Use Fiber Optic Transceiver Precautions!

There are many different classifications of fiber optic transceivers, and in practice most of the attention is divided into categories based on different fiber connectors: SC connector fiber transceivers and FC/ST connector fiber transceivers.

When using fiber optic transceivers to connect different devices, care must be taken to use different ports.

1. Connection of fiber transceivers to 100BASE-TX devices (switches, hubs):

Make sure the length of twisted pair does not exceed 100 meters.

Connect one end of the twisted pair cable to the RJ-45 port (Uplink port) of the fiber transceiver and the other end to the RJ-45 port (common port) of the 100BASE-TX unit (switch, hub).

2. Connection of fiber transceivers to 100BASE-TX devices (network cards):

Make sure the length of twisted pair does not exceed 100 meters.

Connect one end of the twisted pair cable to the RJ-45 port (100BASE-TX port) of the fiber transceiver and the other end to the RJ-45 port of the network card.

3, fiber optic transceiver to 100BASE-FX connection:

Make sure that the length of the fiber does not exceed the distance that the device can provide;

One end of the fiber is connected to the SC/FC/ST connector of the fiber transceiver and the other end is connected to the SC/ST connector of the 100BASE-FX device.

It is also necessary to add that many users consider using fiber optic transceivers as long as the length of the fiber can be used within the maximum distance supported by single mode fiber or multimode fiber. In fact, this is a wrong understanding. This understanding is only correct when the connected devices are full-duplex devices. When there are half-duplex devices, the transmission distance of the optical fiber is limited.

Peristaltic Liquid Pump

Peristaltic Liquid Pump is a Peristaltic Pump that can distribute many types of liquids, such as water-based liquid/shampoo/sauce/chemical-based liquid, etc.
The flow rate of the Peristaltic Liquid Pump can be adjusted by the digital knob to adjust the motor speed to achieve the effect of adjusting the flow rate
The liquid only gets in touch with the Peristaltic Pump Tubing, will not cause cross-contamination. it's suitable for Liquid transfer occasions with high cleanliness requirements, Eg. : food/beverage/cosmetic/medical/biopharmaceutical...
For the Peristaltic Pump Tubing, We have different material choices for your various liquids. The standard tube is silicon tubing which conforms to the FDA certificate. Except that we also offer the Saint-Gobain imported tubing, Eg.: Norprene®A-60-F/Norprene®chemical /Pharmed® BPT... Which suitable for various chemical-based liquids
