• Manufacturer Part Number: HFBR-53A3VEM
• Description: 3.3 V 1 x 9 Fiber Optic Transceivers for Fibre Channel for Fibre Channel
• Manufacturer: HP [Agilent(Hewlett-Packard)]

Notes:
1. Optical Extinction Ratio is defined as the ratio of the average optical power of the transmitter in the high (“1”) state to the low (“0”) state.
2. These are 20-80% values and include the effect of a fourth order filter.
3. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 1). The characteristics include rise time, fall time, pulse
4. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
5. Return loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.
