Sklenené vlákno transceiver modul BlueOptics JSH-42L3DD1-BO 1250 Mbit/s LC

The BlueOptics JSH-42L3DD1-BO is a single‑mode fiber optic SFP transceiver module designed for 1.25 Gbit/s (1250 Mbit/s) applications. It uses an LC duplex interface, is compact and lightweight (approximately 20 g), and complies with CE, RoHS and FCC standards. The module implements a 1000BASE-LX optical link profile suitable for long-reach single‑mode fiber connections and supports simultaneous transmit and receive operation via separate fibers.

Advantages

This BlueOptics transceiver offers protocol flexibility for Ethernet and related high‑speed optical applications up to 1.25 Gbit/s while following MSA physical form‑factor standards for SFP modules. Its LC duplex connector and single‑mode optical design provide EMI‑immune transmission over extended distances. The module's small size and low weight simplify installation in switches, routers and storage systems, and compliance with CE, RoHS and FCC indicates adherence to common regulatory and environmental requirements.

Key specifications

How to use

Install the BlueOptics SFP transceiver into an SFP port on compatible network hardware until it latches; connect LC duplex single‑mode patch cords to the module’s transmit and receive fibers, observing proper polarity. Ensure the host device supports 1000BASE‑LX SFP modules and that any required software or firmware settings permit the transceiver. After connection, verify link status on the host device and confirm optical power and link negotiation. Handle the module by its housing, avoid touching the optical interfaces, and keep dust caps on until final connection.

Recommendations

For optimal performance, pair the transceiver with single‑mode fiber and high‑quality LC connectors, verify compatibility with the target switch or router, and follow workplace ESD precautions when inserting or removing the module. If digital diagnostics (DDM/DOM) are required, ensure the host supports that feature to monitor transmit/receive power and module temperature in real time.
