Overview                                                                             The Gigabit Ethernet Media Converters with external power supply are designed to transmit and receive 10/100/1000Mbps data over optical fiber. The electrical interface will Auto-Negotiate to a 100Mbps or 1000Mbps Ethernet rate without any adjustments. The optical interface operates at a 1000Mbps Ethernet rate. Both are environmentally hardened to operate in extreme temperatures. LED indicators are provided for confirming equipment operating status.       Please note:                          2.  Default with EU power adapter.UK,US,BR,AU standards can be provided as request.         3.Bulk order please contact with us , we are factory have the best price for you.        Feature:     1.  High Quality, 2 years quality guarantee      2.  An RJ45 ports and a single-fiber SC optical port , to achieve optical signal conversion between 10/100base TX twisted pair          (Ethernet )and 100base FX (fiber optic) ;     3.  Core optical fiber can be completed in just one way signal transmission compared to dual fiber optic data transmission           mode to improve the quantity doubled ;     4.  Compliance with IEEE802.3 10Base-T and IEEE802.3u 100Base-TX, 100Base-FX standards ;     5.  Has 10M/100M adaptive capacity ;     6.  Ethernet interface can adaptively direct line / crossover cable connection ;     7.  Support full / half duplex mode ;     8.  Support IEEE802.3X duplex flow control and half-duplex backpressure flow control ;     9.  Supports broadcast storm prevention function ;     10. 1916 Byte support large data frame ( optional ) ;     11.  Built- in lightning protection circuit , which can greatly reduce the damage caused by lightning induction ;     12.  UTP up to 100 meters ; longest 100 km single-mode fiber ;     13.  There are six LED indicators : Power, TX 100, TX Link / Act, FX 100, FX Link / Act, FDX / Col; easy to monitor the working            status of the transceiver and determine the cause of the fault ;     14.  There are external , internal power supply of two types : AC100 ~ 265V / DC5V switching power supply ;     15.  Working temperature : 0 ~ 50 degree;     16.  Storage temperature : - 40 ~ 70 degree ;     17.  Transceiver Dimensions: External power 70 × 26 × 93mm; built-in 120 × 30 × 140mm.     18.  outer Dimensions: 95mm × 71mm × 25mm     19.  Package: ESD package,Carton
