HTF‘s 100G QSFP28 BIDI 20km & 100G QSFP28 BIDI 30km single-fiber optical transceiver module is an optical transceiver module designed for single-channel optical transmission of 20km and 30km or more. The module contains a single channel optical signal and operates at 100Gbps data rate. Converts 4x25Gb/s (4x28Gb/s) NRZ electrical input data into a single optical signal for 100Gb/s optical transmission. Conversely, at the receiving end, converts 100Gb/s optical input data into 4x25Gb/s (4x28Gb/s) NRZ electrical output data. Next, let’s take a look at the advantages of 100G QSFP28 BIDI 20km & 100G QSFP28 BIDI 30km single fiber optical transceiver module products:

1. We all know that conventional optical fiber transmission is single-fiber and unidirectional. To achieve two-way communication, two optical fibers are needed. Compared with the two, BIDI technology only requires one optical fiber, which means that the transmission capacity of the existing optical fiber is reduced. It has been doubled, thus saving fiber resources.

2. In addition, dual-fiber optical modules have only one wavelength, usually 850nm, 1310nm, 1550nm, etc. The single-fiber optical module has two different wavelengths. Since the wavelength used by BIDI optical modules does not produce a large dispersion penalty, there is no other difference in transmission indicators from dual-fiber bidirectional optical modules, and it has obvious advantages in cost and does not require additional maintenance and management. Therefore, the optical fiber direct connection solution The use of single-fiber bidirectional modules is the best choice. At the optical module level, BIDI optical modules and colored optical modules can improve fiber utilization to a certain extent, and are also a good cost-saving choice for users.

3. HTF 100G QSFP28 BIDI single-fiber optical module can be fully compatible with existing switch interfaces, saving costs.

4. The transmitter and receiver of the 100G QSFP28 BIDI single-fiber optical module only use one optical chip each. The product design is simpler, which not only reduces device costs, but also reduces production and manufacturing costs.
