As we all know, the 40G SR4 QSFP+ optical module is the ideal solution for short-range interconnection in 40G networks and has many advantages, but the 40G QSFP+ AOC also has similar function of optical module and is not inferior to the 40G SR4 QSFP+ module or even can replace it to transmit signals. Since both can be 40G short-distance interconnection, then what are the differences between them? ...

BIDI optical module only has one optical port, just need one fiber can simultaneously transmit and receive optical signals, is a solution to save fiber resources. BIDI optical module uses WDM technology to realize the bidirectional transmission of optical signals on one optical fiber. Optical module usually has two ports, the TX is the transmitting port, and the RX is the receiving port. BIDI modu...

If you are the first time to buy optical transceivers, you might be confused with "DDM", "DOM" or "RGD". What are they? Today, ETU-Link will describe in detail the functions of these three types of optical modules. What is DDM? DDM means Digital Diagnostic Monitoring. It is the technique used in the optical module so that users can monitor the real-time parameters of the module. Including modules’...

The time is flying! There are less than three months left in 2018, and some maybe feel that time is too slow and some will feel that time is too fast.The big family of ETU is expanding day by day, from the beginning of the trading company to own its own production line, from more than 100 square meters to more than 1,000 square meters of plant, from a few employees to dozens of employees, in just ...
