## Summary description

The BlueOptics JSH-21S3AB3-BO is a fiber optic SFP transceiver module with a maximum transfer distance of 550 m. It features an aluminum body and weighs 20 g. Ideal for high-speed data transmission in networking applications.

## Long description

The BlueOptics JSH-21S3AB3-BO is a single‑port SFP fiber optic transceiver module designed for short‑range multimode fiber links with a maximum transfer distance of 550 m. The module supports 1000Base‑SX data rates and uses an LC duplex connector. Its aluminium housing and compact SFP form factor allow installation in switches, routers and other networking equipment that accept MSA‑compliant SFP modules.
Advantages
This SFP transceiver provides gigabit optical connectivity over multimode fiber with an industry‑standard LC duplex interface and an aluminium enclosure that keeps the module lightweight (approx. 20 g). It is built to MSA specifications for form factor and electrical/optical compatibility and includes transmitter and receiver sections operating at 850 nm to support common short‑reach applications. The compact SFP format and standardized interface simplify replacement and upgrades in compatible network hardware.
Suitable for
 Short‑reach gigabit Ethernet links over multimode fiber (up to 550 m)
 Connections between switches, routers and patch panels within data centers and enterprise networks
 Storage and server interconnects requiring 1 Gbps optical links
 Environments where EMI immunity and optical isolation are required
Key specifications
 Interface type: SFP (MSA compliant)
 Supported standard: 1000Base‑SX (1.25 Gbps)
 Wavelength: 850 nm (transmit and receive)
 Maximum range: up to 550 m over multimode fiber
 Connector: LC duplex
 Housing material and colour: aluminium / aluminium finish
 Weight: approximately 0.02 kg
How to use
Insert the SFP transceiver into a compatible SFP slot of your network device until it latches. Connect LC duplex multimode fiber patch cords to the module, observing transmit (Tx) and receive (Rx) orientation. Verify that the host equipment supports 1000Base‑SX SFP transceivers and, if available, enable or verify Digital Diagnostics Monitoring (DDM/DOM) support in the device to access real‑time module parameters. After connection, check link LEDs and device diagnostics to confirm a stable optical link.
Usage recommendations
For optimal performance, use multimode fiber and LC duplex patch cords rated for 850 nm, ensure clean connector endfaces before mating, and follow the host device vendor guidance on supported third‑party SFP modules. If remote monitoring is required, confirm the host supports DDM/DOM to read supply voltage, temperature, laser bias, and optical power values.
