SFP Transceiver Product Selector

Choose from different models for the required speed, distance and connection.

An SFP, or Small Form-factor Pluggable, is a compact transceiver used to provide cost-effective, instant fibre (or copper) connectivity to network devices, from Ethernet switches to routers, firewalls and NIC cards. Which SFP transceiver you choose depends on the application, cable type, required range for the network and the desired data transmission rate.

Black Box offers a full range of SFP, SFP+ and QSFP28 transceivers, all of which feature extended diagnostics. Our optical transceivers are designed for use with Emerald™ IP switches, industrial Ethernet switches, media converters and console servers, and most 3rd party equipment that supports SFP transceivers.

Notes

(1) Compatible with devices with a SerDes cage that support 1000 Mbps.
(2) Compatible with devices with a SGMII interface that support 10/100/1000 Mbps.
(3) The WDM (or Wavelength-Division Multiplexing) technique enables the use of multiple light wavelengths to send data over the same medium. In this case: 1295.56, 1300.05, 1304.58 and 1309.14 nm.

Extended diagnostics

Besides basic link characteristics such as SFP type, length of fiber link, wavelength and bit rate, all Black Box SFP transceivers feature extended diagnostics. This enables SFP transceivers to report information such as temperature, TX and RX power, voltage and bias current.

Hot-swappable vs. hot-pluggable

On our SFP transceiver product pages you will find words like hot-swappable and hot-pluggable while reading the specifications. Why does an SFP transceiver have such a specification?

Hot-swappable means that the SFP transceiver can be removed and replaced by another transceiver without shutting down the system or without significant system downtime. If a new SFP transceiver can be added but cannot be removed without some kind of interference, we call it hot-pluggable.
