Optical Fiber Modem/Media Converter             AiSai AiSai ASO FOM-FE1 / FOM-V.35 Optical Fiber Modem The FOM-FE1 and FOM-V.35 fiber optic modem are designed to transmit high speed data over a pair of single mode fiber optic cable and work on connection of PABX, routers or other networking devices with distance from 5 to 100km. Single core optical transceiver for single fiber network is available for order. FOM-FE1 that supports fractional E1 ( Nx64 Kbps ) with G.703 interface and FOM-V.35 that supports transmission speed of 64Kbps up to 2.048 Mbps with V.35 data interface. Data speed rate is defined via the DIP switches located on the bottom of the equipment. LED indicators are equipped on the front panel for the interfaces and transmission statues. Built-in BER tester and loopback facility for local and remote is achieved from the push button on front panel. The design of the modem is high compact and operation is simplified.   Key Features     • G.703 fractional E1 or V.35 port • Selectable data speed • Single core transceiver is available • Front panel LED indicators   • Built-in BER tester • Local and remote loopback facility • Support AC or DC power supply               Specifications     Optical Interface   E1 Interface     Wavelength: 1310nm/1550nm (option) Light Source: Single Mode Laser Connector: FC / SC Line Coding: 5B6B Line Rate: 121.651 Mbps   Standard: ITU-T G.703/G.704 Data Rate: 2.048Mbits +/- 50ppm Line Code: HDB3 Connector: BNC, Coaxial (75 ohm),                    RJ48 (120 ohm) Jitter/wander: ITU-T G.823     Dual Core Fiber Transceiver   V.35 Interface     Tx Power: > - 12 dBm Rx Sensitivity: < - 36 dBm (BER<=10-10) Link Budget: 24 dBm   Standard: V.35 Data Rate: n x 64Kbps (n=1~32) Clock Mode: Internal, External, Line     Single Core Fiber Transceiver   Power Supply     Multiplexer: WDM Tx Power: > - 14 dBm Rx Sensitivity: < - 32 dBm (BER<=10-10) Link Budget: 18 dBm     AC Power: 220V Range: 180 ~ 240V DC Power: -48 V or +24 V Range: -38 ~ -72V or +18 ~+36V Consumption: <5W     Environment   Mechanical     Working Temp: 0 ~ 50 oC Storage Temp: -40 ~ +75 oC Humidity: <95%   Dimension: 215 x 150 x 40mm                   AiSai ASC-100-E/FE-B-V V.35/Ethernet to E1 Interface Converters Cater to the multi-services requirement by the digital data network, Aisai designs and manufactures a series of interface converter that perform the conversion from V.35 or Ethernet signals to the 2Mbps structured (framed) or non-structured (unframed) E1 G.703/G.704 data signal. The ASC-100-E/V and ASC-100-FE/V perform data signal conversion from V.35 data to E1 signal. The ASC-100-E/V provides transparent transport to the E1 network and ASC- 100-FE/V supports nx64Kbps with structured or non-structured mode transport. The V.35 converter works as a bit rate adapter and the ASC-100-FE/V follows the frame recommended in ITU-T G.704. The framing can be deactivated and resulting in a trans- parent 2.048 Mbps converters (n=1 to 32). The ASC-100-E/B and ASC-100-FE/B perform data signal conversion from 10/100BaseT Ethernet and bridge over the E1 network. The ASC-100-E/B provides transport to the E1 network transparently and ASC-100-FE/B supports nx64Kbps with structured or non- structured mode transport. The Ethernet converter supports TCP/IP bridging and MAC address auto learning. It pro- vides user defined dual 120 ohm and 75 ohm E1 interfaces and 10/100BaseT (speed rate auto sensing) / RJ45 Ethernet interface. The ASC-100-CS is a standard 19" rack mounting shelf for different types of converter and supports hot standby dual AC/DC power suppliers. The management control card, NMS-CC which support SNMP manage control. (Remark: Non-structured (unframed) transport will not support remote system control, since all the bandwidth are used for transparent data transportation.)   Key Features     • Provides 75ohm (BNC) and 120ohm (RJ48    /RJ45) dual E1 ports • V.35 converters provide built-in BERT with    local and remote loopback button on front    panel • V.35 converters support internal, external    and slave clocking mode   • Front panel LED indicators for working    status • Ethernet converters provide learning    bridge and MAC address filtering and    support 10/100Mbps speed rate auto    sensing               Specifications     Standalone Model     ASC-100-E/B ASC-100-FE/B ASC-100-E/V ASC-100-FE/V ASC-100-E/VM ASC-100-FE/VM   10/100BT (RJ45) / 2Mbps E1 converter 10/100BT (RJ45) / Nx64Kbps (N=1-32) converter V.35 (DB25) / 2Mbps E1 converter V.35 (DB25) / Nx64Kbps (N=1-32) converter V.35 (M34) / 2Mbps E1 converter V.35 (M34) / Nx64Kbps (N=1-32) converter     Central Shelf Model     ASC-100-E/B-00C ASC-100-FE/B-00C ASC-100-E/V-00C ASC-100-FE/V-00C ASC-100-CS ASC-100-NMS-CC ASC-100-PWU-48D ASC-100-PWU-220A   10/100BT (RJ45) / 2Mbps E1 card set 10/100BT (RJ45) / Nx64Kbps (N=1-32) card set V.35 (DB25) / 2Mbps E1 card set V.35 (DB25) / Nx64Kbps (N=1-32) card set Central management shelf (12 converter cards) Network management card (SNMP agent) -48V DC power module 220V AC power module     E1 Interface   10/100 BT Ethernet Interface     Standard: ITU-T G.703 / G.704 Date Rate: 2.048Mbps +/- 50 ppm (E/V, E/B)                    N x 64 Kbps (N=1~32) (FE/V, FE/B) Frame Mode: PCM30 and PCM31 (FE/V) Line Coding: HDB3 Connector: BNC Coaxial/75 ohm, RJ48/120 ohm   Standard: IEEE802.3 Connector: RJ45 Speed Rate: 10/100Mbps auto-sense Operation Mode: Full / half duplex         Single Core Fiber Transceiver   Power Supply     Multiplexer: WDM Tx Power: > - 14 dBm Rx Sensitivity: < - 32 dBm (BER<=10-10) Link Budget: 18 dBm     AC Power: 220V Range: 180 ~ 240V DC Power: -48 V or +24 V Range: -38 ~ -72V or +18 ~+36V Consumption: <5W     Environment   Dimension     Working Temp: 0 ~ 50 oC Humidity: 95 % non condense   WxDxH (mm): 230x155x45 (Standalone unit)                        432x257x178 (Central Shelf)
