Description
The DTR-1250-SM-GB-I product family of GBICs provides
long haul, single mode solutions for 1000BASE-LX Gigabit
Ethernet ports in a networking switch. OCP offers four
distance options to support 42km, 68km, 72km and 80km
links in the networking infrastructure. Option “H3” uses a
1310nm DFB laser and provides a minimum optical link
budget of 19dB, corresponding to a minimum distance of
42km, assuming fiber loss of 0.35dB/km. Options “H5”,
“H7” and “H8” use 1550nm DFB lasers, and provide
minimum optical link budgets of 21dB, 22dB and 24dB
respectively. Each corresponds to minimum distances of
68km, 72km and 80km respectively, assuming fiber loss
of 0.25dB/km. All transceivers are Class I Laser products
per U.S. FDA/CDRH standards. The “H3”, “H5” and “H7”
transceivers are Class I Laser products while the “H8”
transceivers are Class 1M Laser products per international
IEC-825 standards.
The DTR-1250-SM-GB-I transceivers are fully compliant
with Annex F of GBIC specification, Rev. 5.5 (except for
higher TX optical power and 1550nm center wavelength
option).
The transceivers connect to standard 20-pad GBIC
connectors for hot plug capability. This allows the system
designer to make configuration changes or maintenance
by simply plugging in different types of GBICs without
removing the power supply from the host system.
The transceivers operate from a single +5V power supply
over an operating case temperature range of -5°C to +70°C.

Application Notes
TX_DISABLE: When the TX_DISABLE pin is at logic HIGH,
the transmitter optical output is disabled (less than -35dBm).
Connection of the GBIC transceiver to the host system: The
GBIC’s 20-pad connector and two guide tabs connected to the
transceiver’s circuit ground connect the GBIC to the host
system. The two ground tabs make contact to the host circuit
ground before the connector pad and discharge any possible
component-damaging static electricity. Additionally, surge
currents are eliminated by using a special slow start circuit
and two-stage contact sequence where operational signals and
grounds make contact prior to the power supply (as specified
in the GBIC specification, Rev. 5.5).
Serial Identification: The DTR-1250-SM-GB-I transceivers
are compliant with Annex D (Module Definition 4) of the GBIC
specification, Rev. 5.5, which defines the Serial Identification
Protocol.
The module definition of GBIC is indicated by the three module
definition pins, MOD_DEF(0), MOD_DEF(1) and MOD_DEF(2).
Module Definition 4 specifies a serial definition protocol with
a two-wire I2C serial interface; upon power up, MOD_DEF(1:2)
appear as NC (no connection), and MOD_DEF(0) is TTL LOW.
When the host system detects this condition, it activates the
serial protocol and generates the serial clock signal (SCL). The
positive edge clocks data into the EEPROM segments of the
GBIC that are not write protected, and the negative edge clocks
data from the GBIC.
Electrical interface: All signal interfaces are compliant with
the GBIC specification, Rev. 5.5. The high speed DATA
interface is differential AC-coupled and can be directly
connected to either a 5V or 3.3V SERDES IC. All low speed
control and sense input/output signals are open collector TTL
compatible and should be pulled up with a 4.7 - 10kΩ resistor
on the host board.
The serial data signal (SDA) is for serial data transfer. The host
uses SDA in conjunction with SCL to mark the start and end of
serial protocol activation.
Loss of Signal (LOS): The Loss of Signal circuit monitors the
level of the incoming optical signal and generates a logic HIGH
when an insufficient photocurrent is produced.
The data transfer protocol and the details of the mandatory and
vendor specific data structures are defined in Annex D of the
GBIC specification, Rev. 5.5.
TX_FAULT: The output indicates LOW when the transmitter
is operating normally, and HIGH when the transmitter or laser
current is excessive. TX_FAULT is an open collector/drain
output and should be pulled up with a 4.7 - 10kΩ resistor on
the host board.
Power supply and grounding: The power supply line should
be well-filtered. All 0.1µF power supply bypass capacitors
should be as close to the GBIC transceiver module as possible.
