Ethernet Optical Port
On the H20RN
-
2000.V2 series platforms, GE08/GE08G/GU08 provides 8 GE optical ports;
XGE02/XGE02G/TU02 provides 2 10GE optical ports. There is a 10GE port on the rear panel of
slot7. GE optical ports use LC dual
-
fiber SFP optical module and single
-
fiber SFP optical
module is also selectable. 10 GE optical ports use LC dual
-
fiber SFP+optical module and
single
-
fiber SFP+optical module is also selectable. When using single
-
fiber transceiver module,
only one optical port exists. The wavelength of single
-
fiber module is its emission wavelength.
When connector is inserted into optical transceiver module socket, the latching tab should be
aligned to the correspondent notch. The bending radius of pigtail fiber should be not less than
50mm. When optical fiber connector is inserted or pulled, do not directly pull the optical fiber.
Please reserve the protection plug on SFP optical module. When no optical fiber is connected,
please ensure that the protection plug is inserted to prevent dust from entering.
Single
-
fiber devices with the same emission wavelength cannot interwork. So when
single
-
fiber devices are interworked, the devices with matched emission wavelengths should
be used.
E1 Port
On the H20RN
-
2000.V2 series platforms, EC16 card supports 16 E1 ports whose impedance
supoort 75Ω and 120Ω. E1 port uses dual
-
E1 socket. Each E1 port is corresponding to
2
-
channel E1. See signal definition in Table 2
