Description
ESFP-GE-SX-MM850 is a gigabit multimode optical module designed specifically for short distance, high-speed data transmission. It uses 850nm wavelength and duplex LC interface, usually used for interconnection between devices inside the computer room or within the same building
Short distance and high speed: 850nm vertical cavity surface emitting laser (VCSEL), compatible with multimode fiber, capable of stable gigabit transmission within 550 meters.
Flexible Reuse: The eSFP package is compatible with SFP slots and can be interchanged with modules such as SFP-GE-LX-SM1310.
High reliability: Industrial grade temperature range, MTBF of about 1 million hours, suitable for dense deployment in computer rooms.
Easy operation and maintenance: Supports DDM real-time monitoring of optical power and rapid fault location.
