BiDi SFP (Bidirectional Small Form-Factor Pluggable) transceivers are designed to transmit and receive data over a single fiber optic cable. They use wavelength division multiplexing (WDM) technology, where different wavelengths are used for upstream and downstream communication on the same fiber.1.25G SFP BIDIThe specific wavelengths used for BiDi SFPs can vary depending on the implementation and

LR (Long Range) and SR (Short Range) are terms commonly associated with optical transceiver modules, particularly in the context of fiber-optic communication. These designations help indicate the intended reach or distance of the transceiver. Here are the key differences between LR and SR transceivers: Reach or Distance:LR (Long Range): LR transceivers are designed for longer-distance transmi

PSM4 (Parallel Single Mode 4) and SR4 (Short Range 4) are both optical transceiver technologies used in data center and high-performance computing environments, but they have key differences:Fiber Type:PSM4: PSM4 transceivers use single-mode fiber (SMF). Single-mode fiber is designed for longer-distance transmission and is capable of carrying signals over larger distances with lower attenuation.SR

QSFP+ (Quad Small Form-factor Pluggable Plus) and QSFP28 (Quad Small Form-factor Pluggable 28) are both types of transceiver modules used in high-speed data communication applications, particularly in data centers and high-performance computing environments. The primary difference between them lies in the maximum data rate they support:QSFP+:Data Rate: Supports data rates up to 40 gigabits per sec

It seems there might be a confusion in your question. DR4 and FR4 typically refer to different things, and they are not directly comparable.DR4:Digital Radiography (DR): DR commonly stands for Digital Radiography in the medical field. It is an advanced form of X-ray imaging that uses digital sensors to capture and display X-ray images in real-time.FR4:FR4 (Flame Retardant 4): FR4 is a grade design
