the reseller is a Cisco SFP 1.25G brand among many others

The receiver section of optical SFP uses a PIN receiver and the transmitter uses the most of common FP or DFB lasers, which allow up to 1.25Gbps rates over 500M ~ 120Km Ethernet applications. The Cisco SFP 1.25G and XFP consist of 10Gbit/s DFB/ EML optical transmitter and PIN receiver, All modules satisfy class I laser safety requirements.The transceivers are compatible with SFP Multi-Source Agreement (MSA) and SFF-8472.Those content above is detail information of [Gigabit Ethernet Cisco SFP 1.25G WITH DDM , Compatible Cisco / HP / Finisar], If you want to get more information about product price,type,function and so on, Please contact us soon. RB2011 supports any 1.25G SFP transceivers that is within the SFF Committee specifications for SFP Transceivers. RB2011LS doesn’t have hardware support for PON (Passive Optical Network) - this hardware support MUST be implemented on SFP transceiver itself.The digital diagnostic monitoring function is fully compliant with SFP MSA. The module consists of 1490nm DFB Laser, APD detector and WDM filter in a high-integrated optical sub-assembly.

It transmits 2.488Gbps at 1490nm, and receives 1.244Gbps at 1310nm in burst mode. It is sold as pictured and doesn't include any additional parts or accessories.The Cisco SFP 1.25G optical module is Small Form Factor Pluggable (SFP) transceivers are compatible with the Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). They simultaneously comply with Gigabit Ethernet as specified in with SMF IEEE Std 802.31 and 1x and 2x Fiber Channel as defined in FC-PI 13.03.SFP transceivers support communications standards including synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), gigabit ethernet and fiber channel. They also allow the transport of fast Ethernet and gigabit Ethernet LAN packets over time-division-multiplexing-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks.SFP units like the GLC-LH-SM in general have different transmitter and receiver types that allow the consumer to select the best option for their specific situation. Its primary function is to interface with a networking cable and increase the connectivity between two network devices such as mother boards, routers and media converters.
