INFORMATION
Description:
The
SFP-BIDI transceivers are high performance, cost effective modules supporting
dual data-rate of 2.5Gbps/2.125Gbps and 20km transmission distance with SMF.
The
transceiver consists of three sections: a DFB laser transmitter, a PIN
photodiode
integrated
with a trans-impedance preamplifier (TIA) and MCU control unit. All modules
satisfy
class
I laser safety requirements.
The
transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472.
For further information, please refer to SFP MSA.
FEATURES:
- Dual
data-rate of 2.5Gbps/2.125Gbps operation
- 1550nm DFB

Notes:
1. Circuit ground is internally isolated from chassis
ground.
2. Laser output disabled on TDIS >2.0V or open,
enabled on TDIS <0.8V.
3. Should be pulled up with 4.7k - 10 kohms on host board
to a voltage between 2.0V and 3.6V. MOD_DEF(0) pulls line low to indicate
module is plugged in.
4. BDTRP413L1SN-20 transceivers
operate between OC-3 and OC-48, 1x and 2x Fiber Channel, and Gigabit Ethernet
data rates and respective protocols without active control. BDTRP413L1SN-20 transceivers
operate at 1x and 2x Fiber Channel, and Gigabit Ethernet data rates and
respective protocols without active control.
5.
LOS is open collector output. Should be pulled up with 4.7k – 10 kohms on host
board to a voltage between 2.0V and 3.6V. Logic 0 indicates normal operation;
logic 1 indicates loss of signal.

6. LOS is LVTTL. Logic 0 indicates normal operation;
logic 1 indicates no signal detected.
7. All transceiver specifications are compliant with a
power supply sinusoidal modulation of 20 Hz to 1.5 MHz up to specified value
applied through the power supply filtering network shown on page 23 of the
Small Form-factor Pluggable (SFP) Transceiver MultiSource Agreement (MSA),
September 14, 2000.
8. Measured with DJ-free
data input signal. In actual application, output DJ will be the sum of input DJ
and DDJ.
