Sumitomo Electric SCP6F86-GL-CWH SFP Transceiver

The Sumitomo Electric SCP6F86-GL-CWH is a hot-pluggable SFP (Small Form-factor Pluggable) optical transceiver module designed for multimode short-reach applications. It supports multi-rate operation including 1.25 Gbit/s (1000BASE-SX Gigabit Ethernet), 1.0625 Gbit/s (1G Fibre Channel), and up to 2.125 Gbit/s (2G Fibre Channel), providing a bidirectional optical interface in a compact MSA-compliant package.This module operates at a nominal wavelength of 850 nm using a VCSEL (Vertical Cavity Surface Emitting Laser) transmitter and a PIN photodiode receiver. It is optimized for multimode fiber (MMF, 50/125 µm OM2/OM3) with a typical transmission distance of up to 500 m on OM2 fiber and up to 300–550 m depending on fiber bandwidth and data rate. The optical link budget supports reliable performance with low bit error rates (better than 10⁻¹²) over the specified reach. Transmitter average output power and receiver sensitivity comply with 1000BASE-SX and equivalent Fibre Channel multimode specifications.
The SCP6F86-GL-CWH complies with the SFP MSA (INF-8074i), IEEE 802.3z 1000BASE-SX, and Fibre Channel standards (including 200-MS-SN-I and 200-M6-SN-I). It features digital diagnostic monitoring (DDM/DOM) with internal calibration compliant with SFF-8472, enabling real-time reporting of transmitted and received optical power, laser bias current, temperature, and supply voltage via the I²C interface for performance monitoring and fault isolation.
Optical connectivity is realized through a duplex LC connector. Key operational features include Loss of Signal (LOS) detection and assertion, automatic laser shutdown (ALS) for Class 1 eye safety compliance, and hot-swap support. The module uses the standard 20-pin SFP electrical interface with a single +3.3 V power supply and low power consumption (typically below 1 W), making it suitable for high-density port configurations in switches, routers, storage area networks, and enterprise equipment.
Environmental specifications include RoHS compliance, a commercial operating temperature range of 0°C to +70°C, high humidity tolerance, and built-in ESD protection. This SFP transceiver is primarily used for short-reach multimode links in data centers, enterprise campus networks, or Fibre Channel SAN fabrics where 850 nm multimode fiber infrastructure is deployed.
The module integrates with network management systems for remote monitoring where DDM is utilized. Installation requires standard fiber optic cleaning procedures, correct Tx/Rx fiber polarity, and adherence to minimum bend radius guidelines for duplex LC patch cords. The Sumitomo Electric SCP6F86-GL-CWH offers a reliable, cost-effective, and high-performance solution for multimode optical transport at rates from 1.0625 Gbit/s to 2.125 Gbit/s.
