Description:

BDTRP413L1SD-20 Small Form Factor Pluggable (SFP)
transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing
Agreement (MSA).They comply with
laser safety standard
IEC-60825
and Ethernet standard
IEEE802.3z 1000Base-LX/LH and IEEE802.3ah.

The transceiver consists of two sections: The transmitter
section incorporates a FP laser. the receiver section consists of a PIN
photodiode integrated with a trans-impedance preamplifier (TIA).

All modules satisfy class I
laser safety requirements. The optical output can be disabled by a TTL logic
high-level input of Tx Disable.  Tx Fault
indicates that degradation of the laser. Loss of signal (LOS) output indicates the
loss of an input optical signal of receiver.
The SFP module can be compatible with other brand switch
devices like Cisco,Huawei etc.The SFP module has the function of AGC
(Automatic
Gain control without attenuator).

Notes:

1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.

2. Also specified to meet curves in FC-PI 13.0 Figures 18 and 19, which
allow trade-off between

wavelength, spectral
width and OMA.

3. Equivalent extinction ratio specification for Fiber Channel. Allows
smaller ER at higher average power.

4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye
masks when filtered.

5. Measured with DJ-free data input signal. In actual application, output
DJ will be the sum of input DJ and DDJ.

6. Measured with conformance signals defined in FC-PI 13.0 specifications.
7. Measured with PRBS 27-1 at 10-12 BER
