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:
- Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
- Also specified to meet curves in FC-PI 13.0 Figures 18 and 19, which allow trade-off between
wavelength, spectral width and OMA.
- Equivalent extinction ratio specification for Fiber Channel. Allows smaller ER at higher average power.
- Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
- Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ andDDJ.
- Measured with conformance signals defined in FC-PI 13.0 specifications.
