With the rapid development of network big data, servers need higher data transmission rate. Most data centers have been upgraded from 10G to 40G. 40G bidi QSFP+ optical module helps to build 40G data center platform. QSFP-40G-SR-BD optical module short distance transmission solution can reuse existing 10G Optical Fiber infrastructure for 40G connection, greatly saving construction cost.

Next, ETU-Link will introduce the parameters and application of QSFP-40G-SR-BD optical module in this blog.

What is QSFP-40G-SR-BD optical module?

The transmission wavelength of QSFP-40G-SR-BD optical module is 850nm and 900nm, and it has two 20gbps optical signal receiving and transmitting channels. Each signal channel can transmit simultaneous transmitting and receiving different transmission wavelengths through a multi-mode optical fiber.

The difference between QSFP-40G-SR-BD and QSFP-40G-SR4:

QSFP-40G-SR4 optical module uses 8 channels to realize 40G transmission, but QSFP-40G-SR-B only needs 2 20g channels to realize this function.

How to connect QSFP-40G-SR-BD?

The transmission wavelength of QSFP-40G-SR-BD optical module is 850nm and 900nm, which can be stably transmitted in multimode optical fiber system. Note that the transmission distance using OM3 fiber patch cord is 100m and the transmission distance using OM4 fiber patch cord is 150m. Yitianguang communication optical module manufacturers can supply a full range of 40G QSFP+ optical module products, providing high-quality transmission solutions for data center network upgrading.

When QSFP-40G-SR-BD optical module is used in the data center to upgrade from 10G to 40G, it is a cost-effective, convenient and quick solution without changing the optical fiber cabling in the previous data center or server room. Yitian can provide customers with a series of cost-effective 40G QSFP+ solutions to meet different cabling needs.
