Description

SPT-QSFP-SR4 is a Four-Channel, Pluggable, Parallel, and Fiber-Optic QSFP+ Transceiver for 40 Gigabit Ethernet Applications. This transceiver is a high performance module for short-range multi-lane data communication and interconnects applications.

 

It integrates four data lanes in each direction with 40 Gbps bandwidth. Each lane can operate at 10.3125 Gbps up to 100 m using OM3 fiber or 150 m using OM4 fiber. These modules are designed to operate over multimode fiber systems using a nominal wavelength of 850nm. The electrical interface uses a 38 contact edge type connector.

 

The optical interface uses a 12 fiber MTP (MPO) connector. This module incorporates Technologies proven circuit and VCSEL technology to provide reliable long life, high performance, and consistent service.

 

Q&A

-----------------------------------------------------------------------------------------------------------

Q: How many types of the fiber optic transceiver?

 

A: According to the optical module function, fiber optic transceivers can be divided into fiber optical receiver module, fiber optical transmission module, fiber optical transceiver module and fiber optical transponder module.

 

 

Q: What is the main function of fiber optic transceivers?

 

A: Fiber optic transceiver module main function is to achieve the conversion between optical-electrical and electrical-optical, including optical power control, modulation transmission, signal detection, IV conversion and limiting amplifier decision regeneration, in addition, there are security information query, TX-disable and other functions.
