Cisco SFP-10G-ER-S 10GBASE-ER 1550nm SMF Transceiver Modules

SFP-10G-ER-S is a small form-factor pluggable (SFP+) optical module commonly used in 10G Ethernet. The following is a detailed introduction to its technical parameters:

Basic Information

Standard Compliance: Complies with IEEE 802.3ae 10GBASE-ER Ethernet standard and SFP+ MSA (Multi-Source Agreement), ensuring good compatibility with other network devices that support this standard.

Transmission rate: Supports data transmission rates up to 10.3125Gbps, which can meet the needs of high-speed network communication.

Optical characteristics

Wavelength: A 1550nm distributed feedback (DFB) laser is used as the transmitting light source. This wavelength has low loss in single-mode fiber transmission.

Transmission distance: On single-mode fiber (SMF, G.652), the maximum transmission distance can reach 40km, which is suitable for medium and long-distance network connections.

Transmitted optical power: The typical transmitted optical power range is between -3dBm and +3dBm, which can ensure that the optical signal is effectively transmitted within the specified distance.

Receiving sensitivity: The minimum receiving sensitivity is about -19.5dBm, which can reliably detect weak optical signals.

Overload optical power: Generally -3dBm, that is, when the receiving optical power is higher than this value, it may affect the receiving performance.
