Calculate the bit error rate using bits
In, the number of bit errors is the number of received of a over a that have been altered due to,, or errors.

Principle of Bit Error Rate Tester
BERT or bit error rate test is a testing method for digital communication circuits that uses predetermined stress patterns consisting of a sequence of logical ones and zeros generated by a test pattern generator. It involves measuring the rate at which errors occur in a transmitted bitstream compared to the expected bitstream at the receiver end. BERT measures the pattern sensitivity to characterize the BER (Bit Error Ratio or Bit Error Rate) of digital systems.

155m Optical Module Model Description
Supports up to 155Mbps bit rates Hot-pluggable SFP footprint 1310nm FP laser and PIN photo detector, Up to 20km for SMF transmission Compliant with SFP MSA and SFF-8472 with single LC receptacle Compatible with RoHS Single +3. The SFP-155M transceiver family are small form factor pluggable modules for bi-directional serial optical data communications such as SONET/SDH OC-3/STM-1 or Fast Ethernet. Starting from V800R025C00SPC500, this optical module supports three interface modes: STM1, STM4, and STM16. The 155M DDM SFP Module offers Digital Diagnostic Monitoring (DDM) for real-time performance monitoring and troubleshooting. Despite the dominance of Gigabit and 10G optics, 155M SFP modules are still actively purchased today —not as legacy leftovers, but as deliberate, cost-efficient. Supporting 2km transmission over multimode fiber at 1310nm wavelength, this dual-rate 100/155M SFP module provides 14 dB link budget with speeds from 100-155Mbps.

Power Supply Unit Model for Computer Room
When motherboard and graphics-card manufacturers started powering CPUs and GPUs from separate 12-volt connectors, many older power supplies were still designed to put out a substantial portion of their amperage to 5-volt and eve. That led to widespread advice and articles recommending wildly exaggerated power-supply ratings to cover. Power supplies, as we know them in desktop PCs, go all the way back to the original IBM PC. 80 Plus is a power-supply certification program that guarantees a minimum of 80% efficiency across a wide variety of loads, with different levels offering increased energy savings via reduced PSU waste heat.
