Description

Luminex LU 90 00871 – 1.25GBD SFP Multi-Mode Fiber Transceiver (for GigaCore Systems)

Fiber Compatibility

This hot-pluggable transceiver is capable of transmission at 2 to 550 meters with 50/125 nm fiber, and at 2 to 275 meters with 62.5 125 nm fiber, for 1.25 GBd Ethernet. It is capable of transmission up to 500m with 50/125 ?m fiber and up to 300m with 62.5/125 nm fiber, for 1.0625 GBd Fiber Channel.

Operating temperature from -40 to 85¡ C

Recommended Operating Conditions are those within which functional performance within data sheet characteristics is intended. This SFP Transceiver can operate in temperatures between -40 and 85¡ C.

Compliant to IEEE 802.3 Gigabit Ethernet (1.25GBd) 1000BaseSX

The MMF Transceivers are compliant with the specifications set forth in the IEEE802.3 (1000Base-SX) and the Small Form-Factor Pluggable (SFP) Multi-Source Agreement (MSA). Its primary application is servicing Gigabit Ethernet links between optical networking equipment like f.e. the GigaCore 16Xt or 26i.

Eye safety certified

The transceiver provides Class 1 eye safety by design. The eye safety circuit continuously monitors optical output power levels and will disable the transmitter and assert a TX1/2FAULT signal upon detecting an unsafe condition. Such unsafe conditions can be created by inputs from the host board (Vcc fluxuation, unbalanced code) or faults within the module.

Diagnostic Monitoring

The DDM function provides component monitoring on transceiver applications in details. A DDM interface can include a system of alarm and warning flags which alert the host system when particular operating parameters for transmitted power, received power, laser bias current, temperature or supply voltage are outside of a factory set normal operating.

850 nm Vertical Cavity Surface Emitting Laser (VCSEL)

The VCSEL is a type of semiconductor laser diode with laser beam emission perpendicular from the top surface, contrary to conventional edge-emitting semiconductor lasers (also in-plane lasers) which emit from surfaces formed by cleaving the individual chip out of a wafer.
