SFP-ETRx-4

10/100/1000 BASE-T Copper SFP Transceiver

SFP-ETRx-4

OPT-ETRx-4 Copper Small Form Pluggable (SFP) transceivers are based on the SFP Multi Source Agreement (MSA). They are compatible with the Gigabit Ethernet standards as specified in IEEE STD 802.3. The 10/100/1000 BASE-T physical layer IC (PHY) can be accessed via 12C, allowing access to all PHY settings and features.

The OPT-ETRx-4 is compatible with 1000BASE-X auto-negotiation, and have a link indication feature. PHY is disabled when TX disable is high or open.

LC Type

Fiber optic adapter, sometimes also called a coupler, is a small device designed to terminate or link fiber optic cables or fiber optic connectors between two fiber optic lines. It contains the interconnect sleeve that holds two ferrules together. By precisely linking two connectors, fiber optic adapters allow the light sources to be transmitted at their maximum and minimize the loss as much as possible. At the same time, fiber optic adapters have the advantages of low insertion loss, good interchangeability, and reproducibility. They are used to connect optical fiber connectors such as FC, SC, LC, ST, MU, MTRJ, D4, DIN, MPO, etc. They are widely used in optical fiber communications equipment, measuring appliances, and so on. The performance is stable and reliable.
