Description
Class I Laser products per U.S. FDA/CDRH standards.
The “H7” transceiver is Class I Laser product while the
“H8” transceiver is Class 1M Laser product per international
IEC-825 standards.
The DTR-1250-SM-GB-HS product family of GBICs
provides very long haul, single mode solutions for
1000BASE-LX Gigabit Ethernet ports in a networking
switch. OCP offers two optical link power budget options
to support 110km (H7) and 120km (H8) in the networking
infrastructure. Both options use 1550nm DFB lasers and
ultra high sensitivity Avalanche Photodiode (APD) receivers
to provide minimum optical link power budgets of 30dB
and 32dB. They correspond to transmission distances of
110km and 120km, respectively, assuming a total
connector and splice loss of 2dB, total system penalty of
3dB and fiber loss of 0.22dB/km. All transceivers are
The DTR-1250-SM-GB-HS 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-HS 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 and
splice loss and allocated system penalty. Longer distances can be supported if the optical link power budget is satisfied.
