Cisco ONS 15216 OSC PTP Filter Module

The Cisco ONS 15216-OSC-PTP Filter module is used in the NCS 2000 network to multiplex and demultiplex the optical signals that are provided by the DWDM SFPs. The module carries the PTP signal at 1510 and 1514 nm and the standard OSC signal at 1518 nm.

The following lists the module's operations:

  • The 1510- and 1518-nm wavelengths are separated from the composite signal entering the COM-W-RX port, and routed toward the PTP-14-W-TX and OSC-W-TX ports respectively.

  • The 1514-nm wavelength is received from the PTP-14-W-RX port, and combined toward the COM-W-RX port.

  • On the other direction, the 1518- and 1510-nm wavelengths are received respectively from the OSC-E-RX and PTP-10-E-RX ports, and combined toward the COM-E-TX port.

  • The 1514-nm wavelength entering the COM-E-TX port is separated, and routed to the PTP-10-E-TX port.

  • The path from OSC-W-RX to COM-W-TX is a simple bypass path (no filtering). The same bypass path applies for the COM-E-RX to OSC-E-TX ports.

Note
The filter propagates the 1510 and 1514-nm signals on the same optical fiber between two adjacent nodes in the opposite direction.

Features

The Cisco ONS 15216-OSC-PTP Filter module has the following features:

  • Thin-film DWDM 100GHz-spaced filters for multiplexing and demultiplexing of optical transmission channels, which are modulated up to 100Gbits.

  • Passive device without active temperature control (Athermal design).

  • Optical connectivity using LC-UPC connectors and 900 micrometer fiber.

  • Integrated tap coupler (PLC or fused fiber).
