The ComNet CNFE2MC Ethernet 2 port media converter and CNFE22MC dual 2 port are designed to transmit and receive 10/100 Mbps data over optical fiber through user selectable SFP options. These models require the ordering of sold-separately interchangeable SFP modules for fiber type, distance and connectors. The CNFE2MC transmits and receives a single channel of Ethernet data and the CNFE22MC transmits and receives two independent channels in one unit. The electrical interface will Auto- Negotiate to a 10 Mbps, or 100 Mbps Ethernet rate without any adjustments. The optical interface operates at a 100 Mbps Ethernet rate. Both are environmentally hardened to operate in extreme temperatures. LED indicators are provided for confirming equipment operating status. Packaged in the exclusive ComNet ComFit housing, the CNFE2MC and CNFE22MC units may be either wall or rack-mounted, or may be DIN-rail mounted by the addition of ComNet model DINBKT1 adaptor plate.

The ComNet™ CNFE2MCPOE Ethernet media converter is designed to transmit and receive 10/100 Mbps data over optical fiber through user selectable SFP modules. These models require the ordering of sold-separately interchangeable SFP modules for fiber type, distance and connectors. The CNFE2MCPOE transmits and receives a single channel of Ethernet data. It also supports IEEE 802.3at Class 1 - 4 as Power Sourcing Equipment (PSE) with up to 30 Watts @ 48VDC. The electrical interface will Auto-Negotiate to a 10 Mbps, or 100 Mbps Ethernet rate without any adjustments. The optical interface operates at a 100 Mbps Ethernet rate. It is environmentally hardened to operate in extreme conditions. LED indicators are provided for confirming equipment operating status.

The ComNet CNFE3DOE2/M allows any combination of two RS-232, RS-422, or 2 or 4-wire RS-485 serial data circuits to be inserted onto any 10/100 Mbps Ethernet-based network. The CNFE3DOE2/M units include two serial data input/output ports, and three Ethernet ports featuring two electrical ports and one SFP port. It may be used to tunnel serial data over an IP network or as a media converter, for converting copper transmission media to fiber. Access one serial device from the Internet and another serial device from a local area network (LAN) using SSH or SSL. The CNFE3DOE2/M provides control of the remote hardware, as if it were connected directly to the PC COM port. A USB to serial converter may be required in new PCs without a DB9 serial connection.

The ComNet CNFE3FX1TX2C/M series is an industrially hardened three-port intelligent switch with light management functionality and an integrated contact closure server. The 100BASE-FX port supports conventional CAT-5e/CAT-6 copper or optical transmission media by selection of the appropriate ComNet SFP* module. A summary fault alarm provides indication via a form c relay in the event of loss of optical link or operating power. The 10/100BASE-TX ports support both auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual MDI/MDI-X switching is not required. The integrated contact closure server is available with 4 or 8 channels and supports individual user selectable wet or dry inputs. Form A relay outputs feature individual user selection of normally open or normally closed operation via the built-in web GUI. The contact server supports 4 modes of operation including one-to-one, one-to-many, many-to-one and stand-alone.

The internal/self-contained 9 to 36 VDC or 24 VAC power supply features redundant power inputs, for the highest possible reliability. The simple to install, CNFE3FX1TX2C/M Series is DIN-rail or panel-mountable, and is ideal for mission-critical applications where very high levels of reliability and network availability are of the utmost importance.

Features

• Full 10/100 Mbps Bandwidth
• Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances of up to 120 km
• Extended ambient operating temperature range of -40° C to +75° C, for use in virtually any environment. Optional conformal coating for humidity with condensation or airborne particulate matter conditions
• SNMP v1/v2c for network management
• Supports Link Layer Discovery Protocol (LLDP)
• Redundant power inputs, for extremely high levels of reliability and availability
• No fans or forced-air cooling; cooling via natural convection eliminates unreliable and troublesome fans/moving parts, with no periodic maintenance requirements.
• Status indicating LEDs provide rapid indication of critical operating parameters.
• Summary fault alarm provides a local or remote indication via dry contact closure in the event of loss of optical link or operating power
• Rugged 19-gauge galvanized and powder-coated steel enclosure.
• Integrated contact closure server supports wet/dry inputs and user selectable normally open or normally closed form A relay outputs.
