Newtown, CT 06470
Jun 19, 2002 Series AT/AR7400 20-bit, four-channel, digital multiplexer allows two stereo or four monaural audio signals to be digitally encoded and transmitted on one optical fiber. Quality of signal is maintained under all optical conditions through maximum optical path loss of 20 dB. Medium-haul performance has 80 dB signal to noise ratio and operating temperature range of -40 to +74°C. |

Merrimack, NH 03054
May 17, 2002 Bi-directional Wavelength Division Multiplexer (BWDM) uses 2 separate wavelengths to carry 2 distinct channels up to 20 km distance. Either 1310 or 1550 nm wavelength is used to transmit, while other wavelength is used to receive, eliminating need to install second fiber and doubling capacity of existing cable. It is suitable for MAN and LAN applications. |
