Description

Overview
The Cisco SFP ONS OC3/STM-1 Module (part number 10-1957-01) is a compact, hot-pluggable optical transceiver designed for high-performance carrier Ethernet and SONET/SDH networks. It delivers reliable OC3 (155 Mb/s) or STM-1 (155 Mb/s) transmission over multimode fiber, enabling service providers and enterprises to extend bandwidth without sacrificing space or power efficiency.

Key Features

Supports both OC3 and STM-1 data rates at 155 Mb/s
Hot-swappable design for zero-downtime upgrades and maintenance
Low power consumption helps reduce overall system energy costs
Built-in diagnostic monitoring (DOM) provides real-time optical performance data
Compatible with a wide range of Cisco ONS platforms and chassis

Technical Specifications

Form factor: SFP (Small Form Factor Pluggable)
Wavelength: 850 nm
Fiber type: Multimode fiber (MMF) up to 2 km at standard loss budget
Connector type: LC duplex
Operating temperature: 0 deg C to 55 deg C (industrial range)
Power consumption: max 1.5 W per module
Compliance: ITU-G.983, IEEE 802.3z

Applications
The SFP ONS OC3/STM-1 Module is ideal for metro Ethernet aggregation, backhaul links, and carrier grade transport networks. It is commonly deployed in:

Metro access nodes connecting to regional hubs
Enterprise data center interconnects requiring high reliability
Service provider edge routers and switches for rapid service provisioning
Optical distribution frames where space constraints demand small form factor transceivers

By integrating this Cisco SFP module, customers gain a flexible, future-proof solution that simplifies network upgrades while maintaining the high performance expected from carrier-grade equipment.
