Description:
BDTRP439S1SN/D-20 Small Form Factor Pluggable (SFP) transceivers are compatible with the Small
Form Factor Pluggable Multi-Sourcing Agreement (MSA). The SFP transceiver supports dual data-rate of 1.25Gbps
and from 20km transmission distance with SMF. They simultaneously comply with the standards IEEE
Std 802.3 and IEEE 802.3u. 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).
