OPTIC DESCRIPTION

QTY 1  ORIGINAL CIENA p/n XCVR-S40U27

The XCVR-S40U27 is a high-performance, bidirectional (BiDi) SFP+ optical transceiver module designed for high-speed telecom, data center, and enterprise network applications. It provides an aggregate 10 Gbps Ethernet throughput over distances up to 40 kilometers using a single strand of Single-Mode Fiber (SMF) 


Are you looking to purchase replacement units?
 let us know SEND US A MESSAGE:

Are you looking for a pricing and availability quote, datasheet specifications (like transmission distance/link budget), or checking its compatibility with a specific Ciena platform (like the 6500 or 3900 series)

Compatibility & Network Architecture
  • Because BiDi modules operate by transmitting and receiving data on different wavelengths over the exact same single fiber strand, this unit must be paired with a complementing transceiver on the opposite end of the optical link. The standard matching counterpart is the XCVR-S40U33, which flips the optics to utilize a 1330nm-TX / 1270nm-RX configuration. [1]
    Depending on your deployment environment, it is available in standard commercial operating temperatures (0°C to 70°C) as well as ruggedized industrial temperature variations (-40°C to 85°C). [1, 2, 3]
    Are you trying to resolve a compatibility issue, source a replacement module, or find its matching downstream counterpart (XCVR-S40U33)? Let me know your hardware configuration so I can assist further.Do you need current hardware and other optics?
  • or do you need to know if it fits a specific line card model inside a Ciena platform?  
1. Native Ciena Devices
If you are using an official Ciena module or a direct "Ciena-coded" equivalent, it is explicitly built to be accepted in the 10G SFP+ ports of the following platforms: [1]
  • Service Delivery Switches (SDS): Ciena 3926, 3928, and 3930.
  • Service Aggregation Switches / Platforms: Ciena 5160 and Ciena 5170.
  • Carrier Ethernet Portfolios: Various line cards within the Ciena 6500 Packet-Optical Platform and 8700 Packetwave series supporting 10G interfaces. [1]

Do you need to verify switch hardware compatibility for a specific deployment, or find troubleshooting steps for a deployed module?
Are you looking because you are migrating to a non-Ciena environment?  
2. Multi-Vendor Compatibility (Third-Party Coding)
Because the XCVR-S40U27 standard is structurally compliant with the global SFP+ Multi-Source Agreement (MSA), the physical module can function in almost any standard 10G network device. Optics manufacturers (like FS.com or AddOn) routinely flash custom firmware onto this model so it bypasses vendor lock-ins. [1, 2, 3, 4]
When properly coded, the module works seamlessly with: [1]
  • Cisco: Catalyst series (e.g., 3850, 9300), Nexus data center switches (e.g., 3000, 9000), and ASR routers.
  • Juniper: EX/QFX switches and MX series routers.
  • Arista: 7050 and 7060 series data center switches.

Core Specifications:
  • Form Factor: SFP+
  • Data Rate: 1.25 Gbps to 10.3125 Gbps (optimized for 10GBASE-BX40 Ethernet)
  • Wavelength Configuration: 1270nm-TX (Transmit) / 1330nm-RX (Receive)
  • Connector Type: Simplex LC connector
  • Maximum Link Distance: 40 km (approx. 24.9 miles)
  • Optical Budget: 16 dB with a receiver sensitivity of less than -15 dBm
  • Power Consumption: Ultra-low efficiency, pulling between 1.0W and 1.5W maximum
  • Monitoring Features: Digital Diagnostics Monitoring (DDM) / Digital Optical Monitoring (DOM) compliant via the SFF-8472 protocol for real-time monitoring of voltage, temperature, and optical power.
