Single Mode Steel Tube 1550NM Wideband Couplers
Basic Information:
Wideband CouplersThe dual window Wideband Couplers (WBC) split or couple optical power in two wave-length regions while maintaining a very broad operating bandwidth.
Split and coupling ratios are available from 1% to 99%. WBCs are widely considered one of the most cost-effective solutions for optical power management. The WBC is an all-fiber device, based on Geehe's fused biconic technology, and is designed and manufactured to meet military and Telcordia requirements.
From Taper equipment to software, every step is R&D by own team, quality is more stable.

WDM Cable Types:
1. Single-mode fibers allow one mode to propagate.
2. Multimode fibers support the propagation of multiple modes.
3. Wavelength range is the range of wavelengths the WDM will operate in.
4. Bandwidth, also called channel spacing, is the size of the windows in nm.
5. Channel spacing is the center-to-center difference in frequency between neighboring channels. Two hundred GHz corresponds to .4 nm spacing, 100 GHz corresponds to .2 nm spacing, and 50 GHz corresponds to .1 nm spacing.
6. Number of channels is the number of channels the device has to send information. This number can range from 4 to 160 with design enhancements adding more channels.
7. Insertion loss is the attenuation caused by the insertion of wavelength division multiplexers (WDM) in an optical transmission system.
Polarization-dependent loss is the maximum deviation in insertion loss across all input polarization states.
