 980 to 1080 nm pump light with 1550 nm signals in erbium doped fiber amplifiers (EDFAs). Variants with higher extinction ratios are available on request. OZ Optics specializes in manufacturing custom designed WDM's. Contact AMS Technologies for further information.
