Description
The DTR-1250-SM-GB-H8-HS-CWDM-MR product
family of multi-rate GBICs provides a very long haul,
single mode solutions for 1000BASE-LX Gigabit Ethernet
and 1.062GBd Fibre Channel ports in a networking
switch. The transceivers are designed to support data rates
ranging from 1250Mb/s down to 125Mb/s and are available
in eight (8) wavelengths: 1470nm, 1490nm, 1510nm,
1530nm, 1550nm, 1570nm, 1590nm and 1610nm. The
transceivers use a 1550nm DFB laser and an ultra high
sensitivity Avalanche Photodiode (APD) receiver to provide
a minimum optical link power budget of 33dB which
corresponds to a transmission distance of 120km, assuming
a total connector/splice/CWDM mux and demux loss of
4.6dB, allocated system penalty of 2dB and fiber loss of
0.22dB/km. All transceivers are Class I Laser products per
U.S. FDA/CDRH and Class 1M Laser products per
international IEC-60825 standards.
The DTR-1250-SM-GB-H8-HS-CWDM-MR 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
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).
TX_DISABLE: When the TX_DISABLE pin is at logic HIGH,
the transmitter optical output is disabled (less than -35dBm).
Serial Identification: The DTR-1250-SM-GB-H8-HS-CWDMMR 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 negative edge clocks data
from the GBIC EEPROM.
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.
RX_LOS: The RX 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.

The indicated transmission distance is for guidelines only, not guaranteed. The exact distance is dependent on the fiber loss, connector/splice/
CWDM mux and demux loss and allocated system penalty. Longer distances can be supported if the optical link power budget is satisfied.

Assuming a total connector/splice/CWDM mux and demux loss of 4.6dB, allocated system penalty of 2dB and fiber loss of 0.22dB/km.
