Gigabit 1 optical 2 electrical VLAN isolated optical fiber transceiver

This device can provide 2 independent and completely isolated wire-speed 1000M Ethernet channels in one optical direction (single fiber or dual fiber). It is very suitable for building an intranet and a public information network at the same time, and requires a high degree of isolation between the two networks It is also particularly suitable for occasions where fiber optic cable resources are particularly tight and many independent Ethernet channels are required. It is also very suitable for expanding the bandwidth of DSLAM without changing the original optical path.
 
This super optical fiber transceiver not only saves one device, but also saves 3 pairs of optical fibers.
 
  • Integrated circuits based on independent intellectual property rights
  • Provide link aggregation channels for network switches, with a bidirectional bandwidth of 800M
  • Channel isolation to ensure complete physical isolation of the two groups of network services transmitted through the same optical fiber line
  • Can provide 2 route speed 1000M Ethernet channel
  • The Ethernet port supports AUTO-MDIX (crossover and direct connection self-adaption);
  • The local device can indicate the remote 220V power down state
  • Ethernet electrical port supports auto-negotiation of speed and duplex mode, parallel/crossover line adaptive function; or forced mode
  • Support ultra-long frame transmission, fully compatible forwarding of various extended protocol data frames
  • 4*1000M Ethernet channel, completely physically isolated. Two groups of network services transmitted by the same optical fiber line
  • Support light path interruption transfer function, which can transmit interruption alarm to the peer device
  • Provide multiple optical interface configurations such as dual/single fiber transmission, different wavelengths and luminous power
  • Abundant working status indicators, which can easily and accurately understand the working status of equipment interfaces and links
  • Rack-mounted equipment network management interface adopts SNMP

Equipment typical application legend one
 
When the device is set to logical isolation, mutual independent communication between A-A1, B-B1, C-C1, D-D1 can be realized.
 
Our 4 channels are completely physically isolated, which is more secure than VLAN isolation. VLAN is isolated in the uplink channel. The packets of the two channels are still crossed together for statistical multiplexing, while we are time division independent channels, proprietary optical coding, and protocols.
 
In the government, military, etc., where the internal network and the external network need to be networked separately, and the security requirements are high, the use of super optical fiber transceiver is a better solution.
