Fan Tray Assembly
Releases 1.0.x of the ONS 15327 included a fan tray with two fans. Release 3.3 introduces a fan tray
unit that uses six fans, and is I-temp certified. The new fan tray is backward compatible will any existing
ONS 15327 chassis. The fan tray assembly consists of six fans, a status LED on the faceplate, and a fan
control PCB.
Wall Mounted Enclosure
The Release 3.3 ONS 15327 hardware can be mounted in a wall mount enclosure. The enclosure contains
the ONS 15327 chassis, a rectifier, and battery backup. The rectifier can be plugged into a 110 VAC wall
socket to power everything in the enclosure.
OC3/STM1-IR-4 (1310)
The OC3/STM1-IR-4 provides four Telcordia GR-253 SONET/SDH compliant interfaces per card. Each
interface operates at 155.52 Mbps over a single mode fiber span and may be provisioned for both
concatenated and non-concatenated payloads on an STS-1 basis.
The OC3/STM1-IR-4 has 4 standard GR-253/G.957 compliant OC3/STM-1 interfaces running TCP/IP
over the Section DCCs enabling it to interoperate with a Cisco ONS 15327 OC3/STM-1 interface or a
Cisco ONS 15303/15304 OC3/STM-1 interface for all transport applications. The OC3/STM1-IR-4 card
may be installed in any high-speed slot in the shelf assembly.
Each interface features a 1310 nm laser to support spans without repeaters at distances up to
approximately 15 kilometers depending on the condition of facilities. Each interface contains a
transmitter and receiver. The OC3/STM1-IR-4 is only available with LC connectors.
Each OC3/STM-1 port on the OC3/STM1-IR-4 can participate in a 1+1 Line Switched protection
scheme, STS-1/VT1.5 Path Switched protection scheme (UPSR), or Cisco's Path Protected Mesh
Networks (PP-MN). BLSR protection is not supported on the OC3/STM1-IR-4 card.
OC12/STM4-LR-1 (1550)
The OC12/STM4-LR-1550 Long Reach optical transceiver module provides one Telcordia
GR-253/G.957 SONET/SDH OC12/STM-4 compliant interface per card. Each interface provides 622.08
Mbps over a single mode fiber span and may be provisioned for both concatenated and non-concatenated
services on an STS-1 basis.
The OC12/STM4-LR-1550 card can be installed in any of the high-speed slots in the Cisco ONS 15327
shelf assembly. Each interface features a 1550nm laser to support spans with no repeaters at distances
of approximately 80 kilometers, depending on the condition of the facilities. Each interface contains a
transmitter and receiver using SC optical connections.
The OC12/STM4-LR-1550 supports 1+1 Line Switched, BLSR, Path Switched protection scheme
(UPSR), or Cisco's Path Protected Mesh Network (PPMN). The OC12/STM4-LR-1550 has a standard
GR-253/G.957 compliant OC12/STM-4 interface running TCP/IP protocol over the section DCCs,
enabling it to interoperate with a Cisco ONS 15454 OC12/STM-4 interface for all transport applications.
