The IMC-101G-T from Moxa is an industrial media converter for converting Ethernet signals between copper and fiber optic cables. It enables connection of 10/100/1000BaseT(X) via RJ45 interface with 1000BaseSX/LX/LHX/ZX through an integrated SFP slot. The devices are designed for use in demanding industrial environments where high reliability, availability, and flexibility are required.

Applications
The IMC-101G-T is suitable for applications in automation technology, power supply, and marine environments. It enables integration of network components across different transmission media, thereby improving the range and stability of industrial networks. Certification for hazardous areas (Class 1 Div. 2, ATEX Zone 2, IECEx) also makes it suitable for locations with increased safety requirements.

Functions and Features in Detail
The converter features an SFP slot, compatible with more than 20 SFP modules from Moxa’s SFP-1G series. This allows adaptation to various fiber optic standards such as SX, LX, LHX, or ZX. The RJ45 interface supports Auto-MDI/MDI-X and Auto-Negotiation, enabling connection without manual configuration. An integrated relay output allows reporting of power failures and port status changes, which is important for monitoring and fault diagnosis in critical systems.

Technology Explained Simply
The Link Fault Pass-Through (LFPT) mechanism ensures that in case of fiber optic link failure, the affected port is marked as unreachable in the network, improving network availability. Redundant power inputs via a terminal block enhance operational safety, as a failure of one power source can be compensated by a second. Power supply is via 12 to 48 VDC, with maximum current consumption of 200 mA. An integrated overcurrent protection safeguards the device against damage from current surges.

Compatibility and Accessories
The SFP slot is compatible with modules from Moxa’s SFP-1G series, supporting various fiber optic standards such as SX (for short distances), LX (for medium distances), LHX (for longer distances), and ZX (for very long distances). Using these modules extends the range and flexibility of the converter.

Mounting and Installation
The device is mounted on a DIN rail, enabling simple and standardized installation in enclosures. The metal housing provides mechanical stability and protection against external influences. The protection rating IP30 protects against contact with objects larger than 2.5 mm and against splashing water, but not against direct water jets or precipitation. Mounting requires no special tools, as fixation is done via the DIN rail.

Operational Advantages
The IMC-101G-T is characterized by high operational reliability, supported by redundant power supply, LFPT, and alarm functions. The extended operating temperature range of -40 to 75 °C (for -T models) enables use in extreme environments. Certifications according to EN 55032/35, FCC Part 15B, CISPR 32, and IEC 61000-4-2/-3/-4/-5/-6/-8/-11 ensure EMC and EMS compliance. The MTBF of 500,540 hours (according to Telcordia standard) demonstrates the high lifespan and reliability of the device. The 5-year manufacturer’s warranty underscores the product’s quality.

Scope of Delivery
The scope of delivery includes the IMC-101G-T media converter, a quick start guide, and a warranty card.
