CWDM SFP (40 km) specifications
Item
Specification
Physical dimensions
0.457 X .604 X 2.18 inches
(11.6 X 15.3 X 55.43 mm)
Connectors
Duplex LC fiber optic
Cabling
SMF, 9 µm
Average launch power
minimum: -4 dBm
maximum: +1 dBm
Data rate
Nominal range: 1.0625 to 1250 Mbaud
Optical budget
17 dBm
Operating temperature range
0oC to 60oC
Regulatory
Class 1 devices per FDA/CDRH and IEC60825-1
Laser Safety Regulations
Receiver Characteristics
Minimum receiver sensitivity
-21 dBm
Maximum input power
-3 dBm
Note:
A minimum attenuation of 5 dBm must be present between the
transmitter and receiver. To avoid receiver saturation, you must insert a
minimum attenuation of 5 dBm when:
•
testing the CWDM SFP in loopback mode.
•
using short runs of fiber with no intermediate CWDM OADM or
CWDM OMUX.
To determine the expected signal loss for a CWDM OADM, CWDM
OMUX, or fiber length, see
Installation and Networking Guidelines for
Optical Routing
.
Given a loss budget of 24 dBm and assuming fiber loss of .25 dB/km, up
to 96 km reach is supported with no intermediate CWDM OADM or
CWDM OMUX.
