agilent HFCT-5611U gigabit interface converters (gbic) for extended link lengths (up to 80 km) description the HFCT-5611U interface converter meets the gigabit interface converter specification rev. 5.4, an industry standard. the converter provides a uniform form factor for a wide variety of standard connections to transmission media. the converter can be inserted or removed from a host chassis without removing power from the host system. the converter is suitable for gigabit ethernet applications. the design of this converter is also practical for other high performance, point- to-point communication requiring gigabit interconnections. since the converter is hot-pluggable, it allows system configuration changes simply by the plugging of a different type of converter. the mechanical and electrical interfaces of the converter to the host system are identical for all implementations of the converter regardless of external media type. a 20-pin connector is used to connect the converter to the host system. the hfct- 5611u has been developed with 1550 nm long wavelength dfb laser technology. features ? ieee 802.3z gigabit ethernet with extended link lengths (up to 80 km) compliant with gigabit interface converter specification rev. 5.4 (1) hot-pluggable +5 v power supply uncooled dfb laser eye safety certified: - us 21 cfr(j) - iec 60825-1 (+all) pin receiver sc-duplex fiber connector fiber compatibility: - up to 80 km with 9 m sm fiber applications gigabit ethernet (1.25 gbd) switch to switch interface high speed i/o for file servers ? bus extension applications serial identification the HFCT-5611U complies with annex d (module definition 4) of the gbic specification revision 5.4, which defines the serial identification protocol. definition 4 specifies a serial definition protocol. for this definition, upon power up, mod_def(1:2) (pins 5 and 6 on the 20-pin connector) appear as nc. pin 4 is ttl ground. when the host system detects this condition, it activates the public domain serial protocol. the protocol uses the 2-wire serial cmos e2prom protocol of the atmel at24c01a or similar. the data transfer protocol and the details of the mandatory and vendor specific data structures are defined in annex d of the gbic specification revision 5.4.
2 regulatory compliance see the regulatory compliance table for the targeted typical and measured performance for these transceivers. the overall equipment design will determine the level it is able to be certified to. these transceiver performance targets are offered as a figure of merit to assist the designer in considering their use in equipment designs. electrostatic discharge (esd) there are two design cases in which immunity to esd damage is important. the first case is during handling of the transceiver prior to inserting it into the host system. it is important to use normal esd handling precautions for esd sensitive devices. these precautions include the use of grounded wrist straps, workbenches, and floor mats in esd controlled areas. the second case to consider is static discharges during insertion of the gbic into the host system. there are two guide tabs integrated into the 20-pin connector on the gbic. these guide tabs are connected to circuit ground. when the gbic is inserted into the host system, these tabs will engage before any of the connector pins. the mating connector in the host system must have its tabs connected to circuit ground. this discharges any stray static charges and establishes a reference for the power supplies that are sequenced later. electromagnetic interference (emi) most equipment designs utilizing these high-speed transceivers from agilent will be required to meet the requirements of fcc in the united states, cenelec en55022 (cispr 22) in europe and vcci in japan. immunity equipment utilizing these transceivers will be subject to radio-frequency electromagnetic fields in some environments. these transceivers have good immunity to such fields due to their shielded design. caution: there are no user serviceable parts nor any maintenance required for the HFCT-5611U. all adjustments are made at the factory before shipment to our customers. tampering with or modifying the performance of any agilent gbic unit will result in voided product warranty. it may also result in improper operation of the circuitry, and possible overstress of the semiconductor components. device degradation or product failure may result. connection of the HFCT-5611U to a non- approved optical source, operating above the recommended absolute maximum conditions, or operating in a manner inconsistent with unit design and function, may result in hazardous radiation exposure and may be considered an act of modifying or manufacturing a laser product. the person(s) performing such an act is required by law to recertify the laser product under the provisions of us 21 cfr (subchapter j).

4 eye safety design the laser driver is designed to be class 1 eye safe (cdrh21 cfr(j), iec 60825-1) under a single fault condition. there are three key elements to the safety circuitry: a monitor diode, a window detector circuit, and direct control of the laser bias. the window detection circuit monitors the average optical power using the photo diode in the laser osa. if a fault occurs such that the dc bias circuit cannot maintain the preset conditions within 20%, tx_fault (pin 10) will be asserted (high). note: under any single fault, the laser optical output power will remain within class 1 eye safe limits. optical receiver pecl driver optical transmitter pecl receiver serial eeprom hot plug control +rx_dat -rx_dat +tx_dat -tx_dat rx_los tx_disable tx_fault mod_def(0) mod_def(1)/scl mod_def(2)/sda v ddr v ddt optical interface duplex sc connector electrical interface 20 pin sca-2 connector r gnd t gnd figure 1. block diagram
