HMC-652E is a 10/100 RJ45 to 100FX Converter Copper to the Fiber media converter. It's an inexpensive and minimal solution with automatic MDI/MDI-X and Auto-negotiation, NWay support on RJ-45. The device uses LED signaling to inform users of its transmission activity. The converter is completely transparent when connected, meaning that network performance remains unchanged. The device is available in single- and multi-mode fiber with data transmission delivery at distances of 2/30km depending on request. For added flexibility, this media converter is available with SC/ST, and SFP slot for SFP module. This media converter operates between temperatures of -10℃~60℃ (14°F~140°F). The device has a standard size to fit on an in-rack solution with multiple media converters.


Rugged and Robust Design
Responding to the issues of consistent operation in harsh industrial and mission-critical environments, the HMC-652E is built in a rugged and durable housing. Enclosed in IP30-grade casing, the media converter provides superior protection from severe temperatures extending from -10°C to 60°C. Capable of DIN-Rail mounting, the device is simple to install easy to fit in industrial environments that have limited spaces. The HMC-652E also features DC jack with locking function to ensure continuous power connectivity in mission-critical applications where vibration plays a key role and extremely tight connections are crucial.

Economic and Space-saving Design
Responding to the issues of design in mission-critical environments, the HMC-652E is designed in a space-saving, compact and slim housing. This standalone low-cost media converter provides transparent conversion at 100Mbps without data stream interference and inexpensively connects both 10/100Mbps copper port and 100Mbps fiber port in a small enclosure. The compact size allows the converters to be wall-mounted to save space. The HMC-652E is extremely simple to install and operate, and thus saves your valuable time and money. 

Fault-tolerant and User-friendly Monitoring
Network administrators can now easily monitor and troubleshoot issues associated with device functionality and link activity using the HMC-652E advanced features. LFS (Link Fault Signalling) feature on the device provides critical information about link status and enables you to easily detect optical signal strengths and faulty links on both copper and fiber ports, and significantly minimizes outage. And the LEDs on the HMC-652E convey essential diagnostic and status information of device power, link activity on ports etc. and allow you to easily monitor without having to get into tight spaces.

Easy Plug-and-play Operation
Being a compact, lightweight media converter, the HMC-652E is an easy-to-setup and ready-to-use solution for dispersed or emerging networks. Featuring Auto-MDI/MDIX and Auto-negotiation, the media converter automatically detects and configures the best mode of operation over a link. This eliminates the need of user setup or configuration procedure and simplifies installation. And once installed the media converter operates automatically. In addition, the Link Fault Signaling DIP switch on the HMC-652E provides a simplest and quickest way to enable or disable LFS (Link Fault Signaling) function on the device.

Local loopback and Remote loopback
Selecting Loopback mode on the interface allows administrators to remotely isolate and localize network problems. Local loopback is provided on the closet segment and Remote loopback is provided on the secondary segment. Administrators can send test packets to a link and inspect the returned packets to diagnose each link of the network.
