| HG Genuine GBIC Transceiver MGB-243S GBIC Transceiver MGB-243S Features Operating temperature range 0C to +70C Operating bit rate 1250Mbps Hot-pluggable capability. Low power dissipation 1310 nm FP laser SCA-2 electrical interface Single 3.3V/5V power supply Differential PECL input and output TTL signal detect indicator Duplex SC optical interface Detailed product information in E2PROM Applications Gigabit Ethernet Switch to Switch interface Router/server interface Other optical transmission systems Description: MGB-243S is compliant with Gigabit Interface Converter (GBIC) specification Rev5.5. It meets the requirements of IEEE 802.3 Gigabit Ethernet standard and ANSI specifications for fiber channel. It can be inserted in or removed from host chassis without shutting power of the host system. MGB-243S Operating Wavelength is 1310nm, it enables cost-effective data transmission over optical fibers at a distance of 10 km. The operating voltage is +3.3V or +5V.

MGB-243X complies with Module Definition 4. It features an EEPROM that contains the detailed product 3of7 HG Genuine GBIC Transceiver MGB-243S information stored for retrieval by host equipment. This information is accessed via the 2-wire serial CMOS EEPROM protocol of ATMEL AT24C01A. TX_Fault When sensing an improper power level in the laser driver, the GBIC set this signal high and turns off the Laser. TX_FAULT can be reset with the TX_DISABLE line. The signal is in TTL level. TX_Disable The TX_DISABLE signal is high (TTL logic "1") to turn off the laser output. The laser will turn on within 1ms when TX_DISABLE is low (TTL logic "0"). Receive Loss (RX_LOS) The RX_LOS is high (logic "1") when there is no incoming light from the companion transceiver. This signal is normally used by the system for the diagnostic purpose. The signal is operated in TTL level. Figure 2 shows the internal frame of GBIC, Figure34 show the typical eye diagrams of this product.
