Definition:

The compact small form-factor pluggable (CSFP) is a version of SFP with the same mechanical form factor allowing two independent bidirectional channels per port.

CSFP vs SFP

Compact small form-factor pluggable CSFP transceiver and a compact small form-factor CSFP transceiver supports network systems, especially those deploying single-fiber bidirectional transceivers in high-density applications. The CSFP MSA defines a transceiver mechanical form-factor with latching mechanism and a host board, SFP-like, electrical edge connector and cage. The CSFP MSA also defines a transceiver mechanical form-factor. The dual-channel CSFP has the same mechanical dimensions as the industry-standard SFP transceiver and is compatible with the standard SFP cage. The single-channel CSFP and CSFF are half the size of the industry-standard SFP and SFF packages. The CSFP design is modular to enable configurations of integrated 2ch modules. In future Eotpolink will develop 4ch CSFP modules. These highly integrated compact transceiver modules will enable network system vendors to increase port density and data throughput while reducing network equipment cost.

What is the difference between SFP, BiDi SFP, and CSFP fiber optic transceiver?

Normal SFP module is dual-fiber transceiver which has two LC connectors. Two connectors respectively indicated TX and RX. The bidirectional sfp transceiver is single fiber transceiver which could be one LC or SC connector. The CSFP is a dual bidirectional SFP type that has the same form factor as a regular SFP, but can support 2 users that use BX type of optics.

Conclusion

CSFP concluded attribute integration involving a pair of classic single-fiber bidirectional SFP modules. The CSFP composition is made up of a pair of unbiased lighting emitting along with acquiring routes. Throughout every single station, you will find there's PLC BOSA unit is liable for optical indication acquiring plus the power indication is a key portion of CSFP module. The key differences make the modules work efficiently in their respective applications.
