What if your industrial environment enclosures are so small, that you are searching for the smallest possible, Media Converter with DIN rail mount, yet, with powerful Gigabit Ethernet configurable to a Fast Ethernet Fiber port? AN-UMG130-AS-20-mini-I & AN-UMG150-AS-20-mini-I Single Mode Single Fiber WDM Media Converter set does just that! It’s one of the smallest in the industry – dimensions only 60* 50* 35 mm (L*W*H) – yet, it still offers DIN rail mount, external power support DC 9 – 55V and WDM single fiber WDM 20 km (A side 1310/550mm & 1550/1310nm B side. The fiber port is not only fixed gigabit 1000FX as it is for most similar devices – you can manually set the speed to 100FX to work with 100FX devices in pairs as well. With functions such as broadcast storm protection, balanced traffic, isolation conflict, error detection, and crash reset, it is suitable for high-flow data applications such as video transmission. Super lightning protection function: lightning protection, anti-induction high voltage, anti-surge, etc. IP40 enclosure protection level, able to withstand the test of harsh environments. Specifications: * Fiber Transmission distance: Singlemode single (1 strand) fiber: 20km (12.42mi) * Fiber Transmission Wavelenght: 1310nm/1550 nm (A side) - 1550nm/1310nm (B side) * Fiber Port Datarate - 1000FX or 100FX (easy to set by dip switch) * Status LED indicators for Power, Link/Activity, Full-Duplex, and Speed * Typical transmission power: 1310/1550nm:≥-9dBm * Receiver sensitivity: -28dBm ~ -40dBm * Power Supply Input Range: 9 - 55V DC (but you get a 12VDC/1A power adapter in set) * Power consumption: 5W * Operating temperature -40 ~ +85ºC (-40 ~ +185ºF) * MTBF: 100,000 hours * Dimensions: 60x50x35 mm (L*W*H)Powered by an external power source (DC 9 – 55V), but you will still get a free 2 x AC to DC 12V adapters with every media converter set. Really Small Size (only 60* 50* 35 mm (2.36* 1.96* 1.37in) (L*W*H)), but still Full Duplex Gigabit Ethernet, you get 1 pair (2 units) - A side + B side (1310/1550nm and 1550/1310nm units). Supports LFP (Link Loss Propagation) feature – configurable by dip switch, supports ethernet packet sizes with MTU≥10240, jumbo frames supported. Supports Dual Speed Fiber Mode (configurable by dip switch) – Select 1000Base-FX or 100Base-FX – interconnecting with existing fiber nodes is easy with this media converter. You will need only 1 single mode fiber strand between both sides - set comes with 2 units - A side (1310/1550nm) and B side (1550nm/1310nm) for fully operational link. Small, yet still with DIN rail mount, Industrial Temperature Grade (-40 ºC ~ + 85 ºC), IP40 rated Universal Gigabit 1000FX & Fast Ethernet 100FX Single Mode Single Fiber SC 1310/1550 nm type Fiber Optic Media Converter to Autosensing 10/100/1000Mbit/s Copper Port - 1 pair - A side + B side in packed in same box!.
