SFP BiDi 1000BASE-BX 1.25Gbps Tx1550nm/ Rx1310nm LC SMF DDM 20km

The LightOptics LO-SF-1G-5S3-20L -SFP BiDi 1.25Gbps Tx 1550nm Rx 1310nm LC SMF DDM 20km optical module supports single mode WDM fiber (simplex transmission over a single fiber), transmitting data at speeds up to 1.25Gbps, maximum distance up to 20km. TX transmitter – DFB 1550nm laser, RX receiver – PIN photodetector 1310nm. LC/UPC optical connector.

Pairs with: LO-SF-1G-3S5-20L

For connection over a single fiber (1J), the wavelength of the transmitter is cross-selected, so that the TX value from one side corresponds to the RX value on the other side. For easier identification, the handles of the transceivers are labelled with different colors, for example blue and green, blue and yellow, blue and violet.

The transceivers support the WDM technology, which provides bidirectional (Bi-Di) transmission over one single-mode 9/125μm optical fiber and operate on two different wavelengths: 1310nm and 1550nm.

Application  

LightOptics modules are perfect for devices such as switches, converters, routers or servers from the majority of manufacturers available on the market, thanks to the constantly growing compatibility that adapts to new products and changing software.  

LightOptics SFP 1000Base-BX modules are versatile and work reliably at distances of up to 20km but also on very short links. You can connect them with a patch cable as short as 1m without fear of damaging the laser, thanks to the special design of the receiving diode.  

No more hassle with transceiver detection  

Why should you invest in LightOptics SFP modules?   

• You receive a compatible transceiver that your switch, converter, server or router can detect seamlessly.  
• This model is characterized by the notable reliability of its components, which translates to its repeatable compatibility.
• You get a transceiver that works steadily and does not overheat.  
• Additionally, you will receive a control tool for your network: The built-in DDM diagnostic module, which will allow you to monitor the transceiver’s parameters in real time: input and output optical power, temperature, voltage and current.  

LightOptics offers excellent quality for a reasonable price. Our products are manufactured in compliance with the MSA Specification They are compliant with professional standards, as well as all electrical and electromagnetic requirements.

Proven quality, rigorous testing  

High quality and repeatability for the safe and steady operation of your network – that's our goal.

The compatibility of the module is the effect not only of its programming, but also of the high standards of the production process. Our engineers adapt the transceivers to work with various networking devices, and ensure their seamless detection in switches, routers, servers or interface cards. The reliability of the transceivers is proven with rigorous testing.

LightOptics modules are perfect for devices such as switches, converters, routers or servers from the majority of manufacturers available on the market, thanks to our adaptability to new products and changing software. 

Diagnostics of your Network  

The DDM diagnostic module enables real time monitoring of the operating parameters of your transceiver, for example, the input and output optical power, temperature, voltage or current. Be in control over your network and prevent malfunctions thanks to quick and easy diagnosis of the network, with no additional equipment needed.   

To get access to the DDM diagnostics, both the transceiver and the device must possess the DDM function, sometimes called DOM (nearly all managed devices are equipped with this function).
