## Summary description

The BlueOptics BOLBLCOM4 is a fibre optic adapter with LC connectors available in black and pink. It is compliant with RoHS standards and designed for high-speed data transmission in OM4 category networks.

## Long description

The BlueOptics BOLBLCOM4 is a fibre optic loopback adapter with LC duplex connectors, intended for multimode OM4 (50/125 µm) networks operating around 850 nm. Designed for test, inspection and isolation of transmission faults, this adapter provides a reliable return signal for transmit/receive ports and supports high-speed data transmission. The unit is available in a black and pink housing and uses a zirconia ceramic ferrule to ensure stable optical alignment and long-term durability.
Advantages
The adapter offers low insertion loss and high return loss suitable for OM4 multimode links, with components assembled from recognized manufacturers to maintain consistent performance. It is factory-tested using interferometry and OTDR to verify optical parameters and meets Telcordia GR-326-Core 4.4 requirements. The construction includes a flame-retardant LSZH jacket to reduce smoke and avoid halogen emissions in case of fire, and it is rated for operation in a broad temperature range from -40°C to +75°C.
Suitable for
 Functional testing of fibre transceivers and SFP/SFP+ modules
 Burn-in and laboratory test setups for multimode OM4 links
 Troubleshooting and loopback verification in data center and enterprise networks
 Quality control and maintenance procedures for fibre optic installations
Key specifications
 Connector type: LC duplex
 Fiber category: Multimode OM4 (50/125 µm)
 Wavelength: optimized around 850 nm
 Ferrule material: zirconia ceramic
 Temperature range: -40°C to +75°C
 Jacket material: LSZH (low smoke, zero halogen)

 Manufacturing tests: interferometer and OTDR verified
How to use
To use the BlueOptics BOLBLCOM4 loopback adapter, insert the LC duplex connector into the device's optical port that requires a return signal or needs loopback testing. Ensure connectors and ports are clean and free from dust before mating. The adapter will reflect the transmit signal back to the receiver, allowing verification of link behaviour, diagnostics or burn-in procedures. Remove the adapter after testing and store it in a protective cap or case to avoid contamination of the ferrule.
Usage recommendations
Prior to connection, clean both the adapter connector and the equipment port with appropriate fibre cleaning tools to maintain low insertion loss. Use the adapter only with OM4 multimode equipment and avoid excessive bending of connected fibres. For repeat testing, inspect connectors regularly and replace the adapter if physical damage or a persistent rise in loss is observed.
