The Optical Ethernet Transponder (OEX) provides the ability to manage fiber nodes and optical hubs through an existing fiber optic infrastructure. Contact an Alpha Technologies representative for a complete listing of supported fiber nodes. The transponder leverages the operator’s fiber optic network infrastructure and communicates with a management system, using standard Simple Network Management Protocol (SNMP).
1.0 Introduction, continued 1.2 Optical Module The OEX uses an industry-standard SFP (Small Form-factor Pluggable) optical transceiver, to provide great flexibility in optical connection options. Any SFP module rated for at least 1Gb/s (gigabit) data rate will work in the OEX. (However, SFP+ modules (typically rated for 10Gb/s or faster) are not compatible with the OEX.) If the OEX is using a dedicated fiber pair just for its communications, a standard data SFP may be chosen.

2.0 Connections 2.1 Overview The OEX communicates with the fiber optic network through the SFP (Small Form-factor Pluggable) transceiver module. The OEX includes two status LEDs, a local Ethernet port (a standard RJ-45 Ethernet connector), an optical tamper sensor, and a node interface connector. The transponder receives its power and performs communications with the node all via the node interface connector.
2.0 Connections, continued Slot Interface Connector Fig. 2-2, OEX Connections 2.2 Connector Summary Connector Summary Connector Description The SFP module is installed into the slot. The SFP must be oriented as indicated on the top of SFP Slot the transponder. The Ethernet port is a local interface into the OEX when the SFP is not connected, or a local interface into the optical network when the SFP is connected.
3.0 Installation Network infrastructures each have unique characteristics; therefore, Alpha Technologies strongly recommends completely installing one transponder and making it operational before deploying the entire system throughout the network. Installing the transponders and making them operational consists of the following steps, which are explained in detail in this section.
3.0 Installation, continued OEX Provisioning Process Action Result • Prior to attaching the Fiber to SFP connectors, user has ability to Install OEX in target device connect to OEX through local Ethernet port using 192.168.100.1 IP address • OEX contacts the DHCP server Connect fiber to SFP Connector •...
3.0 Installation, continued The DHCP Server The address for the OEX can be offered up by any DHCP server (following RFC 2131). The details of managing any particular DHCP server vary, but there are two basic areas of interest: setting up a specific DHCP offer for a particular device, and providing the options within the DHCP offer to support the time of day and configuration file operations.
3.0 Installation, continued 3.2 The Configuration File The security of the OEX and its control of the fiber node depends upon the configuration file settings. Verify that the transponder configuration file has been successfully tested prior to deploying transponders into the network in quantity. The OEX manages SNMP remote access and notification/trap destinations according to its internal configuration settings.
3.3 Installing the OEX This section provides the steps for installing the OEX into a GS7000 optical hub or node. Remove the OEX from the shipping package. Do not install the SFP yet. Position the transponder so the interface connector shown in Fig. 3-3 aligns with the node’s interface connector shown in Fig.
3.0 Installation, continued Fig. 3-4, Transponder Slot and Interface Connector Firmly push the OEX down onto the node’s mother board until the transponder seats into position. Use the captive screws in the transponder to secure it to the mother board. The screw locations are shown in Fig. 3-5. CAUTION! Exercise caution when installing the OEX to assure proper alignment between the connectors to avoid damaging the pins.
3.0 Installation, continued Install the SFP into the slot in the OEX, oriented as indicated on the top of the enclosure. Slide the SFP into place so that it seats firmly. Fig. 3-6, SFP in Place Install the fiber(s) into the SFP. Route the fiber(s) neatly to the fiber management tray to avoid loose cabling inside the node.
3.0 Installation, continued 3.4 Checking the LEDs The OEX has two green LEDs for indicating operational status.

The files in Table 4-1 can be found on the Society of Cable Telecommunications (SCTE) Web site, www.scte.org. The files in Table 4-2 and Table 4-3 are provided by Alpha Technologies or Cisco. There are dependencies between MIB files, so compile them in the order shown in the following tables.
4.0 Provisioning the SNMP Manager, continued NOTICE: In the OEX, hfcnReturnLaserOpticalPower (OID 1.3.6.1.4.1.926.1.5.4.3.1.11) and hfcnOpticalReceiverOpticalPower (OID 1.3.6.1.4.1.926.1.5.4.4.1.5) have a higher resolution (.001 milliWatts) than the fnReturnLaserOpticalPower and fnOpticalReceiverPower. These new components are located in ATI-DEV-HFC-NODES-MIB. The fnReturnLaserOpticalPower and fnOpticalReceiverPower components are still supported, but have a lower resolution.
5.0 Network Interfaces The OEX possesses two network interfaces (Fig. 5-1). The optical link, through the SFP slot, is the primary communications link back to the network and any management systems. There is also an Ethernet port on the OEX, for local access by an installer or a technician.
5.0 Network Interfaces, continued Fig. 5-1, Network Interfaces The local port may also support SNMP access; however, SNMP access is still subject to the same access rights whether the OEX is using the optical network link or local link. So, it’s up to the configuration of the OEX (including access setup from the configuration file described in section 3) whether local SNMP access is possible.
