## Summary description

BlueOptics BO28C4334620D-BO is a fiber optic SFP transceiver with a compact cSFP interface supporting up to 1250 Mbit/s. Housed in a metal silver casing, it provides a lightweight (20 g) module for optical network links. Typical uses include connecting switches, routers or media converters in access and metro networks. MTBF 1,000,000 hours.

## Long description

BlueOptics BO28C4334620D-BO is a compact fiber optic SFP transceiver with a cSFP interface designed for single-mode links supporting up to 1250 Mbit/s. The module is housed in a silver metal casing and weighs approximately 20 g. It implements a duplex LC connection and follows MSA-compliant mechanical and electrical specifications for pluggable optical transceivers. Typical applications include connecting switches, routers and media converters in access and metro networks where up to 20 km reach is required. The module offers digital diagnostics monitoring (DDM/DOM) for remote reporting of supply voltage, laser bias current, transmit power, receive power and temperature and has an MTBF of about 1,000,000 hours.
Advantages
The transceiver provides a standardized cSFP form factor and MSA compatibility for straightforward interchangeability with supported hardware. Metal housing in silver ensures robust mechanical protection and moderate thermal dissipation. Support for 1250 Mbit/s data rate and single-mode LC duplex connections enables operation in Ethernet and other high-speed optical protocols over metropolitan distances. Built-in DDM/DOM simplifies link monitoring and troubleshooting by reporting key optical and electrical parameters in real time.
Suitable for
Connecting Ethernet switches and routers in access and metro networks
Linking media converters and optical patch panels
Extending single-mode fiber links up to typical 20 km distances
Replacement or upgrade of MSA-compliant cSFP ports supporting 1.25 G
Key specifications
Interface type: cSFP (MSA-compliant)
Maximum data transfer rate: 1250 Mbit/s (1.25 G)
Fiber type: single-mode fiber (LC duplex connector)
Typical reach: up to 20 km (depending on fiber and link conditions)
Housing: metal, silver color
Weight: approx. 0.02 kg
Diagnostics: Digital Diagnostics Monitoring (DDM/DOM) per SFF-8472
MTBF: approx. 1,000,000 hours
How to use
Insert the BlueOptics cSFP transceiver into a compatible cSFP slot on your switch, router or media converter while the device is powered down or following the host vendor’s hot-plug guidelines. Connect LC duplex single-mode patch cords to the transmit and receive ports, ensuring correct fiber polarity. Verify link status through the host device and, if available, read DDM/DOM parameters to confirm optical power levels and temperature. Observe the host equipment documentation for any required software or compatibility settings.
Usage recommendations
For optimal performance use high-quality single-mode patch cords and clean LC connectors before mating. Ensure the host platform supports 1.25 G cSFP modules and the DDM/DOM function if remote diagnostics are required. Avoid exposing the module to mechanical stress or contamination; store unused transceivers with dust caps in a dry environment.
