1. 10 Gigabit Small Form Factor Pluggable (XFP) is a heat-exchangeable, protocol-independent optical transceiver for 10 gigabytes of bps Ethernet, SONET/SDH, and Fibre Channel.
2. Small pluggable transceiver (SFP), the most widely used at present.
3.GigacBiDi series single-fiber bidirectional optical modules use the WDM technology to transmit bidirectional information signals (point-to-point transmission) by one optical fiber. In particular, optical fiber resources are insufficient, and one optical fiber is required to transmit bidirectional signals.) GigacBiDi includes SFP single-fiber bidirectional (BiDi), GBIC single-fiber bidirectional (BiDi), SFP+ single-fiber bidirectional (BiDi), XFP single-fiber bidirectional (BiDi), SFF single-fiber bidirectional (BiDi) and so on.
4.RJ45 Electrical port Small pluggable module, also called electrical module or electrical port module.
5.SFF is divided into 2x5, 2x10 and so on according to its pins
6. Gigabit Ethernet interface converter (GBIC) module
7. PON(A-PON, G-PON, GE-PON) optical module of the passive optical network
8.40Gbs high-speed optical module
9.SDH transmission module (OC3, OC12, OC48)
10. Storage module, such as 4G, 8G, etc.
25G SFP28 DAC is a 25GBASE-CR direct attach copper cable for data center environment. It provides a high speed, cost-effective alternatives to fiber optics in 25GbE Ethernet applications.
fiber pigtail is typically a fiber optic cable with one end factory pre-terminated fiber connector and the other exposed fiber.
This Article just briefly overviews 10G and 25G Ethernet (25Gb) technologies, focusing on the SFP+ transceiver and SFP28 transceiver.
