10G SFP+ LR (10km) Optical Transceiver Module
Product Overview
The Apex 10G SFP+ LR module is the standard 10 Gigabit single mode interface: a 1310nm DFB transmitter and PIN receiver delivering 10GBASE-LR over one pair of single mode fiber to 10km. It is the part most 10G ports in enterprise, campus and carrier networks were designed around.
LR sits between the multimode SR grade at 300m and the longer reach ER and ZR grades. It is the default choice for building to building links, switch uplinks, metro access hand offs and data centre runs where the span is under 10km, and it interoperates with 10GBASE-LW and 10GBASE-LR ports on transport equipment.
Every module is burnt in and tested for optical power, wavelength and error rate, reports temperature, voltage and optical levels through DDM, and is coded for the host platform you name. The 10km LR grade is held in stock for same day quoting, and the multimode SR, 40km ER and 80km ZR grades are available from the same line.

Applications
Building and Campus Backbone
Connects switches and routers between buildings or floors at 10G over the single mode cable already installed in the risers and ducts.
Switch and Router Uplinks
Provides the standard 10G uplink between access, aggregation and core switches where the run sits inside the 10km reach.
Metro Access Hand Off
Delivers a 10G service to a customer or an aggregation point at 10km, using the LR grade that most carrier and enterprise ports expect.
Compatibility
10G SFP+ LR modules are coded to the host platform you specify, including switches, routers, OLT equipment and media converters, and are tested on live ports before shipment. Where the span is shorter than 300m and the cable is multimode we quote the SR grade instead, and for 40km or 80km spans the ER and ZR grades are the correct parts.

Frequently Asked Questions
What is the difference between SR, LR and ER on 10G SFP+?
SR is 850nm over multimode fiber to 300m, LR is 1310nm over single mode fiber to 10km and ER is 1310nm over single mode fiber to 40km. The fiber type in the duct decides which one fits.
Can a 10G LR module run on multimode fiber?
No. LR is designed for single mode fiber and needs the matching fiber type at both ends. For multimode runs under 300m use the SR grade, and for older multimode plant the LRM grade.
Is the 10G LR grade in stock?
Yes. The standard 10km LR module is held in stock and quoted the same day, with SR, ER, ZR and WDM grades available from the same line.
Do you code these modules for a specific switch?
Yes. Send the host model and we code the module for that platform, with a test report kept against the module serial number.
