System Design
Fiber Optic Telephone Transmitter & Receiver
HD-S1/2/4/6/8/16/30P-T/RF series can transmission 1-Channel/
2-Channel / 4-Channel/6-Channel/8-Channel/16-Channe/30-Channel voice over 1 single
core fiber.
Stand-alone or rack-mounted optional.
The HD-S1/2/4/6/8/16/30P-T/RF cards (W/O metal case )
can be inserted into our 18-slots, 19inch 4U
rack-mountable chassis with redundant power
Single-Mode or Multi-Mode
HD-S1/2/4/6/8/16/30P-T/RF units are designed to support FC /PC Optical connector ( SC/PC or ST/PC optical connector is available for custom-made).
The Transmission distance Range according to the Optical Budget.
Manufacturer's default standard is single mode 20Km .
Remark
•The Optical Power Budget fit Multi-mode(62.5/125m),Single-Mode(9/125 m).
•When using 50/125 m multimode fiber, subtract 3 dB from the optical power budget.
•Optical transmission distance is limited to optical loss of the fiber and any additional loss introduced by connectors, splices and patch panels.
•Maximum transmission distance is also limited by fiber bandwidth.
•Power adapter for stand-alone units is manufactured by third party .Power adapter included US, European, UK or Australian power plug.
•Please feel free to contact factory for any special requirement and customization
