So you can check out the other reviews Crеаtіvе Prоduсt Primeda-tronic 8 Ports RJ11 Telephone and 10/100Mbps Ethernet Over Fiber Converters Extenders - PCM Voice Over Fiber Optic,Universal Single Mode 20Km and Multimode 500m at Amazon.com
only with $198.00
- Universal for Both Fiber Types: Same media converters can supports Single-mode fiber for a long distance up to 20 km(12miles) and Multimode fiber for a distance up to 500m(0.31miles), wavelength 1310/1550 nm
- Extend your Phones and Network: 8 Independent telephone lines + 1 Fast Ethernet (10/100 Mbit/s) port over same Single mode or Multimode fiber cable
- Simple to Install,Plug and Play,No setup or configuration needed, SC connector for fiber optical port, RJ-11 connector for telephone ports and RJ-45 for Ethernet
- No Delay Transmission and Protocol Support: Unlike VoIP products - these converters transmit signals directly over fiber cables, thus offering NO DELAYS, plus support for fax & legacy applications that is not supported by VoIP lines
