76 XFP specifications
Parameter Specifications
Maximum average receive power for
damage 0 dBm
Maximum receiver sensitivity in OMA
(see Note 1) -11.1 dBm
Maximum receiver reflectance -12 dB
Stressed receiver sensitivity in OMA
(see Note 2) -7.5 dBm
Receiver electrical 3 dB upper cutoff
frequency 12.3 gigaHertz (GHz)
Note 1: Receiver sensitivity is informative.
Note 2: Measured with conformance test signal for BER = 10
-12
The stressed sensitivity values are for system level BER measurements,
which include the effects of CDR circuits. Nortel recommends that you
allocate at least 0.4 dB additional margin if you make component level
measurements without the effect of CDR circuits.
10GBASE-LR/LW XFP specifications
The 10GBASE-LX SFP provides 10 GbE service at a nominal wavelength of
1310 nm. This XFP can attain link lengths of up to 10 km.
The following table lists the transmitter specifications for the
10GBASE-LR/LW XFP. The part number of this XFP is AA1403001-E5.
For more information about the 10GBASE-LX XFP, including test and
measurement information, see the IEEE 802.3ae standard.
ATTENTION
You can configure the XFP to operate in either LAN (Ethernet) or WAN (SONET)
mode, depending on the module (8683XLR is a LAN-only module, and 8683XZR
is a LAN/ WAN module). Model numbers ending in R denote a LAN interface;
model numbers ending in W denote a WAN interface.
