Introduction JHA-F11U Series Fiber Media Converters can convert Optical - Electric Ethernet signals between 10/100M UTP interface (TX) and 100M optical fiber interface (FX).  It can extend traditional 10/100M fast Ethernet to the distance of 120km through optical fiber link. It possesses stable performance and good quality by adopting latest IC packages from USA and Taiwan. 6 Group LED indicated lights could fully monitor the working conditions of Converters. It is easy for end-users to observe network operation. DM02/DS02 series external power supply Converters could be used alone, or inserted to 14 slots Converters Rack. It is suitable for the use of Network Centre. JHA-F11U series can support USB power supply, which make fiber to table more convenient. Having 5 DIP switch, JHA-F11U series make customer easier to manage the items.  Features ♦ Auto negotiation function allows UTP port to auto select 10M or 100M, and Full Duplex or Half Duplex. ♦ UTP port supports MDI/MDI-X auto crossover. ♦ LFP (Link Fault Pass-through): When optical fiber or UTP is at fault, the converter could stop all the link. ♦ Multiple Optical Transceiver could be chosen: SC, ST or FC, singlemode / multimode ♦ Supporting 1600 bytes packet for management   ♦ Converter working mode could be chosen: Store and forward switch mode, Modified cut-through switch mode, or Converter mode. ♦ Internal Circuit of prevented thunder could greatly reduce damage of the converter caused by thunderbolt induction. ♦ Internal or External switching power: for users to choose. ♦ DIP SWITCH   Switch Function Switch Function Switch 1 Auto UTP Nway Force UTP optional Switch 2 100 UTP100M 10 UTP10M Switch 3 FDX UTP Full Duplex HDX UTP Half Duplex Switch 4 LFP LFP available LFP DIS LFP Not available Switch 5 FDX Optical Full Duplex HDX－FX Optical Half Duplex Switch 6 FDX Converter model SW Switch model Specification ♦ Operating standards:IEEE802.3u、10/100Base-TX and 100Base-FX；. ♦ MAC addresses table: 1K ♦ Data buffer: Built-in 128Kbyte RAM . ♦ Connectors: UTP Connector: RJ-45, 10/100Mbps;  Fiber Connector: ST/SC/FC, 100Mbps ♦ Cable: UTP: Cat. 5 (the max distance up to 100m) Fiber ( Multimode): 50/125, 62.5/125μm（the max distance up to 2km or 5km） Fiber ( Singlemode): 8.3/125, 8.7/125, 9/125, 10/125μm（the max distance up to 20 -120km） ♦ Flow Control Full Duplex: Supporting standard IEEE802.3x Half Duplex: back pressure ♦ LED: Power, FX SD, FX Link/Act, TX 100, TX FDX, TX Link/Act. ♦ Power Requirement: External Power supply     Input:85-245VAC 50Hz or DC 48V Output:5VDC 1A USB power supply:5VDC 1A ♦ Ambient Temperature: 0 ～ 70℃ ♦ Humidity: 5 ～ 90% ♦ Dimensions: 26×70×93mm ♦ External power: yes Order Information Model No. Description of Goods JHA-F11U 10/100M Multimode, Dual Fiber, 2Km, SC/ST/FC/LC Connector JHA-F11U-20 10/100M Single-mode, Dual Fiber, 20Km, SC/ST/FC/LC Connector JHA-F11WU-20 10/100M Single-mode, Single Fiber,20Km, SC/ST/FC/LC Connector JHA-FS11U 1*100Base-X SFP Slot + 1*10/100Base-T(X) RJ45 Port
