SM = SingleMode Fiber 8.6 to 9.5 mm mode field diameter as per ITU-T G.652.

* Specifications subject to change and some supplier variation. Also, consult the relevant reference for details on measurement assumptions/methodology.

** Stressed eye sensitivity values in OMA are shown (sensitivity values shown in brackets are approximate and by IEEE definition for informative use only - consult IEEE link budget planning documentation/model for further details)

*** Maximum transmission distance is dependent upon multimode fiber type used as per IEEE 802.3ae Table 52-6 shown below.

(4) Longer distances attainable thru engineered links using dispersion compensation and optical amplification. Optical output power adjust feature can lower optical output power below minimum stated level if required by DWDM engineered link design.

(5) 100GBASE multi-lane optical Tx/Rx power levels stated are per lane based OMA values.

(6) 40GBASE multi-lane optical Tx/Rx power levels stated are per lane based OMA values.

****For optically amplified networks, the spec for 3HE04999CA is:
Fiber dispersion must be between -400ps/nm and +1600ps/nm, the Rx power must be between -7dBm and -19dBm and the net OSNR >27dB to guarantee BER 10^-12 performance.

We keep track of the maximum dispersion limited distance and penalty. What ever the stated reach of a part is (i.e. 10km, 40km, 80,km etc) that is the maximum chromatic dispersion limited transmission "distance" that a customer could use (provided fiber loss is low enough to meet the link budget). The chromatic dispersion "penalty" (in dB) is found in the "optical path penalty" column of the optics reference chart. If they want to know the dispersion value for 1550nm optics, multiply the rated distance x 20ps/nm/km. For 80km for example it's 80km x 20ps/nm/km = 1600ps/nm. dispersion value for 1550nm optics, multiply the rated distance x 20ps/nm/km. For 80km for example it's 80km x 20ps/nm/km = 1600ps/nm.

10GBASE-S Operating Range for Optical Fiber Type

	Minimum Modal
	Bandwidth	Operating
Fiber Type	(MHz*km)	Range (m)
62.5 mm MMF	160	2 to 26
62.5 mm MMF	200	2 to 33
50 mm MMF	400	2 to 66
50 mm MMF	500	2 to 82
50 mm MMF	2000	2 to 300

For the 10GBASE-L 802.3ae IEEE document details two specifications:

1) OMA stressed eye sensitivity = -10.3dBm (degraded optical fiber link conditions as per IEEE stressed eye test to simulate that)

2) Unstressed eye sensitivity = -14.4dBm. (Back to back, 0km of fiber, undegraded optical fiber conditions or penalties)

The customer can determine which value is relevant to their system application dependent upon how they prefer to do their link budgets.

The 802.3ae IEEE document discusses this (see Table 52-6 in the IEEE 802.3ae).

For the 10GBASE-E 802.3ae IEEE document details two specifications:

1) OMA stressed eye sensitivity = -11.3dBm (degraded optical fiber link conditions as per IEEE stressed eye test to simulate that)

2) Unstressed eye sensitivity = -15.8dBm. (Back to back, 0km of fiber, undegraded optical fiber conditions or penalties)

The customer can determine which value is relevant to their system application dependent upon how they prefer to do their link budgets.
