Cisco SFP-10G-SR-S Compatible 10G SFP+ SR Optical Transceiver Module | HYTOPTODEVICE

What Is Cisco Compatible SFP-10G-SR-S Optical Transceiver?
SFP+ Transceiver | Cisco Compatible 10GBASE-SR  Optical Transceiver Module(MMF, 850nm, 300m, LC, DOM) | HYTOPTODEVICE
   The 10G-SFP-SR-S is a high-performance, MSA-compliant Cisco-compatible SFP+ optical transceiver. Featuring a hot-pluggable SFP+ form factor, it operates at a fixed 10Gbps line rate over a 850nm wavelength to transmit data, with a transmission distance up to 300m over OM3 multi-mode fiber (MMF) or 400m over OM4 MMF via a Duplex LC connector. With high-density networking and low power consumption, this Cisco SFP-10G-SR-S provides highly stable Internet Service Provider (ISP) 10 Gigabit Ethernet communication links, Enterprise LAN & SAN Networks and other high-speed optical links. Compliant with both the SFP+ Multi-Source Agreement (MSA) and IEEE 802.3ae. DOM (Digital Optical Monitoring) supported.

FAQ for Cisco SFP-10G-SR-S

• Q1: What is the maximum distance supported by the Cisco SFP-10G-SR-S compatible transceiver? A1: It reaches up to 26m on legacy OM1 fiber, 82m on OM2, up to 300m on standard OM3 multi-mode fiber, and up to 400m over optimized OM4 multi-mode fiber.

• Q2: What does the "-S" suffix mean in Cisco SFP-10G-SR-S?
  A2: The "-S" stands for "S-Class." Cisco introduced S-Class optics for mainstream commercial/enterprise applications. It omits features not typically used in standard enterprise setups, such as OTN (Optical Transport Network) protocol support.

• Q3: What is the primary difference between SFP-10G-SR and SFP-10G-SR-S?
  A3: Performance-wise on Ethernet networks, they are identical (10G, 850nm, 300m MMF). However, the non-S module supports alternate transport features like WAN Phy and FCoE/OTN, whereas the S-Class module is strictly optimized for Ethernet.

• Q4: Will this compatible module work inside a 1G SFP slot on a Cisco switch?
  A4: No. SFP+ modules require an native 10G slot and cannot downgrade to run inside a hardware slot strictly restricted to legacy 1G SFP speeds.

• Q5: Can I plug a 1G SFP transceiver into the opposite side of a link running the SFP-10G-SR-S?
  A5: No. Their data speeds mismatch.Both ends of an active optical fiber link must operate at identical transmission data speeds (10Gbps to 10Gbps).

• Q6: What wavelength does the SFP-10G-SR-S operate on?
  A6: This module transmits and receives traffic over a short-wave 850nm wavelength.
